Stellaris Launchpad: GPIO Mapping

Unlike the previous TI Launchpad, now referred to as MSP430 Launchpad, the Stellaris does not bring out all available IO to the user. It's based on a LM4F120H5QR, a 64-pin device, and the Launchpad brings out 40 pins.

I've mapped out the available IO below:



As you can see, there's only one port that has a full 8-bits available. So, plan your I/O well and look forward to a lot bit manipulation between the ports.
