Re: Wiring it up for VEX.
My team built some off season robots using the VEX microcontroller platform. Personally, I found it to be very ungainly. There are several key limitations to this system, the largest being that you cannot (in any way that I know of) connect it to a computer and control it using a conventional dashboard program.
If you are interested in replacing the cRIO and digital sidecar with a different microcontroller and I/O board, I would recommend using an Arduino. They are very easy to program, and the native Arduino language interfaces well with the computer based Processing language.
What this translates into for you is a cheap (only $24 for the Arduino) and robust (fully compatible with all of the FIRST approved speed controllers, etc) microcontroller that will accept inputs from your Xbox controller.
