JACDAC for STM32F0/STM32G0/...

You might have heard of JACDAC. It's a new protocol that aims to standardize connecting microcontrollers dynamically, and with very little wiring (one wire for data, one for GND, and optionally one for power). One scenario is networking of MCU-based devices, for example to enable multiplayer for your awesome MakeCode Arcade games. Another is connecting peripherals to a host device (joystick anyone?!).

• Preliminary notes on JACDAC v1

TODO

• implement reset counter and ACK flag in AD[0]
• consider thermal shutdown at 50C or so (assuming it's because of heat of some other component)
• use SI values for sensors with 16 bit scaling?
• add CTRL cmds for time and software version (different than hw!)
• the "combined" flashing doesn't work - figure out why
• UF2 flashing fails ("misaligned" error)
