"Apparently all timer/capture/counter resources and interrupts are used. So I used PK0/AIN8/PCINT16 and PK1/AIN9/PCINT17 as PCINTs. Used a shaft encoder index pulse for the upcounter, and optocoupled tachometer output pulse from the ignition system."
I'd like to add two timer/counter related features to ArduPlane 2.28:1. Simple 32-bit event up-counter, capable of counting input pulses at up to 1kHz, and logging the count. (Counter clears at power on, for now).2. Shaft RPM counter, capable of…
