Rabbit RCM5700, RCM6700 User Manual

Run a Sample Program

Find the file PONG.C, which is in the Dynamic C SAMPLES f older. To run the program, open it with
the File menu, compile it using the Compile menu, and then run it by selecting Run in the Run menu.
The STDIO window will open on your PC and will display a small square bouncing around in a box.

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 RCM5700/6700 User’s Manual also provides complete
hardware reference information for the RCM5700/6700, the Interface Board, the Prototyping
Board, and the accessory boards in the Deluxe Development Kit. The Dynamic C User’s Manual
provides complete information about Dynamic C.

Troubleshooting

If you receive the message Could Not Open Serial Port, check that the COM port
assigned to the USB cable was identified and set up in Dynamic C as described above.

If you receive the message No Rabbit Processor Detected, the USB cable may be
connected to the wrong COM port, or the connection may be faulty. First, check both ends of
the USB cable to ensure they are firmly plugged into the PC and the USB connector in the
Interface Board. Ensure that the module is correctly installed in its connector on the Interface
Board.

If Dynamic C appears to compile the BIOS successfully, but you then receive a communication
error message when you compile and load a 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 on the “Communications” tab in the Dynamic C Options >

Project Options 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.

MiniCore RCM5700/6700

The RCM5700 and RCM6700 modules provide a compact module in a mini PCI Express form factor
with integrated 10/100Base-T Ethernet functionality. These Getting Started instructions included
with the Development Kit will help you get your MiniCore up and running so that you can run the
sample programs to explore its capabilities and develop your own applications.

Development Kit Contents

For drivers, documentation, and development software and sample code, go to:

www.digi.com/support/RabbitDynamicC .

The RCM5700 and RCM6700 Standard Development Kits contain the following items:

• RCM5700 module or RCM6700 module (depending on the kit).

• Interface Board with standoffs/connectors.

• Prototyping Board with standoffs/connectors.

• Locate the Serial Options dialog on the “Communications” tab in the Dynamic C Options >

Project Options menu. Choose a lower debug baud rate.

• Press <Ctrl-Y> to force Dynamic C to recompile the BIOS. You should receive a Bios compiled

successfully message once these steps are completed successfully.

If there are any other problems:

• Use the Dynamic C Help menu to get further assistance with Dynamic C.

• Check the Rabbit Technical Bulletin Board and forums at www.digi.com/support/forum/rabbit

and at www.digi.com/support/forum/.

• Use the Technical Support e-mail form at www.digi.com/support/.

NOTE: If you purchased your RCM5700/6700 Development Kit through a distributor or through a

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

• USB cable to program RCM5700/6700 via Interface Board.

Hardware Connections

Step 1 — Prepare the Interface Board

Insert a short plastic standoff supplied from the
Development Kit in one of the corner holes from
the bottom of the Interface Board, then secure it
with a long plastic standoff from above as shown
in Figure 1. Repeat this step so that plastic
standoffs/ connectors are in place at all four
positions.

Step 2 — Install Module on Interface

Figure 1. Insert Standoffs/Connectors

Board

Position the RCM5700/6700 module with the

edge connectors facing the mini PCI Express socket J1A at an angle as shown in Figure 2 below.

Insert the edge connectors into the mini PCI Express socket J1A, then press down on the opposite
edge of the RCM5700/6700 module to snap it into place in holder J1B.

Figure 3. Connect USB Cable

Your PC should recognize the new USB hardware, and the LEDs next to the USB connector on the
Interface Board will flash — if you get an error message, you will have to install USB drivers. Drivers
for Windows XP are available in the Dynamic C Drivers\Rabbit USB Programming
Cable\WinXP_2K folder — double-click DPInst.exe to install the USB drivers. Drivers for
other operating systems are available online at www.ftdichip.com/Drivers/VCP.htm.

Figure 2. Install the RCM5700/6700 Module on the Interface Board

CAUTION: Remove power before attempting to insert or remove the RCM5700/6700

in the mini PCI Express socket.

Should you need to remove the RCM5700/6700 module, use two fingers to hold back the spring clip
at J1B from the two RCM5700/6700 corners, lift up the edge of the RCM5700/6700 above J1B, then
pull the RCM5700/6700 away to remove the edge connectors from the mini PCI Express socket.

Step 3 — Connect USB Cable

The USB cable connects the RCM5700/6700 to the PC running Dynamic C to download programs
and to monitor the RCM5700/6700 module during debugging. It also supplies power to the
Interface Board and the RCM5700/6700 via the USB interface.

Connect the USB cable between USB connector J5 on the Interface Board and your PC as shown
in Figure 3. Note that the USB cable connectors are different at either end, so there is only one
way to connect them between the PC and the Interface Board.

The green power LED on the Interface Board should light up when you connect the USB cable. The
MiniCore and the Interface Board are now ready to be used.

NOTE: A RESET button is provided on the Interface Board above the Ethernet jack to allow a
hardware reset without disconnecting power.

NOTE: Pins 1–2 on header JP1 on the Interface Board must be jumpered to download and debug
applications and sample programs with Dynamic C running. Pins 1–2 should be left unjumpered
to run an program already loaded in flash memory.

CAUTION: Do not jumper pins 1–3 on header JP1 on the Interface Board.

NOTE: You must cycle the main power on/off after you install or replace a backup battery to

minimize current draw from the battery.

Run a Sample Program

Once the RCM5700/6700 is connected as described above, start Dynamic C by double-clicking on
the Dynamic C icon on your desktop or in your Start menu. Select Store Program in Flash on the
“Compiler” tab in the Dynamic C Options > Project Options menu. Then click on the “Commu-
nications” tab and verify that Use USB to Serial Converter is selected to support the USB cable.
Click OK.

You may have to select the COM port assigned to the USB cable on your PC. In Dynamic C,
select Options > Project Options, then select this COM port on the “Communications” tab,
then click OK.
