I used SigmaStudio to program the DSP, which works really well - great project!
Now I tried to connect a rotary encoder for volume control to DSP MP6/7, but can't figure out the settings for the MPs to make it work (with SigmaStudio's "Volume Rotary" block).
I configured both MPs as "Input from Pin" in the DSP's register controls, but all I manage is to make the MP7 LED blink... the MP7 LED beneath the RPI makes me wonder whether MP7 is actually used for something else.
Can any of the other MPs be used? Any advice on the configuration? Thanks!
