I tried to figure out how to program the 'f628, but wasn't able to get it to work. It would just draw a lot of current when the programming voltage was raised high. If you figure anything out, I'd love to hear about it. Otherwise I am looking toward a different PIC. (16f877 I believe will work for my application) Thanks again -Steve -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
