I just recently bought the PICkit 2 board and have been having a lot of fun messing around with the programs and learning assembler. But i have ran into a problem that seems should be really simple to me, and my intended project can't continue until the problem is solved. The issue is this: how do i connect a switch to input? I'm looking for a way that i can initiate a sequence of delays and output pins with the press of a button. I've set the ports to input, used all kinds of loops, messed around with the ANSEL thing and i still can't get anything to work! Please help me out here! Also i'm still very new to this so if there is any good material you would recommend i read that would be great. Thanks!

Get the student 18 C compiler (free).
And this includes some example code.
1. Make sure flags default to digital i/o on start up
2. Initialize port direction configuration
3. Pull the input to vcc with a 10k resister (or portb pull ups enabled)
4. Switch ties input to ground
5. Read...
C::
if(myPortMacroAlias.pin0 == 1)
ASM::
Read port, AND mask, and branch if not zero.
The Microchip forum is very helpful regarding chip specific assembly issues.
Cheers,
