Post by thread:[PIC]: Chip test program??

Is there any program written to exercise a PIC to see if it is working properly? I know it couldnt be perfect, but I searched the net looking for code that might have been used to verify probably good operation of a pic. I'm interested in overclocking, and I'm sure others are too, so I figured someone might have written a routine that pretty well wrings out a pic to verify correct operation. I tested some 4 mhz chips with a little sequential led flashing program, and these chips "seemed" to work at 20 Mhz, but still, I feel uneasy about overclocking anything unless I have a pretty good feel for it.

In the uChip Advanced seminars (IIRC) they discuss this; Anyone know if that concept's on the uChip web site? Don't want to do this on an OTP part unless you make it part of your power-up code, of course. Mark Don B.
