Rotary encoder on Merus Infineon audio amp HAT
#4
Thank you the quick replies!

I am using the standard rotary encoder driver included with moOde. Also, I am using all of the default encoder settings. The only changes made were to enable the rotary encoder and to choose either software, fixed, or null volume control.

The resistors and caps on the test circuit are as spec'd by Bourns, 10K Ohm and 0.01 uF.

Sorry, I should've been a bit clearer. I power up the Pi setup in the configuration shown in the attached photos. Music will play. I turn the encoder knob, either direction, only one click, the the music will stop playing.

The lights on the Pi do not go off. The status light occasionally blinks, indicating that it is still alive. The UI does, however, does not respond.

I have tested the circuit without the Pi. The outputs for the encoder channels show about 2.8 volts. When the encoder is turned, the voltage briefly drops to zero, then returns to 2.8 volts.

I'm miffed. Seems like the circuit is okay, but I'm admittedly a newbie to encoders.

Again, much thanks!
