Does this work with the Raspberry Pi Zero to give it Ethernet? From my testing, yes, but I needed to use the USB-data port rather than USB-power. As far as […]

Rotary encoder working on Pi 3 but not on Pi 4

I’m trying to read an encoder switch using wiringPi (latest, 2.52). Whenever there is an edge on either of the encoding pins a or b, I store a snapshot of the state of both pins on two bits: int val = 2*digitalRead(pina) + digitalRead(pinb) A separate process then filters out repeating states and then looks […]
