I think he meant that relying on accuracy exceeding the Microchip specs is bad, not using the internal oscillator if the published accuracy is acceptable. The internal oscillator can be a very cost effective way to clock a PIC (I've done this a bunch of times) - as long as you aren't counting on more accuracy than what Microchip promises. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
