Firmware anode #23

Closed rkjdid closed 6 years ago

rkjdid commented 6 years ago

a good amount of rework to the firmware to use the idle time of the arduino to compute voltage.

this allows quasi-instant answers from the arduino, the average is constantly recalculated using some voodoo values (chunk sizes of 50, delay(5) in main loop)

there is also a cool auto-calibrate of AREF feature in there, taken from arduino's forum board.

feedback & testing welcome!

youpi from 250ms to 7ms ReadVoltage()
