Hello,
I installed the rotary encoder plugin v1.2.2 within Volumio and entered the required gpio pins.
While turning the knob, the volume control I selected in the setting works perfectly using 67nf capacitors, but I can’t get the push-button functionality to work. I tried many different gpio-pins (except gpios 3,5,18,19,20,21 which are used by the hifiberry amp2), but no success. I measured the encoder (KY040), pushing the button connects the sw-pin to the ground-pin, so to me the encoder seems to work properly.
Any help would be very appreciated, thanks in advance,
Phil
edit: updated to volumio 2.799, same problem.
