Microcontroller Features 20 MHz Max. Didcot, United Kingdom Status: I wouldn’t trust the K programmer even if it is a genuine Kits ‘r Us one. Pic16f74 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 pic16t874 and verify.

Can anyone suggest some solutions? How are you programming the code into the PIC? Haven’t received registration validation E-mail? 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.

If you can get a PIC16F Ait uses a slightly different programming algorithm and may work better with your programmer. I am using Micropro and a K programmer.

Here is a good tutorial that will help: Essentials Only Full Version. 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: In addition, some of the ports default to analog inputs.

picc16f874 Try a RC oscillator. Why does my PIC32 run slower than expected? Pic116f874 three term resonators typically have the caps built in so no external caps are needed. Problems with Programming Oscillator in XC16 Is it possible to stretch a pulse signal using only microcontroller? Check that with a scope or frequency meter. Schematic looks ok if you have the Vdd and Vss pins connected with a 0. Actually it’s the first time i use a 3 pin oscillatorso I don’t need the capacitors?

To be sure check the resonator’s data sheet. Good catch from Alan.

I tested the source code using proteus and it worked fine. If it’s recommended to set them by codecan you give me the write code for that.
