Timer using PIC16F877

[Alin]

Hi .... I need some help if someone can help me ... I made a timer using a PIC 16F877 ... electrical diagram is made by me, is attached, and must fulfill several functions, so I have 5 buttons ... START / STOP, etc different functions.
But I need a little help in programming the PIC that I'm not good .... can someone help me to realize the code? thank you very much

There is a wealth of code and examples here on ETO..In the articles you will find a lot of code written for the mid range pic....
