Even for small 4/8 bit soc systems?
I had the idea that C was the go-to language for that.
There's Assembly for those
Yes: https://github.com/avr-rust
When you're writing code involving global state and interrupts, and any access to an integer larger than a u8 needs to be surrounded by cli() and sei() just for guaranteed atomicity, then you will truly come to value rust's statically enforced thread / memory safety.
Are those still in use? With how cheap modern MCUs got, it kinda seems like it often makes more sense to get smth a bit more powerful and get the benefits of overall easier and faster development. May be wrong here, tho -- it's not like I compared numbers or something
Addit: I mean, 8 bit may easily still be a bit cheaper, yet corps will likely spend more than the difference in price paying devs
It probably won't do anything less than 32bit, so that's at least one thing C is good for.
