Hi there! New to this forum, so I hope I’m doing this right! I’m wondering if I2C or SPI I/O expanders could ever be supported in Klipper (MCP23017, MCP3008, etc.) Thinking of this because I think it’d be neat to design an RP2040-based mainboard with a few I/O expanders on it. That could be a really cheap and easy solution in terms of mainboards.
Has this been discussed before? I searched around and couldn’t find anything. I have decent Python skills and preliminary C skills if a PR for this would be welcome, but I might need someone to point me in the right direction. I also have the hardware on hand to do some tests. Thanks!
