BUT, A lot of times, I'm not doing anything clock-sensitive, 8Mhz is way more than enough, and dealing with the XTAL and the couple of caps (or not, if you (unfortunately) have a high-pf breadboard) can be fun. In all fairness to the PIC devices, however, I will state that the XTAL driver on a PIC is remarkably robust. I suspect most of my dislike of XTALS when prototyping comes from some of the earlier micro's that I've dealt with which were a lot more sensitive, and the fact that I seem to be able to knock an XTAL's pins out of the breadboard by just breathing nearby. -forrest -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
