I presume they've implemented the transmit with simple bit-banging a GPIO line.

I want to replace the secondary MCU with one of my own. I can implement the interface with just bit-banging, too, but if I don't have to - because it's a standard and someone has already written #code for the #RP2040 / Raspberry Pi Pico - then that would be great.

Anyone know if this is a standard I haven't found?
