Show HN: Rust, ARM Cortex M, and a Generated HAL

Sweet! The Teensy might be the most accessible ARM dev board right now, so this is great news for embedded rust.

Ever since Rust was announced, I've been eagerly awaiting it's practicability as a replacement for C/C++. The only place you really have to use either of those these days is embedded systems, so this is kind of the final step towards getting modern languages in every subfield of software development.

Disagree. It's nice enough as an Arduino-alike, but it doesn't have any debugging capabilities -- the only commands exposed by the loader[1] are "write block" and "reboot".

As an ARM development board, I'm much more a fan of ST's Discovery series[2]. Most of their boards are in the $10-$20 range, and they all include a USB-based programmer/debugger compatible with open-source tools.

I second this. The STM32 discovery series boards are really great for messing around with!

Unless you are doing it for work, there are alternatives although not as safe as Rust.
