Encoders made EASY?

[gilrain]

You have to use the WiringPi numbers (wPi on your picture):
A-pins: 10,21,23,28
B-pins: 11,22,24,29
Switches: 14,26,27,25

Ecoders directly to the GPIO of the Pi 4?

Thanks for the pictures and detailed connection details. I can see the issues… First you must use the WiringPi numbering scheme, not the BCM scheme so use these numbers: [image] Next you need to avoid the serial port on physical header pins 8 & 10 (GPIO 15 & 16) as these are used by Zynthain for its physical MIDI interface. Even if you don’t wire it out the Zynthian still enables the MIDI port and uses these pins. I have tested each of the following GPIO and proven they all work so you shou…
