Dale, I am running an external 20Mhz ceramic resonator. The timing appears to be correct. The part runs, I just get no ADC value. Vref is VDD and the input to AN0 can be adjusted from 60mv to 4.2V. The ADC returns [0]. Using MPLAB v. 6.10.00 the simulator indicates that the ADC should be working. The step through looks good... ?????? More confused, to much information, overload inevitable...... Caution Will Robinson........Danger, Danger......
