2.3 Run a Sample Program

If you already have Dynamic C installed, you are now ready to test your programming
connections by running a sample program.
If you are using a USB port to connect your computer to the RCM3000 module, choose
Options > Project Options
Communications tab.
Find the file
PONG.C
open it with the File menu (if it is not still open), compile it using the
then run it by selecting
play a small square bouncing around in a box.
This program shows that the CPU is working. The sample program described in
Section 6.10, "Run the PINGME.C Sample Program," tests the TCP/IP portion of the board.

2.3.1 Troubleshooting

If Dynamic C appears to compile the BIOS successfully, but you then receive a communi-
cation 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 Options > 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 Options > Project Options >
Communications menu. Choose a lower debug baud rate.
If there are any other problems:
• Check to make sure you are using the PROG connector, not the DIAG connector, on
the programming cable.
• Check both ends of the programming cable to ensure that they are firmly plugged into
the PC and the programming port on the RCM3000.
• Ensure that the RCM3000 module is firmly and correctly installed in its connectors on
the Prototyping Board.
• 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 active COM port.
