> your original message mentioned PGC and PGD being > connected, but nothing is said about /MCLR and PGM. Sorry, let me clarify. Vpp/MCLR is tied to Vdd with a 100k resistor and a diode in series to block the 12v from getting at the 5v (so to speak). There is no PGM pin on my programmer, so I just hooked it to GND/Vss. It seems like it's writing fine, but gets an error when verifying (reading) I think. Initially I suspected it was noise or something messing up the PGD&PGC lines, that's why I wondered about maybe pulling them two to Vdd. The part was brand new when I installed it if that matters. Thanks for any other suggestions anyone has. ===== MJ Brush LeftClick.ca Internet Media Services mbrush@[NOSPAM]leftclick.ca ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
