i happen to have a prooblem with my code. it seems like its very difficult to debug than to start a new program.
Can anyone help me find a problem with the code. i am not sure whether you will be able to understand the code if you can't please let me know. if you need it's intended operation just let me know.

If you wrote in PIC assembler it might help?.

What is that?, is it the long defunkt Parallax assembler?.

Wow, what is that?

Is it PIC51 mixup ? :lol: :lol: :lol:

As I suggested above, it might be the old (REALLY old!) Parallax PIC assembler - and we've got members on this board younger than that!. It's not been used since well into last century, and there's certainly no reason at all to be using it now!.

As far as I recall it was discontinued well before the 16F84 ever saw the light of day?.

Apparently it was intended to make PIC programming easier for 51 programmers, essentially it's just a series of macros.

That would explain why it uses pic16c84.

And I was right, it is PIC51 mixup (51 style code on a PIC).

Another suggestion:

I would love to take a shot at fixing your code. However, you should make it easy for us to help by posting it in "code" format.
