detect1 to 0 change on RA0

[med2007]

Why does this fall through?

loop:
IF porta.0 = 1 then loop

next lot of basic code follows here

RA0 is tied up via 10K and a press button grounds it, to get out of the loop, but...it fall thro anyway

Think analog...
Think datasheets...
Think about telling which PIC you're using...
Just a few things to think about...

And also your configurations, DEFINES, schematic, etc.

Why don't you post your code? If you seek help from experts, then do not worry about stealing you code... They sure know and do better!

With no infos, only guesses can be made. And I am not good at. If I was I would have won the Lotto or Casino or something anyway...

Thanks guys, the answer is to configure porta for digital I/O, which I hadn't done.
