It's been a while since I worked on this project, but I am preparing to put the boards and keyboards up on Tindie so I can sell them.

In preparation, I had to clean up the mess that is the documentation and add some examples.

You can go here to see the documentation for the I2C protocol, feel free to submit PRs if something is missing or unclear.

I also wrote libraries for CircuitPython and Arduino so people who buy the PMOD have a starting point for their code, you can find them here and here.

I will publish another update when the Tindie listing is up.
