On the one side I really like c and c++ because they’re fun and have great performance; they don’t feel like your fighting the language and let me feel sort of creative in the way I do things(compared with something like Rust or Swift).

On the other hand, when weighing one’s feelings against the common good, I guess it’s not really a contest. Plus I suspect a lot of my annoyance with languages like rust stems from not being as familiar with the paradigm. What do you all think?

    A lot of those mcus don’t need to run particularly complex programs. Many of them don’t do anything more complicated than reading the status of a pin and using that to activate another pin. 75MHz with a Rust program is more than enough.

    For that matter, when Python was first released, the Intel Pentium wasn’t even out yet. People made it work. Micropython could handle the above just fine provided the polling rate didn’t need to be that high.

    It’ll all depend on the application, of course, but a huge number of mcu programs could easily be Rust. The performance hit is not that big. The code size on lower end mcus is also going to be naturally limited by their flash space, so even the compiler speed isn’t going to be a big hit.

    One thing is that the last time I tried using Rust on an esp32, the toolchain was still in its infancy and didn’t work very well. Looks like Go has been ported in, as well, but it doesn’t support wifi or bluetooth on the esp32. Or even i2c or pwm.

      I haven’t seen a test on the difference between rust and c, but your last point is the biggest caveat for rust is your last point.

      If you have been running the same toolchain on multiple products, changing the language means a productivity loss because the devs need to learn the ins and outs of the new language, and if the toolchain is buggy, then it is another productivity loss.

      I’m always eager to try out new stuff in products I design, but the incertitude and productivity loss is a no go because I can just spin a barebone code that works in half a day.

      Until the tool chain is mature, C will still exist.
