/**
|
|
* boardPinToNumber — the bridge between a board element's PAD NAMES and the
|
|
* GPIO numbers the simulators speak.
|
|
*
|
|
* A board whose kind has no branch here falls through to `return null`, and a
|
|
* null pin means every wire to that header silently connects to nothing: the
|
|
* part sits on the canvas, the sketch reads a dead pin, and nothing reports an
|
|
* error. That is what happened to the M5 Cardputer, whose EXT header and Grove
|
|
* Port A were unreachable even though the element drew them.
