Re: [PIC] CCP1 Glitches in noisy environment (RC Tx)

I got rid of the RF noise by removing the crystal and to my surprise I'm
still getting glitches.  There is now a non-measurable amount of noise as
far as I can detect.

The glitch happens when the ISR returns to the main program.  The number of
instruction cycles matches the time delay to the glitch exactly.  I even put
in a time delay in the ISR to confirm that.  This point is a long way away
from any pin being turned on or off.

Anyone heard of anything like this on a 16f886 or similar device?

Regards,

Gordon Williams
