    Default High End Pre with PIC 16F876A

    Hi Guys:
    I am quite new to PIC Programming and I thought it would be an excellent place to learn about it at this forum.
    I have been working on this idea of developing a high end pre around PIC 16F876A, though as far as I could go the porject works fine as long as I use up, down and mute buttons.
    But I cannot figure out a way how to configure that input selection stage so that one button changes the input (a total of four inputs) and when it reaches input 4, any new press on button input shifts the input to "input 1". I use ULN2803 for driving relays.
    Appreciate if guys here could help me out.
