Hey,
If you read my previous blogs on using GPIO pins, you'll remember that we had to export the number "81" in order to activate pin C17. I thought it would be nice to have a lookup table to what number corresponds to what pin.
I've attached a pdf of the numbers to pin assignments with some comments.
My XGPIO python library is going to contain a lookup list so you can use the pins as they are printed on the board e.g. C17 and not have to use the numbers (81).
