Not all pins can can work for all functions .
Check features like pull - ups , pwm , etc before
re - assigning numbers
( gpio34 - 39 ) are inputs only and don ' t have software pullup / down functions
You MUST use external pull - ups or noise WILL cause problems .
Unlike the AVR version certain pins are not forced into the same port .
Therefore , bit masks are not use the same way and typically should not be
changed . They are just preserved right now to make it easy to stay in sync
