Nevermind I retyped all of the programs and for some reason they all work fine now. :shocked: Must be a noob mistake or something. I am now trying to figure out how to turn pins into input; basically just connect them the ground. My programs aren't turning the appropriate pins to gnd so i am all confused. Attached is one of my first programs where I am trying to find out how to connect the pins to ground. My assembly language "vocabulary" isn't quite expanded so any help is appreciated. ;-)

Calebjo,
Turning a pin to input and connecting a pin to ground are not the same thing.  When a pin is an output, you can set it high or low.  When high, it sources the power supply voltage, when low it is connected to ground.  If you turn a pin into an input, it goes into Hi-Z mode which means it is floating and not connected to anything.

Thanks,
PeterM

PeterM,
Thank you for clarifying that for me. How would you instruct the SX to set that output pin to high or low? What would the progam code be for that?
Thanks for your consideration,
Calebjo

Calebjo,
Here is a sample program that sets various pins of Port A as outputs and lets you set them high or low.

Thanks,
PeterM

PeterM,
    Thanks for the sample program and clearing the high and low up for me! Now i can actually connect things to ground instead of turning them to Hi-z state. Thanks again!
