If I'm going to have to shell out a bit more for the microcontroller to get an "E" grade PIC (for example) I'd rather not keep adding cost for an external oscillator. But this thread is generating some good ideas. :-) Rob Young rwyoung@ieee.org -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
