Hi @LFO !
I’ve been checking and you should not specify the zynpatik pins. They will be auto-asigned from 200 to 215. Trying to configure these pins will cause trouble,
In other words, you must configure the switch pins only for the first MCP23017, where encoders and switches are connected together, so you need to specify what pins are used for encoders and for switches. The second MCP223017 is configured as zynaptik and pins are auto-asigned.
