Make a short (the shortest possible) test prog and get the
pins working. Then change your application accordingly.

There is a lot in the posted code that has nothing to
do with setting the pins. Noone wants to read that.
Remove interrupt, timers and so on.

This is simple fault tracing. Simplify until the
problem is clear.

Jan-Erik.
