2.3 Starting Dynamic C
If you already have Dynamic C installed, you are now ready to test your programming connec-
tions by running a sample program. 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 “Communications” 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
.
2.4 Run a Sample Program
Find the file
PONG.C
, which is in the Dynamic C
SAMPLES
folder. 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.
This program shows that the CPU is working.
2.4.1 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. 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 con-
nected 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 lower-
ing 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 compiled
successfully
message once this step is completed successfully.
