What is the easiest way to access FEZ Spider digital I/O ports? On Panda II you just look on the board, find new empty PIN and his number, create new OutputPort and write to it. No additional hardware required and so.
Can I do something similar also on Spider, without getting a few new Extenders? Can all pins on Extender be digital I/O (on which Gadgeteer port) and why there are only 7 pins and not 8?
Thank you for your help
