Nick, I did not parse your code, but here is a suggestion for
the next time you're beating your head against the wall over
something like this. Simplify it to 1 step at a time. Do the
timer stuff, and get it working correctly via polling the IF
flag without doing the interrupts. Once that is good, then add
in the interrupt stuff.
