Hello! I am learning how to build keyboards and I am trying to create a split keyboard that is split with a TRRS cable. I have got as far as wiring them on breadboards so that they can run simultaneously (just connecting VBUS to VBUS and GND to GND on both). I have looked for tutorials on using I²C to do so but they all seem to use Arduino-C. How can I use circuit python to connect these two to run together?
Edit: I will test on breadboards first, not on the real thing.
