Your main problem will be the logic levels - Spartan3 is a 3.3V device
and is not 5V tolerant. And there are no level-shifters on the Starter

A cheap option for 3.3V<->5.0V conversion when you are playing with

I'd recommend getting a couple, one for inputs, one for outputs.

I would have thought I'd need bidirectional capability somewhere in there, no?
