Options For Changing Switch Positions

In a post discussing possible DIY expander modules, Dan provided some information on how the expander modules will communicate with the MetaModule:

The button and pot expanders use I2C plus jumpers for address select. The audio expander uses I2C plus I2S. There’s no protocol for the MM to query an expander’s capabilities and then reconfigure the audio engine to accommodate X number of pots, Y number of buttons, Z number of LEDs, etc… Instead, each type of expander is an entity with pre-defined numbers of each.
