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…

sx1509 is already supported. Looks like it is done entirely in python, no mcu code is needed. From the documentation: “Due to the delay incurred by I2C communication you should NOT use SX1509 pins as stepper enable, step or dir pins or any other pin that requires fast bit-banging.” klipper/sx1509…
