Hmm, I think there is a general misunderstanding in this forum.
We cannot help if we don't see any code that you have tried. There are many examples in this thread (try from the page 1 and after) for various PIC.
But we really need your code that is not working and your circuit.
By speculating I think solution cannot be found.
Here's a link for an older post
