struggling with ISR on digital pins
« on: August 07, 2019, 06:39:02 am »
Trying to get a bike computer working: two reed switches, one for pedal rotations, one for wheel rotations. Tried without ISRs - simple loop polling for digitalRead on pins 2 and 3 - works except it misses rotations when the wheel spins too fast.
