RabbitCore RCM3365/RCM3375

1. INTRODUCTION

The RCM3365 and RCM3375 RabbitCore modules feature a compact module that incorporates the latest revision of the power-

ful Rabbit® 3000 microprocessor, flash memory, mass storage (NAND flash), static RAM, and digital I/O ports. The RCM3365 and RCM3375 present a new form of embedded flexibility with removable (“hot-swappable”) memory cards. The RCM3365 and RCM3375 both have an integrated 10/100Base-T Ethernet port, and provide for LAN and Internet-enabled systems to be built as easily as serial-communication systems.

In addition to the features already mentioned above, the RCM3365 and RCM3375 have two clocks (main oscillator and real-time clock), reset circuitry , and the circuitry necessary for management of battery backup of the Rabbit 3000’s internal real-time clock and the static RAM. Two 34-pin headers bring out the Rabbit 3000 I/O bus lines, parallel ports, and serial ports.

The RCM3365/RCM3375’s mass-storage capabilities make them suited to running the optional Dynamic C FAT file system module where data are stored and handled using the same directory file structure commonly used on PCs. A removable xD-Picture Card can be hot-swapped to transfer data quickly and easily using a standardized file system that can be read away from the RCM3365/RCM3375 installation.

The RCM3365 or RCM3375 receives +3.3 V power from the customer-supplied motherboard on which it is mounted. The RCM3365 and RCM3375 can interface with all kinds of CMOS-compatible digital devices through the motherboard.

The Development Kit has what you need to design your own microprocessor-based system: a complete Dynamic C software development system including the Dynamic C FAT File System module, and a Prototyping Board that allows you to evaluate the RCM3365 or RCM3375, and to prototype circuits that interface to the RCM3365 or RCM3375 module.

User’s Manual 1

The RCM3365 and RCM3375 are programmed over a standard PC serial port through a serial programming cable supplied with the Development Kit, and can also be programed through a USB port with an RS-232/USB converter, or directly over an Ethernet link using the Dynamic C download manager with or without a RabbitLink; Dynamic C RabbitSys may also be used with a RabbitSys-enabled RCM3365 over an Ethernet link.

Appendix A provides detailed specifications for the RCM3365 and the RCM3375.

User’s Manual 3

1.2 Comparing the RCM3900/RCM3910 and RCM3365/RCM3375

We can no longer obtain certain components for the RCM3365/RCM3375 RabbitCore modules that support the originally specified -40°C to +70°C temperature range. Instead of changing the design of the RCM3365/RCM3375 RabbitCore modules to handle available components specified for the original temperature range, we decided to develop a new product line — the RCM3 900 s e ries.

The RCM3900 series of RabbitCore modules is similar in form, dimensions, and function to the RCM3365/RCM3375 modules. We strongly recommend that existing RCM3365/ 3375 customers and designers of new systems consider using the new RCM3900 series RabbitCore modules.

This section compares the two lines of RabbitCore modules.

• Temperature Specifications — RCM3365/RCM3375 RabbitCore modules manufac-

tured after May, 2008, are specified to operate at 0°C to +70°C. The RCM3900/ RCM3910, rated for -20°C to +85°C, are offered to customers requiring a larger temperature range after May, 2008.

• Removable Mass Storage — The hot-swappable xD-Picture Card™ mass storage device with up to 128MB of memory has been replaced with the miniSD Card with up to 1GB of memory. The miniSD Card is more readily available today, and is expected to remain readily available for a long time. In addition, miniSD Cards provide a significantly larger memory capacity, which has been requested by customers. The trade-off for the larger memory capacity is that the data transfer rate to/from the miniSD Card is about an order of magnitude slower than to/from the xD-Picture Card.

NOTE: RCM3365/RCM3375 RabbitCore modules may eventually be discontinued

because of changes to the xD-Picture Card™.

• Serial Ports — Serial Port B, available as either a clocked serial port or an asynchro-

nous serial port on the RCM3365/RCM3375, is used by the RCM3900/RCM3910 as a clocked serial peripheral interface (SPI) for the miniSD™ Card, and is not brought out for customer use.

• General-Purpose I/O — PD2, a configurable I/O pin on the RCM3365/RCM3375, is used to enable/disable the RabbitNet SPI interface when the RCM3365/RCM3375 is installed on the Prototyping Board. The RCM3900/RCM3900 use PD2 to detect whether the miniSD™ Card is installed, and so PD2 is not brought out for customer use on the RCM3900/RCM3910.

• Maximum Current — The RCM3365/RCM3375 draws 250 mA vs. the 325 mA required by the RCM3900/RCM3910.

• LEDs — The SPEED and user (USR/BSY)LED locations have been swapped between the RCM3365/RCM3375 and the RCM3900/RCM3910, the LNK/ACT LEDs have been combined to one LED on the RCM3900/RCM3910, and the RCM3900/RCM3910 has an FDX/COL LED instead of the FM LED on the RCM3365/RCM3375. The LED placements on the boards remain unchanged.

4 RabbitCore RCM3365/RCM3375

• Ethernet chip — A different Ethernet controller chip is used on the RCM3900/ RCM3910. The Ethernet chip is able to detect automatically whether a crossover cab le or a straight-through cable is being used in a particular setup, and will configure the signals on the Ethernet jack inte rf ace.

• Dynamic C — As long as no low-level FA T file system calls or direct xD-Picture Card access calls to the

NFLASH.LIB library were used in your application develo ped f or t he

RCM3365/RCM3375, you may run that application on the RCM3900/RCM3910 after you recompile it using Dynamic C v. 9.60.

NOTE: The Dynamic C RabbitSys option for programming an RCM3365 over an

Ethernet link is not supported for the RCM3900.

1.3 Advantages of the RCM3365 and RCM3375

• Fast time to market using a fully engineered, “ready-to-run/ready-to-program” microprocessor core.

• Competitive pricing when c ompar ed with the alternative of purchasing and assembling individual components.

• Easy C-language program development and debugging

• Program download utility (Rabbit Field Utility) and cloning board options for rapid

production loading of programs.

• Generous memory size allows large programs with tens of thousands of lines of code, and substantial data storage.

• Integrated Ethernet port for network connectivity, with royalty-free TCP/IP software.

• Ideal for network-enabling security and access systems, home automation, HVAC

systems, and industrial controls

6 RabbitCore RCM3365/RCM3375

1.4.2 Software

The RCM3365 an d the RCM 3375 are programm ed using v ersion 9.24 or later o f Dynamic C. A compatible version is included on the Development Kit CD-ROM.

Rabbit is also offering RCM3365 RabbitCore modules preloaded with Dynamic C RabbitSys firmware to allow these modules to run Dynamic C RabbitSys. Dynamic C RabbitSys requires Dynamic C version 9.30 or later, and allows the RCM3365 to be accessed via an Ethernet connection for remote application updates, and for remote monitoring and control. A RabbitSys Development Kit is available with all the hardware and software tools that are needed to develop a RabbitSys application.

Dynamic C v. 9.60 includes the popular µC/OS-II real-time operating system, point-topoint protocol (PPP), FAT file system, RabbitWeb, and other select libraries that were previously sold as individual Dynamic C modules.

Rabbit also offers for purchase the Rabbit Embedded Security Pack featuring the Secure Sockets Layer (SSL) and a specific Advanced Encryption Standard (AES) library. In addition to the Web-based technical support included at no extra charge, a one-year telephonebased technical support subscription is also available for purchase.

NOTE: Version 2.10 or later of the Dynamic C FAT file system module is required to use

the FAT file system with the RCM3365 and RCM3375 models.

1.4.3 Accessories

Rabbit has available a USB Removable Memory Card Reader and a Connector Adapter Board.

• USB Removable Memory Card Reader (Part No. 20-101-1104)—allows you to read data from the xD-Picture Card via your PC.

• Connector Adapter Board (Part No. 151-0114)—allows you to plug the RCM3365/ RCM3375 whose headers have a 2 mm pitch into header sockets with a 0.1" pitch.

1.4.4 Onlin e Documentation

The online documentation is installed along with Dynamic C, and an icon for the documentation menu is placed on the workstation’s desktop. Double-click this icon to reach the menu. If the icon is missing, use your browser to find and load default.htm in the docs folder, found in the Dynamic C installation folder.

The latest versions of all documents are always available for free, unregistered download from our Web sites as well.

2. GETTING S TARTED

This chapter explains how to set up and use the RCM3365/ RCM3375 modules with the accompanying Prototyping Board.

NOTE: It is assumed that you have a Development Kit. If you purc hased an RCM3365 or

RCM3375 module by itself, you will have to adapt the information in this chapter and elsewhere to your test and development setup.

2.1 Install Dynamic C

To develop and debug programs for the RCM3365/RCM3375 (and for all other Rabbit hardware), you must install and use Dynamic C.

If you have not yet installed Dynamic C version 9.24 (or a later version), do so now by inserting the Dynamic C CD from the Development Kit in your PC’s CD-ROM drive. If autorun is enabled, the CD installation will begin automatically.

If autorun is disabled or the installation otherwise does not start, use the Windows

Start | Run menu or Windows Disk Explorer to launch setup.exe from the root folder

of the CD-ROM. The installation program will guide you through the installation process. Most steps of the

process are self-explanatory. Dynamic C uses a COM (serial ) port to communica te with the tar get deve lopment sy stem.

The installation allows you to choose the COM port that will be used. The default selection is COM1. You may select any available port for Dynamic C’s use. If you are not certain which port is available, select COM1. This selection can be changed later within Dynamic C.

NOTE: The installation utility does not check the selected COM port in any way. Speci-

fying a port in u se by a not her device (mouse, modem, etc.) may l ea d to a message such as

"could not open serial port" when Dynamic C is started.

Once your installation is complete, you will have up to three icons on your PC desktop. One icon is for Dynamic C, one opens the documentation menu, and the third is for the Rabbit Field Utility, a tool used to download precompiled software to a target system.

If you have purchased the optional Dynamic C Rabbit Embedded Security Pack, install it after installing Dynamic C. You must install the Rabbit Embedded Security Pack in the same directory where Dynamic C was installed.

User’s Manual 9

2.2 Hardware Connections

There are three steps to connecting the Prototyping Board for use with Dynamic C and the sample programs:

1. Attach the RCM3365/RCM3375 module to the Prototyping Board.

2. Connect the serial programming cable between the RCM3365/RCM3375 and the workstation PC or if you have an RCM3365 with RabbitSys firmware you may connect the RCM3365 and the PC using Ethernet cables.

3. Connect the power supply to the Prototyping Board.

2.2.1 Step 1 — Attach Module to Prototyping Board

Turn the RCM3365/RCM3375 module so that the Ethernet jack is facing the direction shown in Figure 2 below. Align the pins from headers J3 and J4 on the bottom side of the modul e into header sockets JA and JB on the Prototyping Board. The picture card (NAND flash) does not have to be inserted into connector J6 on the RCM3365/RCM3375 at this time.

Figure 2. Install the RCM3365/RCM3375 Module on the Prototyping Board

NOTE: It is important that you line up the pins on headers J3 and J4 of the RCM3365/

RCM3375 module exactly with th e cor re spon din g pins of header sockets JA and JB on the Prototyping Board. The header pins may become bent or damaged if the pin alignment is offset, and the module will not work. Permanent electrical damage to the module may also result if a misaligned module is powered up.

Press the module’s pins firmly into the Prototyping Board header sockets—press down in the area above the header pins using your thumbs or fingers over the header pins as shown in Figure 2. Do not press down on the picture card connector (J6) unless the picture card is installed, but rather press down on the circuit board along the edge by the connector. Also, do not press down on the middle of the module t o avoid fl exing the module, which could damag e the module or components on the module.

Should you need to remove the module, grasp it with your fingers along the sides by the connectors and gently work the module up to pull the pins away from the sockets where they are installed. Do not remove the module by grasping it at the top and bottom.

10 RabbitCore RCM3365/RCM3375

2.2.2 Step 2 — Connect Serial Programming Cable

The serial programming cable connects the RCM3365/RCM3375 to the PC running Dynamic C to download programs and to monitor the module during debugging.

Connect the 10-pin connector of the serial programming cable labeled

PROG to header J1

on the RCM3365/RCM3375 module as shown in Figure 3. There is a small dot on the circuit board next to pin 1 of header J1. Be sure to orient the marked (usually red) edge of the cable towards pin 1 of the connector. (Do not use the DIAG connector , which is used for a nonprogramming serial connection.)

Figure 3. Connect Serial Programming Cable and Power Supply

NOTE: Be sure to use the serial programming cable (part number 101-0542) supplied

with this Development Kit—the serial programming cable has blue shrink wrap around the RS-232 converter section located in the middle of the cable. Pr ogramming cables with clear o r r ed s hr i nk w ra p f ro m o th er Rabbit kits are not desig ned to work wit h RCM3365 / RCM3375 modules.

Connect the other end of the serial programming cable to a COM port on your PC.

NOTE: Some PCs now come equipped only with a USB port . It may be possible to use

an RS-232/USB converter (Part No. 20-151--0178) with the serial programming cable supplied with the RCM3365/RCM3375 Development Kit. Note that not all RS-232/ USB converters work with Dynamic C.

User’s Manual 11

2.2.2.1 Programming via Ethernet Option

An Ethernet cable connects a RabbitSys-enabled RCM3365 to the PC running Dynamic C with Dynamic C RabbitSys via a DHCP network to download programs and to monitor the RCM3365 module during debugging.

Use a straight-through CAT 5/6 Ethernet cable to connect the Ethernet jack on the RCM3365 to a DHCP-enabled network. Y our PC should also be connected to this network—you will need a second straight-through CAT 5/6 Ethernet cable to connect the PC to the net work since only one straight-through Ethernet cable is supplied with the Development Kit.

Figure 4. Connect Ethernet Cable for Ethernet Programming Option

You may also use a crossover CAT 5/6 Ethernet cable to connect the Ethernet jack on the RCM3365 directly to your PC, but there will be additional steps required to configure the TCP/IP parameters on the RCM3365 and on your PC if your PC does not have a DHCP server. These steps are described in Appendix E.

12 RabbitCore RCM3365/RCM3375

2.2.3 Step 3 — Connect Power

When all other connections have been made, you can connect power to the Prototyping Board. Connect the wall transformer to jack J1 on the Prototyping Board as shown in Figure 3.

Plug in the wall transformer.

The core LED on the Prototyping Board should light up. The

RCM3365/RCM3375 and the Prototyping Board are now ready to be used.

NOTE: A RESET button is provided on the Prototypi ng Board to a llow a har dware reset

without disconnecting power. The RCM3365/RCM3375 can also be reset from Dynamic C by pressing <Ctrl-Y> if your PC is connected to the RCM3365/RCM3375 via the serial programming cable.

2.2.3.1 Alternate Power-Supply Connections

All Development Kits include a header connector that may be used to connect your power supply to 3-pin header J2 on the Prototyping Board. The connector may be attached either way as long as it is not offset to one side—the center pin of J2 is always connected to the positive terminal, and either edge pin is negative. The power supply should deliver 8 V to 30 V DC at 8 W.

2.3.1 Running Dynamic C via Serial Programming Cable

Dynamic C uses the serial port on your PC that you specified during installation. If you are using a USB port to connect you r computer to the RCM3365 /RCM3375 module,

choose

Communications tab.

2.3.1.1 Run a Sample Program

Options > Project Options and select “Use USB to Serial Converter” on the

Use the File menu to open the sample program PONG.C, which is in the Dynamic C

SAMPLES folder. Press function key F9 to compile and run the program. The STDIO

window will open on your PC and will display a small square bouncing around in a box. This program shows that the CPU is working. The sample program described in

Section 6.5, “Run the PINGME.C Sample Program,” tests the TCP/IP portion of the board.

2.3.1.2 Troubleshooting

If Dynamic C cannot find the target system (error message "No Rabbit Processor Detected."):

• Check that the RCM3365/RCM3375 is powered correctly — the red CORE LED on the

Prototyping Board should be lit when the RCM3365/RCM3375 is mounted on the Prototyping Board and the AC adapter is plugged in

• Check both ends of the programming cable to ensure that they are firmly plugged into the PC and the PROG connector, not the DIAG connector , is plugged in to the programming port on the RCM3365/RCM3375 with the marked (colored) edge of the programming cable towards pin 1 of the programming header.

• Ensure that the RCM3365/RCM3375 module is firmly and correctly installed in its connectors on the Prototyping Board.

• Dynamic C uses the COM port specified during installation. Select a different COM port within Dynamic C. From the Options menu, select Project Options, then select

Communications. Select another COM port from the lis t, the n cl ick OK. Press <Ctrl-Y> t o f o rce Dynamic C to r ecompil e the BI OS . I f Dynamic C still reports it is

unable to locate the target system, repeat the above steps until you locate the COM port used by the programming cable.

If Dynamic C appears to compile the BIOS successfully, but you then receive a communication error message when you compile and load the sample program, it is possible that your PC cannot handle the higher program-loading baud rate. Try changing the maximum download rate to a slower baud rate as follows.

• Locate the Serial Options dialog in the Dynamic C O ptions > Project Options > Communications menu. Select a slower Max download baud rate.

If a program compiles and loads, but then loses target communication before you can begin debugging, it is possible that your PC cannot handle the default debugging baud rate. Try lowering the debugging baud rate as follows.

• Locate the Serial Options dialog in the Dynamic C O ptions > Project Options > Communications menu. Choose a lower debug baud rate.

User’s Manual 15

2.3.2 Running Dynamic C via Ethernet Cables

The firmware needed to run RabbitSys has been preloaded on RCM3365 RabbitCore modules sold for use with Dynamic C RabbitSys. The software from the Dynamic C and the Dynamic C RabbitSys CDs must be installed on your PC. A system running RabbitSys can be connected to a DHCP network using straight-through Ethernet cables, or it can be connected directly to the PC via an Ethernet crossover cable.

• If you are connecting to a network with a DHCP server, use a CAT 5/6 straight-through Ethernet cable to connect the PC or workstation to the network, and connect the Ethernet jack on the RCM3365 to the network using a second CAT 5/6 straight-through Ethernet cable.

• If your PC or workstation is running a DHCP server, connect the CAT 5/6 Ethernet crossover cable from the PC or workstation directly to the Ethernet jack on the RCM3365. Follow the instructions below for a straight-through Ethernet cable.

TIP: It is recommended that you use one of the above options for a PC/workstation or

network with a DHCP server or the serial cable programming option when you are using the RCM3365 for the first time since these options are easier to set up and run.

• If your PC/workstation does not have a DHCP server , you will have to enter the TCP/IP parameters into the RCM3365 module and on to the PC, notebook, or workstation. See Appendix E for more information on this option.

Using DHCP Network with Straight-Through Ethernet Cables

Enable separate instruction and data spaces and select “Compile program in RabbitSys user mode” from the Dynamic C Options > Project Options > Compiler menu.

Before you compile and run a program via the Ethernet for the first time via a DHCP network, you must run the rdiscover utility by double-clicking it on your PC desktop. Your PC must be connected to the same DHCP network as the RCM3365. The utility will open a window and list the MAC addresses for any RabbitSys boards connected to the network.

Select a board from the list to display additional information such as the board’s Internet address. This is the IP address to enter when you access the Dynamic C Options > Project

Options > Communications

menu to select “Use TCP/IP Connection.” You must also enter “32023” for the Control Port and the default login values of “admin” and “password.”

2.3.2.1 Run a Sample Program

Use the File menu to open the sample program PONG.C, which is in the Dynamic C

SAMPLES folder. Press function key F9 to compile and run the program. The STDIO

window will open on your PC and will display a small square bouncing around in a box. This program shows that the CPU is working. The sample program described in

Section 6.5, “Run the PINGME.C Sample Program,” tests the TCP/IP portion of the board.

16 RabbitCore RCM3365/RCM3375

2.3.2.2 Troubleshooting

If the rdiscover utility could not find your RCM3365:

• Check that your network has a DHCP server, and that the RCM3365 and your PC are connected to the same network.

• If you compiled and ran a sample program with the RabbitSys project option disabled, you may have overwritten the RabbitSys binary file. Use the serial programming cable to connect programming header J1 on the RCM3365 to your PC COM port to reload the RabbitSys binary file via the Dynamic C Compile > Reload RabbitSys binary menu.

If the rdiscover utility could not find your RCM3365, and you were unable to reload the RabbitSys binary file, your RCM3365 does not have the firmware to support Dynamic C RabbitSys and cannot be used with Dynamic C RabbitSys.

If Dynamic C returns an error message, check that the RCM3365 is powered correctly. The red CORE LED on the Pr ototypi ng B oard s hould be lit when the RCM3365 is mounted on the Prototyping Board and the AC adapter is plugged in. Ensure that the RCM3365 module is firmly and correctly installed in its connectors on the Prototyping Board.

2.4 Where Do I Go From Here?

If the sample program ran fine, you are now ready to go on to other sample programs and to develop your own applications. The source code for the sample programs is provided to allow you to modify them for your own use. The RCM3365/RCM3375 User’s Manual also provides complete hardware reference information and describes the software function calls for the RCM3365 and the RCM3375, the Prototyping Board, and the optional LCD/keypad module.

For advanced development topics, refer to the Dynami c C User’ s Ma nual, the Dynamic C RabbitSys User’s Manual, and the Dynamic C TCP/IP User’ s Manual, also in the online documentation set.

3. RUNNING SAMPLE PROGRAMS

To develop and debug programs for the RCM3365/RCM3375 (and for all other Rabbit hardware), you must install and use Dynamic C.

3.1 Introduction

To help familiarize you with the RCM3365 and RCM3375 modules, Dynamic C includes several sample programs. Loading, executing and studying these programs will give you a solid hands-on overview of the RCM3365/RCM3375’s capabilities, as well as a quick start using Dynamic C as an application development tool.

NOTE: The sample programs assume that you have at least an elementary g ras p of the C

programming language. If you do not, see the introductory pages of the Dynamic C User’s Manual for a suggested reading list.

More complete information on Dynamic C is provided in the Dynamic C User’s Manual. In order to run the sample programs discussed in this chapter and elsewhere in this manual,

1. Your RCM3365/RCM3375 module must be plugged in to the Prototyping Board as described in Chapter 2, “Getting Started.”

2. Dynamic C must be installed and running on your PC.

3. The RCM3365/RCM3375 module must be connected to your PC either through the serial programming cable or through an Ethernet cable/network if you have a RabbitSys-enabled RCM3365.

4. Power must be applied to the RCM3365/RCM3375 through the Prototyping Board.

Refer to Chapter 2, “Getting Started,” if you need further information on these steps. Since the RCM3365 and the RCM3375 run at 44.2 MHz and are equipped with a fast pro-

gram execution SRAM, remember to allow the compiler to run the application in the fast program execution SRAM by selecting Code and BIOS in Flash, Run in RAM from the Dynamic C Options > Project Options > Compiler menu.

To run a sample program, open it with the File menu, then press function key F9 to compile and run the program.

User’s Manual 19

3.2 Sample Programs

Of the many sample programs included with Dynamic C, several are specific to the RCM3365 and the RCM3375. Sample programs illustrating the general operation of the RCM3365/RCM3375, serial communication, and the NAND flash are provided in the

SAMPLES\RCM3360 folder. Each sample program has comments that describe the purpose

and function of the program. Follow the instructions at the beginning of the sample program. Note that the RCM3365/RCM3375 must be installed on the Prototyping Board when using the sample programs described in this chapter.

• CONTROLLED.c—Demonstrates use of the digital inputs by having you turn the LEDs on the Prototyping Board on or off from the STDIO window on your PC.

Once you compile and run CONTROLLED.C, the following display will appear in the Dynamic C STDIO window.

Press “2” or “3” or “4”or “5”on your keyboard to select LED DS3 or DS4 or DS5 or DS6 on the Prototyping Board. Then follow the prompt in the Dynamic C STDIO window to turn the LED on or off.

• FLASHLED.c—Demonstrates assembly-language program by flashing the USR LED on the RCM3365/RCM3375 and LEDs DS3, DS4, DS5, and DS6 on the Prototyping Board.

• SWRELAY.c—Demonstrates the relay-switching function call using the relay installed on the Prototyping Board through screw-terminal header J17.

• TOGGLESWITCH.c—Uses costatements to detect switches S2 and S3 using debouncing. The corresponding LEDs (DS3 and DS4) will turn on or off.

Once you have loaded and executed these four programs and have an understanding of how Dynamic C and the RCM3365/RCM3375 modules interact, you can move on and try the other sample programs, or begin building your own.

20 RabbitCore RCM3365/RCM3375

3.2.1 Use of NAND Flash

The following sample programs can be found in the SAMPLES\RCM3360\NANDFlash folder. As you run most of these sample programs, you will be prompted in the Dynamic C dow to select either the

soldered-in NAND flash (RCM3365 model only) or the socketed

STDIO win-

xD-Picture Card (0 = soldered, 1 = socketed).

• NFLASH_DUMP.c—This program is a utility for dumping the nonerased contents of a NAND flash chip to the Dynamic C STDIO window, and the contents may be redirected to a serial port.

When the sample program starts running, it attempts to communicate with the userselected NAND flash chip. If this communication is successful and the main page size is acceptable, the nonerased page contents (non 0xFF) from the NAND flash page are dumped to the Dynamic C STDIO win.for inspection.

Note that an error message might appear when the first 32 pages (0x20 pages) are “dumped.” You may ignore the error message.

• NFLASH_INSPECT.c—This program is a utility for inspecting the contents of a NAND flash chip. When the sample program starts running, it attempts to communicate with the NAND flash chip selected by the user. Once a NAND flash chip is found, the user can execute various commands to print out the contents of a specified page, clear (set to zer o) all the bytes in a specified pa ge, erase (s et to FF), or wri te to specifie d pages.

CAUTION: When you run this sample program, enabling the #define NFLASH_

CANERASEBADBLOCKS macro makes it possible to write t o bad bloc ks. The first two

blocks on the xD-Picture Card are mark ed bad to prot ec t the configuration data needed to use the card in a digital camera or a PC. You will only be able to use the xD-Picture Card in Rabbit-based systems if either of the first two blocks is written to.

• NFLASH_LOG.c—This program runs a simple Web server and stores a log of hits in the NAND flash. As long as the xD-Picture Card is plugged in to its connector J6, this sample program will log hits to the xD-Picture Card. Remove the xD-Picture Card if you wish to log hits on the soldered-in NAND flash (RCM3365 model only).

This log can be viewed and cleared from a browser by connecting the RJ-45 jack on the RCM3365 to your PC as described in Section 6.1. The sidebar on the next page explains how to set up your PC or notebook to view this log.

User’s Manual 21

Follow these instructions to set up your PC or notebook. Check with your administrator if you are unable to change the settings as described here since you may need administrator privileges. The instructions are specifically for Windows 2000, but the interface is similar for other versions of Windows.

TIP: If you are using a PC that is already on a network, you will disconnect the PC

from that network to run these sample programs. Write down the existing settings before changing them to facilitate restoring them when you are finished with the sample programs and reconnect your PC to the network.

1. Go to the control panel (Start > Settings > Control Panel), and then double-click the Network icon.

2. Select the network interface card used for the Ethernet interface you intend to use (e.g., TCP/IP Xircom Credit Card Network Adapter) and click on the “Properties” button. Depending on which version of Windows your PC is running, you may have to select the “Local Area Connection” first, and then click on the “Propertie s” button to bring up the Ethernet interface dialog. Then “Configure” your interface card for a “10Base-T Half-Duplex” or an “Auto-Negotiation” connection on the “Advanced” tab.

NOTE: Your network interface card will likely have a different name.

3. Now select the IP Address tab, and check Specify an IP Address, or select TCP/IP and click on “Properties” to assign an IP address to your computer (this will disable “obtain an IP address automatically”):

IP Address : 10.10.6.101 Netmask : 255.255.255.0 Default gateway : 10.10.6.1

4. Click <OK> or <Close> to exit the various dialog boxes.

As long as you have not modified the TCPCONFIG 1 macro in the sample program, enter the following server address in your Web browser to bring up the Web page served by the sample program.

http://10.10.6.100

Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library. This sample program does not exhibit ideal behavior in its method of writing to the

NAND flash. However, the inefficiency attributable to the small amount of data written in each append operation is offset somewhat by the expected relative infrequency of these writes, and by the sample program's method of “walking” through the flash blocks when appending data as well as when a log is cleared.

• NFLASH_ERASE.c—This program is a utility to erase all the good blocks on a NAND flash chip. When the program starts running, it attempts to establish communication with the NAND flash chip selected by the user. If the communication is successful, the progress in erasing the blocks is displayed in the Dynamic C STDIO window as the blocks are erased.

22 RabbitCore RCM3365/RCM3375

3.2.2 Hot-Swapping xD-Picture Card

The sample programs in this section require that you have installed the Dynamic C FAT File System module, which is included with the RCM3365/RCM3375 Development Kit.

NOTE: Versions of the Dynamic C FAT File System prior to 2.10 did not use unique

volume labels, so hot-swapping two xD-Picture Card that were both formatted with older versions of the FAT File System may cause cache recovery errors

The following sample program can be found in the SAMPLES\RCM3360\NANDFlash folder. Since Rabbit-based systems do not implement the xD-Picture Car d™ specification for data storage, hot-swap only xD-Picture Cards that you plan to have formatted for use in Rabbit-based systems.

• FAT_HOT_SWAP_3365_75.c—This program demonstrates how to hot-swap the xD- Picture Card on the RCM3365/RCM3375. Once you have compiled the sample

program and it is running, press switch SW3 on the Prototyping Board or press any keyboard key on your PC to signal your intent to do a hot-swap. Remove the xD- Picture Card and insert a new xD-Picture Card (or replace the original one) when prompted to do so in the Dynamic C STDIO window or when the green LED (DS4) on the Prototyping Board lights up. Do not remove the xD-Picture Card until you are prompted or signaled by the LED!

The the xD-Picture Card can only be hot-swapped when the xD-Picture Card is “unmounted.” This sample program “unmounts” the xD-Picture Card when it detects a keyboard hit or SW3 press. Then it waits for a new xD-Picture Card to be inserted.

The following sample program can be found in the SAMPLES\FileSystem\ folder.

• FAT_HOT_SWAP.c—This program demonstrates how to hot-swap the xD-Picture Card on boards that support the xD-Picture Card and have their data bus buffered.

Once you have compiled the sample program and it is running, press any keyboard key on your PC to signal your intent to do a hot-swap. Remove the xD-Picture Card and insert a new xD-Picture Card (or replace the original one) when prompted to do so in the Dynamic C STDIO window. Do not remove the xD-Picture Card until you are prompted!

The xD-Picture Card can only be hot-swapped when the xD-Picture Card is “unmounted.” This sample program “unmounts” the xD-Picture Card when it detects a keyboard press. Then it waits for a new xD-Picture Card to be inserted.

3.2.3 Serial Co mmunication

The following sample programs can be found in the SAMPLES\RCM3360\SERIAL folder.

FLOWCONTROL.C—This program demonstrates hardware flow control by configuring

•

Serial Port F for CTS /RTS with serial data coming from TxE (Ser ial P ort E) a t 115,200 bps. One character at a time is received and is displayed in the

STDIO window.

To set up the Prototyping Board, you will need to tie TxE and RxE together on the RS-232 header at J14, and you will also tie TxF and RxF together as shown in the diagram.

J14

TxE RxE GND TxF RxF 485+ GND 485

A repeating triangular pattern should print out in the

STDIO window . The program periodically switches R TS (TxF) flow control on or off to

demonstrate the effect of hardware flow control.

• PARITY.C—This program demonstrates the use of parity modes by repeatedly sending byte values 0–127 from Serial Port E to Serial Port F. The program will switch between generating parity or not on Serial Port E. Serial Port F will always be checking parity, so parity errors should occur during every other sequence.

To set up the Prototyping Board, you will need to tie TxE and RxF together on the RS-232 header at J14 as shown in the diagram.

The Dynamic C STDIO window will display the error

J14

TxE RxE GND TxF RxF 485+ GND 485

sequence.

• SIMPLE3WIRE.C—This program demonstrates basic RS-232 serial communication. Lower case characters are sent by TxE, and are received by RxF. The characters are converted to upper case and are sent out by TxF , are received by RxE, and are displayed in the Dynamic C STDIO window.

To set up the Prototyping Board, you will need to tie TxE and RxF together on the RS-232 header at J14, and you will also tie RxE and TxF together as shown in the diagram.

J14

TxE RxE GND TxF RxF 485+ GND 485

• SIMPLE5WIRE.C—This program demonstrates 5-wire RS-232 serial communication by providing flow control (RTS/CTS) on Serial Port F and data flow on Serial Port E.

To set up the Prototyping Board, you will need to tie TxE and RxE together on the RS-232 header at J14, and you will also tie TxF and RxF together as shown in the diagram.

J14

TxE RxE GND TxF RxF 485+ GND 485

Once you have compiled and run this program, you can test flow control by disconnecting TxF from RxF while the program is running. Characters will no longer appear in the STDIO window, and will display again once TxF is connected back to RxF. (Do not disconnect the data path between TxE and RxE.)

24 RabbitCore RCM3365/RCM3375

• SWITCHCHAR.C—This program transmits and then receives an ASCII string on Serial Ports E and F. It also displays the serial data received from both ports in the

STDIO

window. To set up the Prototyping Board, you will need to tie

TxE and RxF together on the RS-232 header at J14, and you will also tie RxE and TxF together as shown in the diagram.

J14

TxE RxE GND TxF RxF 485+ GND 485

Once you have compiled and run this program, press and release S2 on the Prototyping Board to send a message from Serial Port E to Serial Port F; press and release S3 on the Prototyping Board to send a message from Serial Port F to Serial Port E. The data sent between the serial ports will be displayed in the

STDIO window.

Two sample programs, SIMPLE485MASTER.C and SIMPLE485SLAVE.C, are available to illustrate RS-485 master/slave communication. To run these sample programs, you will need a second Rabbit-based system with RS-485—the second system may be another RCM3365/RCM3375, or it may be any Rabbit single-board computer or RabbitCore module that supports RS-485 serial communication as long as you use the master or slave sample program associated with that board.

Before running either of these sample programs on the RCM3365/RCM3375 assembly, make sure pins 1–2 and pins 5–6 are jumpered together on header JP5 to use the RS-485 bias and termination resistors. The sample programs use Serial Port C as the RS-485 serial port, and they use PD7 to enable/disable the RS-485 transmitter.

The RS-485 connections between the slave and master devices are as follows.

• RS485+ to RS485+

• RS485– to RS485–

• GND to GND

• SIMPLE485MASTER.C—This program demonstrates a simple RS-485 transmission of lower case letters to a slave. The slave will send back converted upper case letters back to the master and display them in the STDIO window. Use SIMPLE485SLAVE.C to program the slave—reset the slave before you run SIMPLE485MASTER.C on the master.

• SIMPLE485SLAVE.C—This program demonstrates a simple RS-485 transmission of lower case letters to a master. The slave will send back converted upper case letters back to the master and display them in the STDIO window. Compile and run this program on the slave before you use SIMPLE485MASTER.C to program the master.

3.2.4 Real-Time Clock

If you plan to use the real-time clock functionality in your application, you will need to set the real-time clock. Set the real-time clock using the SETRTCKB.C sample program from the Dynamic C SAMPLES\RTCLOCK folder, using the onscreen prompts. The RTC_

TEST.C

sample program in the Dynamic C SAMPLES\RTCLOCK folder provides addi-

tional examples of how to read and set the real-time clock.

User’s Manual 25

3.2.5 RabbitNet

Sample programs are available for each RabbitNet peripheral card, and can be found in the Dynamic C

SAMPLES\RabbitNet folder. When you run any of these sample programs

in conjunction with the RCM3365/RCM3375 and the Prototyping Board, you need to add the line

#use rcm33xx.lib

at the beginning of the sample program.

TIP: You need to add #use rcm33xx.lib at the beginning of any sample program

that is not in the Dynamic C SAMPLES\RCM3360 folder.

3.2.6 Other Sample Programs

Section 6.6 describes the TCP/IP sample programs, and Appendix C.7 provides sample programs for the optional LCD/keypad module that can be installed on the Prototyping Board.

PB0, PC4, and PC5 are used for the SPI interface to the serial flash on the RCM3300 and the RCM3310, but are available on the other modules. PB0 on the RCM3365 and the RCM3375 is used to sense whether the removable xD-Picture Card card is installed. If you need PB0 for other purposes, you may remove the surface-mount resistor at R96 (Figure A-5 shows the location of R96).

Headers J3 and J4 are

standard 2 × 34 headers with a nominal 2 mm pitch. An RJ-45 Ether-

net port is also included with the RCM3365/RCM3375. Pins 29–32 on header J3 are configured using 0 Ω resistors at locations JP4, JP5, JP7, and

JP7 to be PD3, PD2, PD7, and PD6 respectively. They may also be reconfigured to carry the Ethernet signals TPO+, TPO–, TPI+, and TPI–.

Pins 33 and 34 on header J3 are wired to carry the LINK and ACT signals that illuminated the corresponding LEDs on the RCM3365/RCM3375 module. These signals may be “disconnected” by removing 0 Ω surface-mount resistors R41 and R42 (Figure A-5 shows the

Notes

1. When using pins 33–34 on header J3 to drive LEDs, these pins can handle a sinking current of up to 8 mA.

2. The VRAM voltage is temperature-dependent. If the VRAM voltage drops below about

1.2 V to 1.5 V, the contents of the battery-backed SRAM may be lost. If VRAM drops below 1.0 V, the 32 kHz oscillator could stop running. Pay careful attention to this voltage if you draw any current from this pin.

3. Do not overload the /IOWR line because the NAND flash memories have critical timing requirements. In some cases it may be necessary to buffer /IOWR on the motherboard.

32 RabbitCore RCM3365/RCM3375

4.1.1 Memory I/O Interface

The Rabbit 3000 address lines (A0–A18) and all the data lines (D0–D7) are routed internally to the onboard flash memory and SRAM chips. I/0 write (/IOWR) and I/0 read (/IORD) are available for interfacing to external devices—pay attention to the loading on these two signals if you use them since these signals are also used by the RCM3365/ RCM3375.

Parallel Port A can also be used as an external I/O data bus to isolate external I/O from the main data bus. Parallel Port B pins PB2–PB7 can also be used as an auxiliary address bus.

When using the external I/O bus for a digital output or the LCD/keypad module on the Prototyping Board, or for any other reason, you must add the following line at the beginning of your program.

#define PORTA_AUX_IO // required to enable external I/O bus

4.1.2 Other Inputs and Outputs

The status, /RESET_IN, SMODE0, and SMODE1 I/O are normally associated with the programming port. Since the status pin is not used by the sys tem once a program has been downloaded and is running, the status pin can then be used as a general-purpose CMOS output. The programming port is described in more detail in Section 4.2.3.

/RES is an output from the reset circuitry that can be used to reset external peripheral devices.

4.1.3 LEDs

The RCM3365/RCM3375 has five status LEDs located beside the RJ-45 Ethernet jack:

ACT, LINK, SPEED, FM, and USR.

The yellow ACT LED at DS1 indicates network activity. The green LINK LED at DS2 indicates that the RCM3365/RCM3375 is connected to a

working network. The green SPEED LED at DS4 is on to indicate when the RCM3365/RCM3375 is con-

nected to a 100Base-T Ethernet connection. The FM LED at DS3 blinks when data are being written to or read from the flash mass-

storage device. The red USR LED at DS3 is a user-programmable LED, which is controlled by PD0 on

the Rabbit 3000’s Parallel Port D. The sample program FLASHLED.C provided in the Dynamic C SAMPLES\RCM3360 folder shows how to set up and use this userprogrammable LED.

User’s Manual 33

4.2 Serial Communication

The RCM3365/RCM3375 does not have any serial transceivers directly on the board. However, a serial interface may be incorporated into the board the RCM3365/RCM3375 is mounted on. For example, the Prototyping Board has RS-232 and RS-485 transceiver chips.

4.2.1 Serial Ports

There are six serial ports designated as Serial Ports A, B, C, D, E, and F. All six serial ports can operate in an asynchronous mode up to the baud rate of the system clock divided by 8. An asynchronous port can handle 7 or 8 data bits. A 9th bit address scheme, where an additional bit is sent to mark the first byte of a message, is also supported.

Serial Port A is normally used as a programming port, but may be used either as an asynchronous or as a clocked serial port once the RCM3365/RCM3375 has been programmed and is operating in the Run Mode.

Serial Port B is available on the RCM3365/RCM3375, and may be used as an asynchronous port. PB0 is used to enable Dynamic C to detect whether the xD-Picture Card is installed. If the card detect is not needed by your application program, you may remove R96 (see Figure A-5) to disable the xD-Picture Card detect, and then use Serial Port B as a clocked serial port.

Serial Ports C and D can also be operated in the clocked serial mode. In this mode, a clock line synchronously clocks the data in or out. Either of the two communicating devices can supply the clock.

Serial Ports E and F can also be configured as HDLC serial ports. The IrDA protocol is also supported in SDLC format by these two ports.

4.2.2 Ethernet Port

Figure 8 shows the pinout for the RJ-45 Ethernet port (J2). Note that some Ethernet connectors are numbered in reverse to the order used here.

RJ-45 Jack

Three LEDs are placed next to the RJ-45 Ethernet jack, one to indicate an Ethernet link (LINK) one to indicate Ethernet activity (ACT), and one to indicate the 10 /100Base-T s peed.

The RJ-45 connector is shielded to minimize EMI effects to/from the Ethernet signals.

34 RabbitCore RCM3365/RCM3375

4.2.3 Serial Programming Port

The RCM3365/RCM3375 is programmed either through the serial programming port, which is accessed using header J1 or through the Ethernet jack. The RabbitLink may be used to provide a serial connection via the RabbitLink’s Ethernet jack. The programming port uses the Rabbit 3000’s Serial Port A for communication; Serial Port A is not used when programming is done over an Ethernet connection on a board running Dynamic C RabbitSys. Dynamic C uses the programming port to download and debug programs.

The programming port is also used for the following operations.

• Cold-boot the Rabbit 3000 on the RCM3365/RCM3375 after a reset.

• Remotely download and debug a program over an Ethernet connection using the

RabbitLink EG2110.

• Fast copy designated portions of flash memory from one Rabbit-based board (the master) to another (the slave) using the Rabbit Cloning Board.

In addition to Serial Port A, the Rabbit 3000 startup-mode (SMODE0, SMODE1), status, and reset pins are available on the programming port.

The two startup mode pins determine what happens after a reset—the Rabbit 3000 is either cold-booted or the program begins executing at address 0x0000.

The status pin is used by Dynamic C to determine whether a Rabbit microprocessor is present. The status output has three different programmable functions:

1. It can be driven low on the first op code fetch cycle.

2. It can be driven low during an interrupt acknowledge cycle.

3. It can also serve as a general-purpose CMOS output.

The /RESET_IN pin is an external input that is used to reset the Rabbit 3000 and the RCM3365/RCM3375 onboard peripheral circuits. The serial programming port can be used to force a hard reset on the RCM3365/RCM3375 by asserting the /RESET_IN signal. No equivalent functionality exists for programming over an Ethernet connection on a board running Dynamic C RabbitSys.

Alternate Uses of the Serial Programming Port

All three clocked Serial Port A signals are available as

• a synchronous serial port

• an asynchronous serial port, with the clock line usable as a general CMOS I/O pin

The programming port may also be used as a serial port once the application is running. The SMODE pins may then be used as inputs and the status pin may be used as an output.

Refer to the Rabbit 3000 Microprocessor User’s Manual for more information.

User’s Manual 35

4.3 Serial Programming Cable

The programming cable is used to connect the serial programming port of the RCM3365/ RCM3375 to a PC serial COM port. The programming cable converts the RS-232 voltage levels used by the PC serial port to the CMOS voltage levels used by the Rabbit 3000.

When the

PROG connector on the programming cable is connected to the RCM3365/

RCM3375 serial programming port at header J1, programs can be downloaded and debugged over the serial interface.

The DIAG connector o f t h e p r o g r amming cabl e m a y b e u s ed on header J 1 o f th e RC M3365/ RCM3375 with the RCM3365/RCM3375 operating in the Run Mode. This allows the programming port to be used as a regular serial port.

4.3.1 Changing Between Program Mode and Run Mode

The RCM3365/RCM3375 is automatically in Program Mode when the PROG connector on the programming cable is attached, and is automatically in Run Mode when no programming cable is attached. When the Rabbit 3000 is reset, the operating mode is determined by the state of the SMODE pins. When the programming cable’s PROG connector is attached, the SMODE pins are pulled high, placing the Rabbit 3000 in the Program Mode. When the programming cable’s PROG connector is not attached, the SMODE pins are pulled low, causing the Rabbit 3000 to operate in the Run Mode.

gramming port.

4.3.2 Standalone Operation of the RCM3365/RCM3375

The RCM3365/RCM3375 must be programmed via the Prototyping Board or via a similar arrangement on a customer-supplied board. Once the RCM3365/RCM3375 has been programmed successfully, remove the serial programming cable from the programming connector and reset the RCM3365/RCM3375. The RCM3365/RCM3375 may be reset by cycling the power off/on or by pressing the RESET button on the Prototyping Board. The RCM3365/RCM3375 module may now be removed from the Prototyping Board for enduse installation.

CAUTION: Disconnect power to the Prototyping Board or other boards when removing

or installing your RCM3365/RCM3375 module to protect against inadvertent shorts across the pins or damage to the RCM3365/RCM3375 if the pins are not plugged in correctly. Do not reapply power until you have verified that the RCM3365/RCM3375 module is plugged in correctly.

User’s Manual 37

4.4 Memory

4.4.1 SRAM

RCM3365/RCM3375 boards have 512K of program-execution fast SRAM at U11. The program-execution SRAM is not battery-backed. There are 512K of battery-backed data SRAM installed at U10.

4.4.2 Flash EPROM

RCM3365/RCM3375 boards also have 512K of flash EPROM at U9.

NOTE: Rabbit recommends that any customer appl ic at io ns should not be constrained by

the sector size of the flash EPROM since it may be necessary to change the sector size in the future.

Writing to arbitrary flash memory addresses at run time is also discouraged. Instead, use a portion of the “user block” area to store persistent data. The functions writeUser- Block and readUserBlock are provided for this. Refer to the Rabbit 3000 Micropro-

cessor Designer’s Handbook

information.

4.4.3 NAND Flash

The RCM3365 and the RCM3375 support a removable xD-Picture Card™ to store data and Web pages. The RCM3365 and the RCM3375 both can handle up to a 128MB removable

xD-Picture Card, and the RCM3365 model also has a 32MB onboard NAND flash.

and the Dynamic C Function Reference Manual for additional

NOTE: Rabbit-based systems do not implement the xD-Pic tu re Card™ specific ati on f o r

data storage, and are neither compatible nor compliant with xD-Picture Card™ card readers.

The NAND flash and xD-Picture Card are particularly suitable for mass-storage applica- tions, but are generally unsuitable for direct program execution. The NAND flash differs from parallel NOR flash (the type of flash memory used to store program code on Rabbitbased boards and RabbitCore modules currently in production) in two respects. First, the NAND flash requires error-correcting code (ECC) for reliability. Although NAND flash manufacturers do guarantee that block 0 will be error-free, most manufacturers guarantee that a new NAND flash chip will be shipped with a relatively small percentage of errors, and will not develop more than some maximum number or percentage of errors over its rated lifetime of up to 100,000 writes. Second, the standard NAND flash addressing method multiplexes commands, data, and addresses on the same I/O pins, while requiring that certain control lines must be held stable for the duration of the NAND flash access. The software function calls provided by Rabbit for the NAND flash take care of the dataintegrity and reliability attributes.

* RCM3365 modules sold before 2008 had 16MB fixed NAND flash memory.

38 RabbitCore RCM3365/RCM3375

Figure 10 shows how to insert or remove the x D-Picture Card. While you remove or insert

Figure 10. Insertion/Removal of xD-Picture Card

It is possible to hot-swap xD-Picture Cards without removing power from the RCM3365/ RCM3375 module. The file system must be closed before the cards can be hot-swapped. The chip selects associated with the NAND flash and the x D-Picture Card must be set to their inactive state, and read/write operations addressed to the NAND flash area cannot be allowed to occur. These operations can be initiated in software by sensing an external switch actuated by the user, and the xD-Picture Card can then be removed and replaced with a different one. Once the application program detects a new card, the file system can be opened. These steps allow the xD-Picture Card to be installed or removed without affecting either the program, which continues to run on the RCM3365/RCM3375 module, or the data stored on the xD-Picture Card.

The FAT_HOT_SWAP_336x0.C sample program in the SAMPLES\FileSystem\ folder illustrates this hot-swapping procedure.

Rabbit recommends that you use header J6 only for the xD-Picture Card since other devices are not supported. Be careful to remove and insert the xD-Picture Card as shown, and be careful not to insert any foreign objects, which may short out the contacts and lead to the destruction of your xD-Picture Card.

Sample programs in the SAMPLES\RCM3360\NANDFlash folder illustrate the use of the NAND flash. These sample programs are described in Section 3.2.1, “Use of NAND Flash.” Pay careful attention to the sample programs to see how to close files and secure any data on the xD-P icture Card before you remove it.

4.5 Other Hardware

4.5.1 Clock Doubler

The RCM3365/RCM33610 takes advantage of the Rabbit 3000 microprocessor’s internal clock doubler. A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emissions. The 44.2 MHz frequency specified for the RCM3365/RCM3375 is generated using a 22.12 MHz resonator.

The clock doubler may be disabled if 44.2 MHz clock speeds are not required. This will reduce power consumption and further reduce radiated emissions. The clock doubler is disabled with a simple configuration macro as shown below.

1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.

2. Add the line CLOCK_DOUBLED=0 to always disable the clock doubler. The clock doubler is enabled by default, and usually no entry is needed. If you need to

specify that the clock doubler is always enabled, add the line CLOCK_DOUBLED=1 to always enable the clock doubler.

3. Click OK to save the macro. The clock doubler will now remain off whenever you are in the project file where you defined the macro.

4.5.2 Spectrum Spreader

The Rabbit 3000 features a spectrum spreader, which helps to mitigate EMI problems. The spectrum spreader is on by default, but it may also be turned off or set to a stronger setting. The means for doing so is through a simple configuration macro as shown below.

1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.

2. Normal spreading is the default, and usually no entry is needed. If you need to specify normal spreading, add the line

ENABLE_SPREADER=1

For strong spreading, add the line

ENABLE_SPREADER=2

To disable the spectrum spreader, add the line

ENABLE_SPREADER=0

5. SOFTWARE REFERENCE

Dynamic C is an integrated development system for writing embedded software. It runs on an IBM-compatible PC and is designed for use with Rabbit controllers and other controllers based on the Rabbit microprocessor. Chapter 5 describes the libraries and function calls related to the RCM3365/RCM3375.

5.1 More About Dynamic C

Dynamic C has been in use worldwide since 1989. It is specially designed for programming embedded systems, and features quick compile and interactive debugging. A complete reference guide to Dynamic C is contained in the Dynamic C User’s Manual.

You have a choice of doing your software development in the flash memory or in the static SRAM included on the RCM3365/RCM3375. The flash memory and SRAM options are selected with the Options > Program Options > Compiler menu.

The advantage of working in RAM is to save wear on the flash memory, which is limited to about 100,000 write cycles. The disadvantage is that the code and data might not both fit in RAM.

NOTE: An application should be run from the program execution SRAM after the serial

programming cable is disconnected. Your final code must always be stored in flash memory for reliable operation. RCM3365/RCM3375 modules running at 44.2 MHz have a fast program execution SRAM that is not battery-backed. Select

BIOS in Flash, Run in RAM Compiler

SRAM at run-time to take advantage of the faster clock speed. This option optimizes the performance of RCM3365/RCM3375 modules running at 44.2 MHz.

NOTE: Do not depend on the flash memory sector size or type in your program logic.

The RCM3365/RCM3375 and Dynamic C were designed to accommodate flash devices with various sector sizes in response to the volatility of the flash-memory market.

Developing software with Dynamic C is simple. Users can write, compile, and test C and assembly code without leaving the Dynamic C development environment. Debugging occurs while the application runs on the target. Alternatively, users can compile a program to an image file for later loading. Dynamic C runs on PCs under Windows 2000/NT and

later—see Rabbit’s Technical Note TN257, Running Dynamic C® With Windows Vista®,

for additional information if you are using a Dynamic C release prior to v. 9.60 under Windows Vista. Programs can be downloaded at baud rates of up to 460,800 bps after the program compiles.

Dynamic C has a number of standard features.

• Full-feature source and/or assembly-level debugger, no in-circuit emulator required.

• Royalty-free TCP/IP stack with source code and most common protocols.

• Hundreds of functions in source-code libraries and sample programs:

X Exceptionally fast support for floating-point arithmetic and transcendental functions. X RS-232 and RS-485 serial communication. X Analog and digital I/O drivers.

X I

C, SPI, GPS, file system.

X LCD display and keypad drivers.

• Powerful language extensions for cooperative or preemptive multitasking

• Loader utility program to load binary images into Rabbit targets in the absence of

Dynamic C.

• Provision for customers to create their own source code libraries and augment on-line help by creating “function description” block comments using a special format for library functions.

• Standard debugging features:

X Breakpoints—Set breakpoints that can disable interrupts. X Single-stepping—Step into or over functions at a source or machine code level, µC/OS-II aware. X Code disassembly—The disassembly window displays addresses, opcodes, mnemonics, and

machine cycle times. Switch between debugging at machine-code level and source-code level by simply opening or closing the disassembly window.

X Watch expressions—Watch expressions are compiled when defined, so complex expressions

including function calls may be placed into watch expressions. Watch expressions can be updated with or without stopping program execution.

X Register window—All processor reg isters and f lags are disp layed. The con tents of gener al register s

may be modified in the window by the user.

X Stack window—shows the contents of the top of the stack. X Hex memory dump—displays the contents of memory at any address. X STDIO window—

detected for debugging purposes.

printf outputs to this window and keyboard input on the host PC can be

printf output may also be sent to a serial port or file.

5.1.1 Developing Programs Remotely with Dynamic C

Dynamic C is an integrated development environment that allows you to edit, compile, and debug your programs. Dynamic C has the ability to allow programming over the Internet or local Ethernet. This is accomplished in one of three ways.

1. RCM3365 RabbitCore modules that are preloaded with Dynamic C RabbitSys firmware can be used with Dynamic C RabbitSys to be accessed via an Ethernet connection for remote application updates, and for remote monitoring and control. Dynamic C RabbitSys requires Dynamic C version 9.30 or later, and allows the RCM3365. The Dynamic C RabbitSys User’s Manual provides complete information on RabbitSys.

2. Via the Rabbit RabbitLink, which allows a Rabbit-based target to have programs downloaded to it and debugged with the same ease as exists when the target is connected directly to a PC.

3. Dynamic C provides sample programs to illustrate the use of a download manager, but these sample programs are not intended for use with the NAND flash on the RCM3365 and RCM3375 RabbitCore modules. The grams found in the Dynamic C

SAMPLES\DOWN_LOAD

DLM_TCP.C

and

DLP_TCP.C

sample pro-

folder, are intended to be compiled to the program flash memory (which is a parallel flash memory). Custom applications based on these sample programs may use the NAND flash for data storage.

User’s Manual 43

5.2 Dynamic C Functions

5.2.1 Digital I/O

The RCM3365/RCM3375 was designed to interface with other systems, and so there are no drivers written specifically for the I/O. The general Dynamic C read and write functions allow you to customize the parallel I/O to meet your specific needs. For example, use

WrPortI(PEDDR, &PEDDRShadow, 0x00);

to set all the Port E bits as inputs, or use

WrPortI(PEDDR, &PEDDRShadow, 0xFF);

to set all the Port E bits as outputs. When using the external I/O bus on the Rabbit 3000 chip, add the line

#define PORTA_AUX_IO // required to enable external I/O bus

to the beginning of any programs using the external I/O bus. The sample programs in the Dynamic C

SAMPLES/RCM3360

folder provide further

examples.

5.2.2 SRAM Use

The RCM3365/RCM3375 have a battery-backed data SRAM and a program-execution SRAM. Dynamic C provides the

protected

keyword to identify variables that are to be placed into the battery-backed SRAM. The compiler generates code that maintains two copies of each protected variable in the battery-backed SRAM. Th e compiler also gene rates a flag to ind icat e whic h copy of the protected variable is valid at the current time. This flag is also stored in the battery-backed SRAM. When a protected variable is updated, the “inactive” copy is modified, and is made “active” only when the update is 100% complete. This assures the integrity of the data in case a reset or a power failure occurs during the update process. At power-on the application program uses the active copy of the variable pointed to by its associated flag.

The sample code below shows how a protected variable is defined and how its value can be restored.

protected nf_device nandFlash;

int main() { ...

_sysIsSoftReset(); // restore any protected variables

The

bbram

keyword may also be used instead if there is a need to store a variable in bat-

tery-backed SRAM without affecting the performance of the application program. Data integrity is not assured when a reset or power failure occurs during the update process.

Additional information on

bbram

and

protected

variables is available in the Dynamic C

User’s Manual.

5.2.3 Serial Co mmunication Drivers

Library files included with Dynamic C provide a full range of serial communications support. The

PACKET.LIB

RS232.LIB

library provides packet-based serial functions where packets can be delimited

library provides a set of circular-buffer-based serial functions. The

by the 9th bit, by transmission gaps, or with user-defined special characters. Both libraries provide blocking functions, which do not return until they are finished transmitting or receiving, and nonblocking functions, which must be called repeatedly until they are finished, allowing other functions to be performed between calls. For more information, see the Dynamic C Function Reference Manual and Technical Note TN213, Rabbit Serial Port Software.

5.2.4 TCP/IP Drivers

The TCP/IP drivers are located in the

LIB\TCPIP

folder. Complete information on these

libraries and the TCP/IP functions is provided in the Dynamic C TCP/IP User’s Manual.

5.2.5 NAND Flash Drivers

The Dynamic C

NANDFlash\NFLASH.LIB

library is used to interface to NAND flash memory devices on the RCM3365 and the RCM33 75. The function calls were written specifically to work with industry-standard flash devices with a 528-byte page program and 16896-byte block erase size. The NAND flash function calls are designed to be closely cross-compatible with the newer serial flash function calls found in the library . These function calls use an

nf_device

structure as a handle for a specific NAND

SFLASH.LIB

flash device. This allows multiple NAND flash devices to be used by an application. More information on these function calls is available in the Dynamic C Function Refer-

ence Manual. The NAND flash and the xD-Picture Card are ideally suited to store files with a directory

structure. The Dynamic C FAT file system module provides support for a file system and for formatting the xD-Picture Car d for use in a Rabbit-bas ed system. Visit our W eb site at

www.rabbit.com or contact your Rabbit sales representative or authorized distributor for

further information on the Dynamic C FAT File System and other Dynamic C modules. The supporting documentation for the Dynamic C FAT File System and the sample programs in the SAMPLES\FileSystem\ folder illustrate the use of the Dynamic C FAT file system.

User’s Manual 45

5.2.6 Prototyping Board Functions

6. USING THE TCP/IP FEATURES

6.1 TCP/IP Connections

Programming and development can be done with the RCM3365/RCM3375 modules without connecting the Ethernet port to a network. However, if you will be running the sample programs that use the Ethernet capability or will be doing Ethernet-enabled development, you should connect the RCM3365/RCM3375 module’s Ethernet port at this time.

Before proceeding you will need to have the following items.

• If you don’t have Ethernet access, you will need at least a 10Base-T Ethernet card (available from your favorite computer supplier) installed in a PC.

• Two RJ-45 straight-through Ethernet cables and a hub, or an RJ-45 crossover Ethernet cable.

A straight-through and a crossover Ethernet cable are included in the RCM3365/RCM3 375 Development Kit. Figure 11 shows how to identify the two cables based on the wires in the transparent RJ-45 connectors.

Crossover

Cable

Now you should be able to make your connections.

1. Connect the AC adapter and the serial programming cable as shown in Chapter 2, “Getting Started.”

2. Ethernet Connections There are four options for connecting the RCM3365/RCM3375 module to a network

for development and runtime purposes. The first two options permit total freedom of action in selecting network addresses and use of the “network,” as no action can interfere with other users. We recommend one of these options for initial development.

No LAN — The simplest alternative for desktop development. Connect the

•

RCM3365/RCM3375 module’s Ethernet port directly to the PC’s network interface card using an RJ-45 crossover cable. A crossover cable is a special cable that flips some connections between the two connectors and permits direct connection of two client systems. A standard RJ-45 network cable will not work for this purpose.

• Micro-LAN — Another simple alternative for desktop development. Use a small Ethernet 10Base-T hub and connect both the PC’s network interface card and the RCM3365/RCM3375 module’s Ethernet port to it using standard network cables.

The following options require more care in address selection and testing actions, as conflicts with other users, servers and systems can occur:

• LAN — Connect the RCM3365/RCM3375 module’s Ethernet port to an existing LAN, preferably one to which the development PC is already connected. You will need to obtain IP addressing information from your network administrator.

• WAN — The RCM3365/RCM3375 is capable of direct connection to the Internet and other Wide Area Networks, but exceptional care should be used with IP address settings and all network-related programming and development. We recommend that development and debugging be done on a local network before connecting a RabbitCore system to the Internet.

TIP: Checking and debugging the initial setup on a micro-LAN is recommended before

connecting the system to a LAN or WAN.

The PC running Dynamic C does not need to be the PC with the Ethernet card.

3. Apply Power Plug in the AC adapter. The RCM3365/RCM3375 module and Prototyping Board are

now ready to be used.

6.2 TCP/IP Primer on IP Addresses

Obtaining IP addresses to interact over an existing, operating, network can involve a number of complications, and must usually be done with cooperation from your ISP and/or network systems administrator. For this reason, it is suggested that the user begin instead by using a direct connection between a PC and the RCM3365/RCM3375 using an Ethernet crossover cable or a simple arrangement with a hub. (A crossover cable should not be confused with regular straight through cables.)

In order to set up this direct connection, the user will have to use a PC without networking, or disconnect a PC from the corporate network, or install a second Ethernet adapter and set up a separate private network attached to the second Ethernet adapter. Disconnecting your PC from the corporate network may be easy or nearly impossible, depending on how it is set up. If your PC boots from the network or is dependent on the network for some or all of its disks, then it probably should not be disconnected. If a second Ethernet adapter is used, be aware that Windows TCP/IP will send messages to one adapter or the other, depending on the IP address and the binding order in Microsoft products. Thus you should have different ranges of IP addresses on your private network from those used on the corporate network. If both networks service the same IP address, then Windows may send a packet intended for your private network to the corporate network. A similar situation will take place if you use a dial-up line to send a packet to the Internet. Windows may try to send it via the local Ethernet network if it is also valid for that network.

The following IP addresses are set aside for local networks and are not allowed on the Internet: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to

192.168.255.255. The RCM3365/RCM3375 uses a 10/100Base-T type of Ethernet connection, which is the

most common scheme. The RJ-45 connectors are similar to U.S. style telephone connectors, except they are larger and have 8 contacts.

An alternative to the direct connection using a crossover cable is a direct connection using a hub. The hub relays packets received on any port to all of the ports on the hub. Hubs are low in cost and are readily available. The RCM3365/RCM3375 uses 10/100 Mbps Ethernet, so the hub or Ethernet adapter can be a 10 Mbps unit, a 100 Mbps unit, or a 10/100 Mbps unit.

In a corporate setting where the Internet is brought in via a high-speed line, there are typically machines between the outside Internet and the internal network. These machines include a combination of proxy servers and firewalls that filter and multiplex Internet traffic. In the configuration below, the RCM3365/RCM3375 could be given a fixed address so any of the computers on the local network would be able to contact it. It may be possible to configure the firewall or proxy server to allow hosts on the Internet to directly contact the controller, but it would probably be easier to place the controller directly on the external network outside of the firewall. This avoids some of the configuration complications by sacrificing some security.

If your system administrator can give you an Ethernet cable along with its IP address, the netmask and the gateway address, then you may be able to run the sample programs without having to setup a direct connection between your computer and the RCM3365/ RCM3375. You will also need the IP address of the nameserver, the name or IP address of your mail server, and your domain name for some of the sample programs.

56 RabbitCore RCM3365/RCM3375

6.2.1 IP Addresses Explained

IP (Internet Protocol) addresses are expressed as 4 decimal numbers separated by periods, for example:

216.103.126.155

10.1.1.6

Each decimal number must be between 0 and 255. The total IP address is a 32-bit number consisting of the 4 bytes expressed as shown above. A local network uses a group of adja-

cent IP addresses. There are always 2

IP addresses in a local network. The netmask (also called subnet mask) determines how many IP addresses belong to the local network. The netmask is also a 32-bit address expressed in the same form as the IP address. An example netmask is:

255.255.255.0

This netmask has 8 zero bits in the least significant portion, and this means that 28 addresses are a part of the local network. Applied to the IP address above (216.103.126.155), this netmask would indicate that the following IP addresses belong to the local network:

216.103.126.0

216.103.126.1

216.103.126.2 etc.

216.103.126.254

216.103.126.255

The lowest and highest address are reserved for special purposes. The lowest address (216.102.126.0) is used to identify the local network. The highest address (216.102.126.255) is used as a broadcast address. Usually one other address is used for the address of the gateway out of the network. This leaves 256 - 3 = 253 available IP addresses for the example given.

User’s Manual 57

6.2.2 How IP Addresses are Used

The actual hardware connection via an Ethernet uses Ethernet adapter addresses (also called MAC addresses). These are 48-bit addresses and are unique for every Ethernet adapter manufactured. In order to send a packet to another computer, given the IP address of the other computer, it is first determined if the packet needs to be sent directly to the other computer or to the gateway. In either case, there is an Ethernet address on the local network to which the packet must be sent. A table is maintained to allow the protocol driver to determine the MAC address corresponding to a particular IP address. If the table is empty, the MAC address is determined by sending an Ethernet broadcast packet to all devices on the local network asking the device with the desired IP address to answer with its MAC address. In this way, the table entry can be filled in. If no device answers, then the device is nonexistent or inoperative, and the packet cannot be sent.

Some IP address ranges are reserved for use on internal networks, and can be allocated freely as long as no two internal hosts have the same IP address. These internal IP addresses are not routed to the Internet, and any internal hosts using one of these reserved IP addresses cannot communicate on the external Internet without being connected to a host that has a valid Internet IP address. The host would either translate the data, or it would act as a proxy.

Each RCM3365/RCM3375 RabbitCore module has its own unique MAC address, which consists of the prefix 0090C2 followed by a code that is unique to each RCM3365/ RCM3375 module. For example, a MAC address might be 0090C2C002C0.

TIP: You can always obtain the MAC address on your board by running the sample pro-

gram DISPLAY_MAC.C from the SAMPLES\TCPIP folder.

58 RabbitCore RCM3365/RCM3375

6.2.3 Dynamically Assigned Internet Addresses

In many instances, devices on a network do not have fixed IP addresses. This is the case when, for example, you are assigned an IP address dynamically by your dial-up Internet service provider (ISP) or when you have a device that provides your IP addresses using the Dynamic Host Configuration Protocol (DHCP). The RCM3365/RCM3375 modules can use such IP addresses to send and receive packets on the Internet, but you must take into account that this IP address may only be valid for the duration of the call or for a period of time, and could be a private IP address that is not directly accessible to others on the Internet. These addresses can be used to perform some Internet tasks such as sending e-mail or browsing the Web, but it is more difficult to participate in conversations that originate elsewhere on the Internet. If you want to find out this dynamically assigned IP address, under Windows 98 you can run the

winipcfg program while you are connected

and look at the interface used to connect to the Internet. Many networks use IP addresses that are assigned using DHCP. When your computer

comes up, and periodically after that, it requests its networking information from a DHCP server. The DHCP server may try to give you the same address each time, but a fixed IP address is usually not guaranteed.

If you are not concerned about accessing the RCM3365/RCM3375 from the Internet, you can place the RCM3365/RCM3375 on the internal network using an IP address assigned either statically or through DHCP.

User’s Manual 59

6.3 Placing Your Device on the Network

In many corporate settings, users are isolated from the Internet by a firewall and/or a proxy server. These devices attempt to secure the company from unauthorized network traffic, and usually work by disallowing traffic that did not originate from inside the network. If you want users on the Internet to communicate with your RCM3365/RCM3375, you have several options. You can either place the RCM3365/RCM3375 directly on the Internet with a real Internet address or place it behind the firewall. If you place the RCM3365/RCM3375 behind the firewall, you need to configure the firewall to translate and forward packets from the Internet to the RCM3365/RCM3375.

We have provided a num ber of samp le pr ograms de mons trat ing va rious us es of TCP/ IP for networking embedded systems. These programs require you to connect your PC and the RCM3365/RCM3375 board together on the same network. This network can be a local private network (preferred for initial experimentation and debugging), or a connection via the Internet.

The sample programs described in this chapter may also be run with a RabbitSys-enabled RCM3365 operating in the RabbitSys mode. There is no change to the instructions when you use the serial programming cable. When you use an Ethernet cable, you may use CAT 5/6 straight-through Ethernet cables to connect the RCM3365 and your PC to a DHCP network. It is not necessary to use a crossover cable for a direct connection. Use the TCP/IP parameters such as the IP address that you identified with the rdiscover utility; if you are using an Ethernet crossover cable to connect the RCM3365 directly to your PC, use the TCP/IP parameters that you set up according to the instructions in Appendix E.

6.4.1 How to Set IP Addresses in the Sample Programs

With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run many of our sample programs. You will see a TCPCONFIG macro. This macro tells Dynamic C to select your configuration from a list of default configurations. You will have three choices when you encounter a sample program with the TCPCONFIG macro.

1. You can replace the

MASK

, MY_GATEWAY, and MY_NAMESERVER macros in each program.

TCPCONFIG macro with individual MY_IP_ADDRESS, MY_NET-

2. You can leave TCPCONFIG at the usual default of 1, which will set the IP configurations to 10.10.6.100, the netmask to 255.255.255.0, and the nameserver and gateway to 10.10.6.1. If you would like to change the default values, for example, to use an IP address of 10.1.1.2 for the RCM3365/RCM3375 board, and 10.1.1.1 for your PC, you can edit the values in the section that directly follows the “General Configuration” comment in the TCP_CONFIG.LIB library. Yo u will find this library in the LIB\TCPIP directory.

3. You can create a CUSTOM_CONFIG.LIB library and use a TCPCONFIG value greater than 100. Instructions for doing this are at the beginning of the TCP_CONFIG.LIB library in the LIB\TCPIP directory.

There are some other “standard” configurations for TCPCONFIG that let you select different features such as DHCP. Their values are documented at the top of the TCP_CON-

FIG.LIB

library in the LIB\TCPIP directory. More information is available in the

Dynamic C TCP/IP User’s Manual.

6.4.2 How to Set Up your Computer for Direct Connect

TIP: If you are using a PC that is already on a network, you will disconnect the PC from

that network to run these sample programs. Write down the existing settings before changing them to facilitate restoring them when you are finished with the sample programs and reconnect your PC to the network.

1. Go to the control panel (Start > Settings > Control Panel), and then double-click the Network icon.

2. Select the network interface card used for the Ethernet interface you intend to use (e.g.,

TCP/IP Xircom Credit Card Network Adapter) and click on the “Properties” button.

Depending on which version of Windows your PC is running, you may have to select the “Local Area Connection” first, and then click on the “Properties” button to bring up the Ethernet interface dialog. Then “Configure” your interface card for a “10Base-T Half-Duplex” or an “Auto-Negotiation” connection on the “Advanced” tab.

NOTE: Your network interface card will likely have a different name.

IP Address : 10.10.6.101 Netmask : 255.255.255.0 Default gateway : 10.10.6.1

4. Click <OK> or <Close> to exit the various dialog boxes.

6.5 Run the PINGME.C Sample Program

Connect the crossover cable from your computer’s Ethernet port to the RCM3365/ RCM3375 board’s RJ-45 Ethernet connector. Open this sample program from the

SAMPLES\TCPIP\ICMP folder, compile the program, and start it running under Dynamic C.

The crossover cable is connected from your computer’s Ethernet adapter to the RCM3365/ RCM3375 board’s RJ-45 Ethernet connector. When the program starts running, the green

LINK light on the RCM3365/RCM3375 module should be on to indicate an Ethernet con-

nection is made. (Note: If the LNK light does not light, you may not be using a crossover cable, or if you are using a hub with straight-through cables perhaps the power is off on the hub.)

The next step is to ping the board from your PC. This can be done by bringing up the MSDOS window and running the pingme program:

ping 10.10.6.101

or by Start > Run and typing the entry

ping 10.10.6.101

Notice that the yellow ACT light flashes on the RCM3365/RCM3375 module while the ping is taking place, and indicates the transfer of data . The ping routine will ping the board four times and write a summary message on the screen describing the operation.

6.6 Running Additional Sample Programs With Direct Connect

The following sample programs are in the Dynamic C SAMPLES\RCM3360\TCPIP\ folder.

• BROWSELED.C—This program demonstrates a basic controller running a Web page. Two “device LEDs” are created along with two buttons to toggle them. Users can use their Web browser to change the status of the lights. The DS3 and DS4 LEDs on the Prototyping Board will match those on the W eb page. As long as you have not modified the TCPCONFIG 1 macro in the sample program, enter the following server address in your Web browser to bring up the Web page served by the sample program.

http://10.10.6.100.

Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library.

• MBOXDEMO.C—The optional LCD/keypad module (see Appendix C) must be plugged in to the Prototyping Board when using this sample program. This program demonstrates sending e-mail messages that are then shown on the LCD/keypad module display. The keypad is used to scroll through a menu to view the messages, flip to other messages, mark messages as read, and delete messages. When a new e-mail arrives, an LED on the LCD/keypad module turns on, and then turns off once the message has been marked as read. A log of all e-mail actions is kept, and can be displayed in the Web browser. All current e-mails can also be read with the Web browser.

64 RabbitCore RCM3365/RCM3375

• PINGLED.C—This program demonstrates ICMP by pinging a remote host. It will flash LEDs DS3 and DS4 on the Prototyping Board when a ping is sent and received.

• SMTP.C—This program demonstrates using the SMTP library to send an e-mail when the S2 and S3 switches on the Prototyping Board are pressed. LEDs DS3 and DS4 on the Prototyping Board will light up when e-mail is being sent.

6.6.1 RabbitWeb Sample Programs

You will need to have the Dynamic C RabbitWeb module installed before you run the sample programs described in this section. The following sample programs are in the Dynamic C SAMPLES\RCM3360\TCPIP\RABBITWEB folder.

• BLINKLEDS.C—This program demonstrates a basic example to change the rate at which the DS3 and DS4 LEDs on the Prototyping Board blink.

• DOORMONITOR.C—The optional LCD/keypad module (see Appendix C) must be plugged in to the Prototyping Board when using this sample program. This program demonstrates adding and monitoring passwords entered via the LCD/keypad module.

• SPRINKLER.C—This program demonstrates how to schedule times for the relay and digital outputs in a 24-hour period.

6.7 Where Do I Go From Here?

NOTE: If you purchased your RCM3365/RCM3375 through a distributor or through a

Rabbit partner, contact the distributor or partner first for technical support.

If the sample programs ran fine, you are now ready to go on. Additional sample programs are described in the Dynamic C TCP/IP User’s Manual. Please refer to the Dynamic C TCP/IP User’s Manu al to develop your own applications.

APPENDIX B. PROTOTYPING BOARD

Appendix B describes the features and accessories of the Prototyping Board.

User’s Manual 81

B.1 Introduction

The Prototyping Board included in the Development Kit makes it easy to connect an RCM3365/RCM3375 module to a power supply and a PC workstation for development. It also provides some basic I/O peripherals (RS-232, RS-485, a relay, LEDs, and switches), as well as a prototyping area for more advanced hardware development.

For the most basic level of evaluation and development, the Prototyping Board can be used without modification.

As you progress to more sophisticated experimentation and hardware development, modifications and additions can be made to the board without modifying or damaging the RCM3365/RCM3375 module itself.

The Prototyping Board is shown below in Figure B-1, with its main features identified.

Figure B-1. Prototyping Board

82 RabbitCore RCM3365/RCM3375

B.1.1 Prototyping Board Features

• Power Connection—A power-supply jack and a 3-pin header are provided for connection to the power supply. Note that the 3-pin header is symmetrical, with both outer pins connected to ground and the center pin connected to the raw V+ input. The cable of the AC adapter provided with the North American version of the Development Kit ends in a plug that connects to the power-supply jack (J1). A header plug leading to bare leads is provided for overseas customers to connect their power supply to the 3-pin header (J2)—the center pin of J2 is always connected to the positive terminal, and either edge pin is negative.

Users providing their own power supply should ensure that it delivers 8–30 V DC at 1 A.

Regulated Power Supply—The raw DC voltage provided at the POWER IN jack is

•

routed to a 5 V switching voltage regulator, then to a separate 3.3 V linear regulator. The regulators provide stable power to the RCM3365/RCM3375 module and the Prototyping Board. The voltage regulators will get warm while in use.

• Power LED—The power LED lights whenever power is connected to the Prototyping Board.

• Core LED—The core LED lights whenever an RCM3365/RCM3375 module is plugged in correctly on the Prototyping Board and the RCM3365/RCM3375 module is not being reset.

• Relay LED—The relay LED lights whenever the Prototyping Board relay is energized.

• Reset Switch—A momentary-contact, normally open switch is connected directly to the

RCM3365/RCM3375’s /RESET_IN pin. Pressing the switch forces a hardware reset of the system.

• I/O Switches and LEDs—Two momentary-contact, normally open switches are connected to the PG0 and PG1 pins of the RCM3365/RCM3375 module and may be read as inputs by sample applications.

Four user LEDs (DS3–DS6) are connected to alternate I/O bus pins PA0–PA3 pins of the RCM3365/RCM3375 module via U8, and may be driven as output indicators. PE7 and PG5 control the registers in U8 as shown in the sample applications.

• Prototyping Area—A generous prototyping area has been provided for the installation of through-hole components. +3.3 V, +5 V, and Ground buses run along one edge of this area. Several areas for surface-mount devices are also available. Each SMT pad is connected to a hole designed to accept a 30 AWG solid wire.

• LCD/Keypad Module—Rabbit’s LCD/keypad module may be plugged in directly to

headers LCD1JA, LCD1JB, and LCD1JC. The signals on headers LCD1JB and LCD1JC will be available only if the LCD/keypad module is plugged in to header LCD1JA. Appendix C provides complete information for mounting and using the LCD/keypad module.

User’s Manual 83

• Module Extension Headers—The complete pin set of the RCM3365/RCM3375 module is duplicated at headers J8 and J9. Developers can solder wires directly into the appropriate holes, or, for more flexible development, 2 × 17 header strips with a 0.1" pitch can be soldered into place. See Figure B-4 for the header pinouts.

• Digital I/O—Four digital inputs are available on screw-terminal header J6. See

Figure B-4 for the header pinouts.

RS-232—Two 3-wire serial ports or one 5-wire RS-232 serial port are available on the

•

Prototyping Board at screw-terminal header J14.

• RS-485—One RS-485 serial port is available on the Prototyping Board at screw-terminal header J14.

• Quadrature Decoder—Four quadrature decoder inputs (PF0–PF3) from the Rabbit 3000 chip are available on screw-terminal header J5. See Figure B-4 for the header pinouts.

• H-Bridge Motor Driver—Two pairs of H-bridge motor drivers are supported using screw-terminal headers J3 and J4 on the Prototyping Board for stepper-motor control. See Figure B-4 for the header pinouts.

• RabbitNet Port—One RS-422 RabbitNet port (shared with the serial flash interface) is available to allow RabbitNet peripheral cards to be used with the RCM3365/RCM3375 and the Prototyping Board.

• Serial Flash Interface—One serial flash interface (shared with the RabbitNet port) is

available to allow Rabbit’s SF1000 series serial flash to be used on the Prototyping Board.

B.3 Power Supply

The RCM3365/RCM3375 requires a regulated 3.15 V to 3.45 V DC power source to operate. Depending on the amount of current required by the application, different regulators can be used to supply this voltage.

The Prototyping Board has an onboard +5 V switching power regulator from which a +3.3 V linear regulator draws its supply. Thus both +5 V and +3.3 V are available on the Prototyping Board.

The Prototyping Board itself is protected against reverse polarity by a diode at D1 as shown in Figure B-3.

The Prototyping Board comes with the basic components necessary to demonstrate the operation of the RCM3365/RCM3375. Four user LEDs (DS3–DS6) are connected to alternate I/O bus pins P A0–PA3 pins of the RCM3365/RCM3375 module via U8, and may be driven as output indicators when controlled by PE7 and PG5 as shown in the sample applications. Two switches (S2 and S3) are connected to PG0 and PG1 to demonstrate the interface to the Rabbit 3000 microprocessor. Reset switch S1 is the hardware reset for the RCM3365/RCM3375.

Prototyping Board provides the user with RCM3365/RCM3375 connection points

The brought out conveniently to labeled points at J8 and J9 on the Prototyping Boa rd. Although locations J8 and J9 are unstuffed, 2 × 17 headers are included in the bag of parts.

RS-232 and RS-485 signals are available on screw-terminal header J14, quadrature decoder inputs are available on screw-terminal header J5, and digital inputs are available on screw-terminal header J6. A 1 × 5 header strip from the bag of parts may be installed at J12 for four sinking digital outputs. A 1 × 3 header strip from the bag of parts may be installed at J13 to access selected signals from RCM3000, RCM3100, RCM3200, RCM3300/RCM3310, and RCM3365/RCM3375 RabbitCore modules (J13 cannot be used with the RCM3305/RCM3315).

If you don’t plan to use the LCD/keypad module, additional signals may be brought out on 1 × 5 and 1 × 8 headers from the bag of parts that you install at J15 and J 16. If you don’ t plan t o use the stepper-motor control option, additional CMOS outputs are available via a 1 × 8 header that you install at J10.

There is a through-hole prototyping space available on the Prototyping Board. the prototyping area are spaced at 0.1" (2.5 mm). one edges of the

prototyping area. Small to medium circuits can be prototyped using point-

+3.3 V, +5 V, and GND traces run along

to-point wiring with 20 to 30 A WG wire between the prototyping area, the GND traces,

and the surrounding area where surface-mount components may be installed.

The holes in

+3.3 V, +5 V , and

Small holes are provided around the surface-mounted components that may be installed around the prototyping area.

B.4.1 Adding Other Components

There are two sets of pads for 6-pin, 16-pin, and 28-pin devices that can be used for surface-mount prototyping devices. There are also pads that can be used for SMT resistors and capacitors in an 0805 SMT package. Each component has every one of its pin pads connected to a hole in which a 30 A WG wire can be soldered (standard wire wrap wire can be soldered in for point-to-point wiring on the Prototyping Board). Because the traces are very thin, carefully determine which set of holes is connected to which surface-mount pad.

The four quadrature decoder inputs on screw-terminal header J5 may be used as inputs IN4–IN7. To use the PF0 signal from the Rabbit microprocessor, which goes to QD1B, remember to reconfigure the jumper on header JP3 to jumper pins 1–2.

The actual switching threshold is between 0.9 V and 2.3 V. Anything below this value is a logic 0, and anything above is a logic 1.

The digital inputs are each fully protected over a range of -36 V to +36 V, and can handle short spikes of ±40 V.

92 RabbitCore RCM3365/RCM3375

B.4.6.1 RS-232

RS-232 serial communication on the Prototyping Board is supported by an RS-232 transceiver installed at U9. This transceiver provides the voltage output, slew rate, and input voltage immunity required to meet the RS-232 serial communication protocol. Basically, the chip translates the Rabbit 3000’s signals to RS-232 signal levels. Note that the polarity is reversed in an RS-232 circ uit so that a +5 V output becomes approximately -10 V and 0 V is output as +10 V. The RS-232 transceiver also provides the proper line loading for reliable communication.

RS-232 can be used effectively at the RCM3365/RCM3375 module’s maximum baud rate for distances of up to 15 m.

RS-232 flow control on an RS-232 port is initiated in software using the

serXflowcontrolOn function call from RS232.LIB, where X is the serial port (E or F).

The locations of the flow control lines are specified using a set of five macros.

SERX_RTS_PORT—Data register for the parallel port that the RTS line is on (e.g., PGDR). SERX_RTS_SHADOW—Shadow register for the RTS line's parallel port (e.g., PGDRShadow). SERX_RTS_BIT—The bit number for the RTS line. SERX_CTS_PORT—Data register for the parallel port that the CTS line is on (e.g., PCDRShadow). SERX_CTS_BIT—The bit number for the CTS line.

Standard 3-wire RS-232 communication using Serial Ports E and F i s il lustrated in the following sample code.

#define EINBUFSIZE 15 // set size of circular buffers in bytes #define EOUTBUFSIZE 15

#define FINBUFSIZE 15 #define FOUTBUFSIZE 15

#define MYBAUD 115200 // set baud rate #endif

main(){ serEopen(_MYBAUD); // open Serial Ports E and F serFopen(_MYBAUD); serEwrFlush(); // flush their input and transmit buffers serErdFlush(); serFwrFlush(); serFrdFlush(); serEclose(_MYBAUD); // close Serial Ports C and D serFclose(_MYBAUD); }

User’s Manual 93

B.4.6.2 RS-485

The Prototyping Board has one RS-485 serial channel, which is connected to the Rabbit 3000 Serial Port C through an RS-485 transceiver. The half-duplex communication uses an output from PD7 on the Rabbit 3000 to control the transmit enable on the communication line. Using this scheme a strict master/slave relationship must exist between devices to insure that no two devices attempt to drive the bus simultaneously.

Serial Port C is configured in software for RS-485 as follows.

The configuration shown above is based on circular buffers. RS-485 configuration may also be done using functions from the PACKET.LIB library.

The Prototyping Boards with RCM3365/RCM3375 modules installed can be used in an RS-485 multidrop network spanning up to 1200 m (4000 ft), and there can be as many as 32 attached devices. Connect the 485+ to 485+ and 485– to 485– using single twisted-pair wires as shown in Figure B-8. Note that a common ground is recommended.
