Boy do I feel stupid... I must have got my 16F877
and 16F84 mixed up.. Does anybody know of a way
of measuring analog signal w/16F84?  I know I've
seen something about using some cap's & resistors
and measuring the time it takes to charge the caps,
but I can't seem to find that page again... Does
anyone have more information on this method, or
any method for that matter that might work?
