I am in need of some help with the GPIO pins on our board. I just got my coldfire demo kit hooked up to my PC so I can compile and debug. I have read the documentation and I still cannot grasp how to work with the pins in codewarrior. How do i initialize and send outputs to the pins? I am trying to connect this LCD to my MCU,

I have gone through this tutorial but still cannot understand how to change to real gpio pins.

I really cant find anything online that can help me directly.
How can I create some easy code to output something simple?
If you can steer me any way in the right direction on figuring out how this works I would be greatful.
Thanks,
Ray
This forum is about both ColdFire and Power Architecture parts, so you are in the right place. Be sure to look at some of the example programs in the (CodeWarrior_Examples) folder that is within the CodeWarrior installation folder. There should be one that demonstrates basic I/O in there.
