So, if you have a recent version of All-In_Circuit, you can follow these simple steps for adding your custom switches:

 

So, if you have a recent version of All-In_Circuit, the only things you have to do is:

* Update your zynthian

* Update your zynthian

** Select MCP23017_EXTRA as wiring layout. This will set your ZYNTHIAN_WIRING_SWITCHES to “100,103,108,111,106,107,114,115”
