Yes, unfortunately the internal oscillator is not stable enough to do USB -= even though they do have other chips with an internal oscillator that is g= ood enough, but I think they are all PIC24 chips. One would have thought they would have tried very hard to get that technolo= gy into this chip, as it does seem to be such an essential cost saving for = this chip and its smaller brother, the 18F13K50. --=20 Scanned by iCritical. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
