There's no Pull-up on PORTA. Must use external one wich is always the best pratice... well IMHO.Originally Posted by vicce
AND PIC16F676 have internal comparator on PORTA, as i thought, so you must add
CMCON=7
to the top of your code
CMCON=7, click,CMCON=7, click,CMC, click,CMCON, click,CMCON=7, click...
AND, the last one, ADCON1, is not the one you need to set A/D channel. You need to set ANSEL

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Although I agree an external pull-up is better....
TFM states...."Each of the PORTA pins, except RA3, has an individually configurable weak internal pull-up."
