Rotary encoder not working

Help and Support
1

Hello,

I’m trying to get my rotary encoder to work but failed so far. What I’m using:

  • I’m switching from HifiBerry to Volumio with an RPi 3B+ and a HifiBerry AMP2
  • With HifiBerry I have a working rotary encoder accoding to this article:audiocontrol2/rotary-controller-plugin.md at master · hifiberry/audiocontrol2 · GitHub
  • my configuration for the 5 pins is
    • clk = 23: GPIO23 = RPi PIN16
    • dt = 24: GPIO24 = RPi PIN18
    • sw = 25: GPIO25 = RPi PIN22
    • GPIO3v3 = RPi PIN 1
    • GPIO_GROUND = RPI PIN20
  • this configuration is working without any issues in HifiBerry
  • in Volumio I have installed the Rotary Encoder plugin in version 1.2.2 and configured the First Rotary Encoder according to the above mentioned pins CLK, DT and SW
  • problem is that I get no response on using the rotary encoder

What is wrong with that configuration? Any help is appreciated.

Which functions did you configure in the plugin (turn left/right, click)?

With journalctl I was able to access the log file while turning the knob:

But unfortunately I get no change in sound volume.

Ich versuche morgen mal einen Testaufbau mit einem frischen Volumio Image.
