2.5 Starting Dynamic C
Once the OP7200 is connected to your PC and to a power source, start Dynamic C by dou-
ble-clicking on the Dynamic C icon or by double-clicking on the
.exe
file associated with
DcRab
in the Dynamic C directory.
Dynamic C assumes, by default, that you are using serial port COM1 on your PC. If you
are using COM1, then Dynamic C should detect the OP7200 and go through a sequence of
steps to cold-boot the OP7200 and to compile the BIOS. If the error message “Rabbit Pro-
cessor Not Detected” appears, you have probably connected to a different PC serial port
such as COM2, COM3, or COM4. You can change the serial port used by Dynamic C with
the
OPTIONS
menu, then try to get Dynamic C to recognize the OP7200 by selecting
Reset Target/Compile BIOS
on the
Compile
menu or by pressing
<Ctrl-Y>
. Try the dif-
ferent COM ports in the
OPTIONS
menu until you find the one you are connected to. If
you still can’t get Dynamic C to recognize the target on any port, then the hookup may be
wrong or the COM port might not working on your PC.
If you receive the “BIOS successfully compiled …” message after pressing <Ctrl-Y> or
starting Dynamic C, and this message is followed by a communications error message, it
is possible that your PC cannot handle the 115,200 bps baud rate. Try changing the baud
rate to 57,600 bps as follows.
•
Locate the
Serial Options
dialog in the Dynamic C
Options > Communications
menu. Change the baud rate to 57,600 bps.
