There's so much good embedded OS work happening. These Bluetooth, wifi, matter problems? Pretty well tackled by Zephyr & others. It'll be interesting to see if "rewrite it in Rust" really can re-do all these efforts satisfactorily. Or to see how Rust & C interop goes (as Linux is doing). Or whether Rust remains useful & awesome on embedded if and only if you don't need complex protocols and device drivers.

> Pretty well tackled by Zephyr & others Yeah, we started using Zephyr about a year ago at work and while it hasn't been seamless it has been pretty darned awesome. One of the more interesting outcomes is that, more often than not, we've shifted from "lots of stupid easy bugs" to a smaller handful of "tricky to debug" bugs, around half of them being actual hardware issues and not strictly code issues. One of the most amazing things has been being able to take the same firmware code and run it on our v1 production board using a Cortex M0 and on our v2 prototype board using a Teensy v4.1 Cortex M7 board and all we really needed to do was modify the devicetree to remap which peripherals and pins were connected to the rest of the hardware. Amazing! One of my coworkers has started using Rust on a personal embedded project (on an STM32 processor of some kind). Once we're done this current prototype cycle I want to sit down with him and see what he's got figured out. Seems like a cool place for Rust and all of the memory safety goodness.
