Anyone seen such a thing before.... on the face of it, my ADC seems to be reading fine...if I put a pot between VCC & Gnd, I see the wiper reading increment as expected up to 255 ....but then when I turn it down fully, I don't see readings below 008...even if I short the ADC pin to the PIC's ground connection (ie to eliminate the pot as being the source of the problem).

i've tried other ADC pins....the same.

I'm at a loss as to what might be going on here?
