Wow I'm impressed at the developer experience. A reset button, flash with `make install`, woa. I've programmed plenty pro embedded systems that had substantially worse support. Hacky flasher apps, messing around with the power source, definitely no USB connector (on such a small board even). Super cool!

There’s even an emulator that is super helpful when designing new complications https://www.sensorwatch.net/docs/firmware/simulate/focus/

The firmware code quality is good as well. Well documented and easy to extend. It’s clearly a labor of love.

At this point tbf I think this protocol (UF2) that MS collaborated on is the easiest I've seen: https://makecode.com/blog/one-chip-to-flash-them-all.

Just drag and drop, or detect the specific mass storage, or save to location from browser. Super easy.

Which, after checking that Casio mod site...is exactly what they use! So never mind ha ha. But the blog post on UF2 is certainly worth a read; it's just so simple, it's brilliant.
