I am using Micropro and a K programmer. Antipodean Super Member Total Posts: Makram New Member Total Posts: I’m using a 4mhz 3 pin ceramic resonator with 22pf capacitors connected to it.

This does not directly effect your code since you are only using portB which is only digital but if you use portA for digital then you will need to disable the analog features.

I removed the external capacitors however the problem isn’t solved. COO Country of Origin: To be sure check the resonator’s data sheet. The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering. Why pic16f8874 my PIC32 run slower than expected? Haven’t received registration validation E-mail?

The three term resonators typically have the caps built in so no external caps are needed. Schematic looks ok if you have the Vdd and Vss pins connected with a 0. You say you are using a three terminal resonator with external capacitors – should it have external capacitors?

This powerful nanosecond instruction execution yet easy-to-program I’m starting to wonder if the MCU is damaged although I’m using 4. If you have already tried 2 PIC16F chips then it is unlikely to be the PIC – they are remarkably robust and unless both are pulls from the same previous catastrophically failed project, they would be unlikely to be blown the same way and still program and verify.
