The way _I_ do debugging on non-ICD2-capable PICs is to connect a piezo=20
beeper to an unused pin, and beep out in MORSE CODE the value of the ADC=20
while running.

I track a firmware loop it by first clearing a memory location, then set=20
bits in it as the PIC cranks through thr code.

Morse code is very easy to learn, especially just the 126 hex values.

I'll send some actually-used code if you like. Uses about 50 pgm words=20
in the PIC12 and PIC16 devices.
