User’s Manual 9
To power down the Prototyping Board, unplug the power connector from J5. You should
disconnect power before making any circuit adjustments in the prototyping area, changing
any connections to the board, or removing the RabbitCore module from the board.
2.1.4 Alternate Power Supply Connections
Development kits sold outside North America before 2009 included a header connector
that could be connected to 3-pin header J5 on the Prototyping Board. The red and black
wires from the connector could then be connected to the positive and negative connections
on your power supply. The power supply should deliver 8 V–24 V DC at 8 W.
2.2 Run a Sample Program
Once the RCM2200 is connected as described in the preceding pages, start Dynamic C by
double-clicking on the Dynamic C icon on your desktop or in your
Start menu. Dynamic C
uses the serial port specified during installation.
If you are using a USB port to connect your computer to the RCM2200 module, choose
Options > Project Options and select “Use USB to Serial Converter” under the
Communications tab, then click OK.
Find the file
PONG.C, which is in the Dynamic C SAMPLES folder. To run the program,
open it with the
File menu (if it is not still open), then compile and run it by pressing F9 or
by selecting Run in the Run menu. The STDIO window will open and will display a small
square bouncing around in a box.
2.2.1 Troubleshooting
If Dynamic C cannot find the target system (error message "No Rabbit Processor
Detected."
):
• Check that the RCM2200 is powered correctly — the red power LED on the Prototyping
Board should be lit when the RCM2200 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 program-
ming port on the RCM2200 with the marked (colored) edge of the programming cable
towards pin 1 of the programming header.
• Ensure that the RCM2200 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 list, then click OK. Press
<Ctrl-Y> to force Dynamic C to recompile the BIOS. If 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.
