Haven't dug much into this yet, because a) not sure how to, and b) not sure if it's actually a bug or a legitimate limitation (for some obscure technical reason).
Say I have an I2C module plugged in on port A. In theory this should only need pins 1 & 2.
The question is, does calling tessel.port.A.I2C(...) disable all those other spare pins (2..7)? I'd love to be able to still use those as GPIOs, but my initial attempts have led to some bizarre results.
Bug or limitation? Or perhaps I did something else really dumb.
