      I am building a custom board with a MCP23008 and some other gadgets. I need a way to access the i2c bus and address this chip. Since the UniPi already has one on board, there should be no problems. From what I figure out, I just make a new instance of the class UnipiMcp with the correct address. After digging into the sources, I figured out how to add a config block.

      [MCP_2]
      i2cbus = 1 ; link to I2CBUS_X
      address = 0x21 ; i2c address

      Look suspiciously similar to a EMO-R8 doesn't it?

      So I can treat my odd card just like the EMO-R8 even if it does something completely different?

        @tradlost.se Basically yes, but since I do not know much about your board it is hard to tell.
