    I am trying to implement a frequency counter in PIC16F887

    It should measure the frequency of the incoming signal like 0.0 , 0.1 ,0.2 ........................1.0,1.1,.2,..........................99.9

    Also I want to display this frequency on LCD

    If you have any idea please let me know

    Thanks

    I figured you may say that It is a little harsh. I have the code that Bill talked about.

    And some that I have done but it's in Swordfish Basic

    This is Wolfgang Buescher, DL4YHF It is easy to read and is freely available.
