I have a little job going through ( big in terms of cash, but the small in
terms of size). At it's heart is a pic 16f877 with a 32.768khz xtal which
won't go.
After initial hassle, and a phone call to the manufacturers, I now have
2x22pf caps from each end of the xtal to ground, (for ~12.5pF load) and a
resistor in series with osc2 of 1.1k (CMAC suggested not less than 300 ohms
and not more than 2K). Nothing. nada. I have tried lower & higher resistance
and capacitance. I did swap pic and crystal for new parts at the same time.
Any ideas?
