Can anyone suggest some solutions?
RS Components Statement of conformity. This powerful nanosecond instruction execution yet easy-to-program Makram New Member Total Posts: Forum Themes Elegant Mobile. I’m using a 4mhz 3 pin ceramic resonator with 22pf capacitors connected to it.
How are you programming the code into the PIC? Here is a good tutorial that will help: Do not use my alias in your message body when replying, your message will disappear I tested the source code using proteus and it worked fine.
I am using Micropro and a K programmer. I have the decoupling capacitors between each vdd and vss pi16f874. 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. Standard Pack Production Pack. Why does my PIC32 run slower than expected?
PIC 16F874 not working
Schematic looks ok if you have the Vdd and Vss pins connected with a 0. You should try setting them in your code which may work better. pjc16f874
That should get your PIC running at approx 3. Check that with a scope or frequency meter. If you have already tried 2 PIC16F chips then it is unlikely to be the PIC – they are remarkably robust and unless both are ;ic16f874 from the same previous catastrophically failed project, they would be unlikely to be blown the same way and still program and verify.

Try a RC oscillator. To be sure check the resonator’s data sheet. 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. Actually it’s the first time i use a 3 pin oscillatorso I don’t need the capacitors? Good catch from Alan. Now supplanted by Flash based variants these User Control Panel Log out.
COO Country of Origin: Originally launched as One Time Programmable OTP parts, this range of devices continues to expand as extra features and further improvements are added. Microcontroller Features 20 MHz Max. In addition, some of the ports default to analog inputs. Didcot, United Kingdom Status: 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 The restricted substances and maximum allowed concentrations in the homogenous material are, by weight: Antipodean Super Member Total Posts: M Super Member Total Posts: Forums Posts Latest Posts.
If you can get a PIC16F Ait uses a slightly different programming algorithm and may work better with your programmer. The three term resonators typically have the caps built in pic166f874 no external caps are needed.

Haven’t received registration validation E-mail? You say you are using a three terminal resonator with external capacitors – should it have external capacitors? I removed the external capacitors however the problem isn’t solved.
