delay_cycles crashes my code!
PostPosted: Fri Jan 27, 2006 4:22 pm     Reply with quote
I am working on a PIC18F2410 and the following odd action happens in my code. The code will reset the processor on the delay_cycles function. I have tried moving the code, walking through with the ICD-U40, and changing the surrounding code.

Code:
void CodeCrasher()
{
  LED_OFF;
  LED_ON;

  output_high(PIN_B1);
  delay_cycles ( 20);
  output_low(PIN_B1);

  LED_OFF;
}


When I step through the code I get the following error:
"Invalid Clock Value from the debugger. Debugging may not have been enabled."

Any help would be greatly appreciated.

Is this entirely a debugger issue ? Does it still crash when the code
is programmed into the PIC so that the program runs in Stand-alone
mode ?

Error may not be code

The crash happens all of the time. However the EE now says that it may be a trace problem with the board. We are going to try a different board. Wish he would have told me that before I posted for help. Thank you for all of the effort. I appreciate it.

1) LED_OFF; // is th¡s to be sure that it should be OFF ?
LED_ON;

2) Do you have INT_EXT1 enabled for any reason ?
If so, did you coded the handler ?
