I have used toit in a lot of my projects. It is a really nice language and so much cleaner than all the alternatives I have tried (Arduino, Python, Lua).

The tools just work and I got used to the language really quickly.

I did hate that it was bytecode. It just felt wrong to run bytecode on an ESP32. OTOH it just works, and I have never noticed any performance problems.

My latest project is a controller for a slave-clock: https://gitlab.com/close2/nebenuhr-toit (There is also a Garmin repository that allows me to control the clock using my Garmin watch.)

Full disclosure: I had to use toit (floitsch is my brother), but it really is a nice language and development environment.
