1. INTRODUCTION
The RCM5600W and RCM6600W MiniCore modules provide a compact module in a mini
PCI Express form factor with integrated Wi-Fi/802.11b/g functionality to allow you to create
a low-cost, low-power, Wi-Fi based control and communications solution for your embedded system.
The RCM6600W allows use of Ethernet as well as Wi-Fi, which opens up many possibilities for embedded systems which require wireless as well as traditional, wired, connectivity.
A Development Kit is available with the essentials that you need to design your own
microprocessor-based system, and includes a complete Dynamic C software development
system. The Development Kit also contains an Interface Board with a USB connection that
will allow you to evaluate the RCM5600W/RCM6600W, and a Prototyping Board to help
you to develop your own applications. You will also be able to write and test software for
the RCM5600W/RCM6600W modules, including Wi-Fi applications.
The RCM5600W has a Rabbit 5000 microprocessor operating at up to 73.73 MHz, flash
memory, two clocks (main oscillator and real-time clock), and the circuitry necessary to
reset and manage the Rabbit 5000. An edge connector brings out the RCM5600W user
interface to a 52-pin mini PCI Express socket on the motherboard the module is mounted
on.
The RCM6600W is similar to the RCM5600W, except that it has a Rabbit 6000 microprocessor operating at up to 162.5 MHz. The Rabbit 6000 has 1MB of internal fast RAM, and
it is also possible to use Wi-Fi and Ethernet simultaneously. The RCM6600W also permits
four of the edge connector pins (PE0-3) to be selectively configured as analog inputs.
The RCM5600W/RCM6600W module receives its +3.3 V power from the motherboard
on which it is mounted. The module can interface with other CMOS-compatible digital
devices through the motherboard.
1.1 MiniCore Module Variants
This document describes four MiniCore module variants. The RCM5600W is based on the
Rabbit 5000 microprocessor, whereas the RCM6600W is based on the Rabbit 6000 and it
includes Ethernet as well as Wi-Fi. There are also two minor variants, the RCM5650W
and the RCM6650W. These variants add a larger serial flash memory (4MB instead of
1MB) but are otherwise almost identical to their -00W siblings.

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.
Once your installation is complete, you will have up to three new icons on your PC desktop. One icon is for Dynamic C, another 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 any of the optional Dynamic C modules, install them after installing
Dynamic C. The modules may be installed in any order. You must install the modules in
the same folder where Dynamic C was installed.

so, make sure that you use a long
plastic standoff instead of the antenna bracket. Then connect the wire
to connector P1 on the
RCM5600W/RCM6600W
, and attach the antenna to the RP-SMA
connector.
2.2.4 Step 4 — Connect USB Cable
The USB cable connects the RCM5600W/RCM6600W to the PC running Dynamic C to
download programs and to monitor the module during debugging. It also supplies power
to the Interface Board and the MiniCore via the USB interface.
Connect the USB cable between USB connector J5 on the Interface Board and your PC as
shown in Figure 4. Note that the USB cable connectors are dif
ferent at either end, so there
is only one way to connect them between the PC and the Interface Board.
14 MiniCore RCM5600W/RCM6600W
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.
The green power LED on the Interface Board should light up when you connect the USB
cable. The RCM5600W/RCM6600W and the Interface Board are now ready to be used.
NOTE: A RESET button is provided on the Interface Board to allow a hardware reset
without disconnecting power.
NOTE: Pins 1–2 on header JP1 on the Interface Board must be jumpe
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.
Alternate Power Supply Connections — Deluxe Development Kit
red to download
The deluxe Development Kit contains a separate AC adapter that may be used to supply
power to the Interface Board and the RCM5600W/RCM6600W when the USB cable is
not connected or when more power is needed than the USB cable is able to supply. The
AC adapter may also be used to supply power when the USB cable is connected, in which
case the power supply through the USB cable will be disconnected automatically.

2.3.1 Troubleshooting
It may be possible that your PC or laptop is unable to deliver enough current through the
USB connection if you are not using a separate power supply. The
RCM5600W/RCM6600W will not operate in this case, and the solution is to use a separate 5 V power supply as described in the Alternate Power Supply Connections section.
Contact Technical Support (see Section 2.4.1) or visit our Web sit e if you would like to get
the universal AC adapter from the Deluxe Development Kit.
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.
This same error occurs when Windows has already allocated the COM port to another
process.
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 that it is firmly plugged into the PC and the USB connector in the Interface Board. Ensure that the module is firmly and 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. Click OK
to save.
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 on the “Communications” tab in the Dynamic C
Options > Project Options menu. Choose a lower debug baud rate. Click OK to save.
Press <Ctrl-Y> to force Dynamic C to recompile the BIOS. You should receive a BIOS
successfully compiled
message once this step is completed successfully.

3. RUNNING SAMPLE PROGRAMS
To develop and debug programs for MiniCore modules (and for all other Rabbit hardware), you must install and use Dynamic C. This chapter provides a tour of its major features with respect to the RCM5600W/RCM6600W.
3.1 Introduction
To help familiarize you with the Wi-Fi enabled MiniCore modules, Dynamic C includes
several sample programs. Loading, executing and studying these programs will give you a
solid hands-on overview of the MiniCore’s capabilities, as well as a quick start with
Dynamic C as an application development tool.
NOTE: The sample programs assume that you have at least an elementary grasp of ANSI
C. If you do not, see the introductory pages of the Dynamic C User’s Manual for a sug
gested reading list.
In order to run the sample programs discussed in this chapter and elsewhere in this manual,
1. Your MiniCore must be installed on the Interface Board as described in Chapter 2,
“Getting Started.”
-
2. Dynamic C must be installed and running on your PC.
3. The USB cable must connect the Interface Board to your PC.
4. Power must be applied to the MiniCore through the Interface Board.
Refer to Chapter 2, “Getting Started,” if you need further information on these steps.
To run a sample program, open it with the File menu (if it is not still open), then compile
and run it by selecting Run in the Run menu (or press F9). The MiniCore must be in Program Mode (see Figure 14) and must be connected to a PC using the USB cable.
Complete information on Dynamic C is provided in the Dynamic C User’s Manual.
