ruduino VS rust-arduino-helpers

I've discovered that Ruduino has become quite usable in the meantime, so I was able to remove a lot of low-level port writes and unsafe code in favor of their nicely packaged Ruduino equivalents.

Rust language shares all advantages of efficient C++ code. With the rust community growing year after year, more and more people try using rust to program their Arduino boards. Consequently, the Arduino Rust ecosystem have significantly developed in the last couple of years. The Hardware Abstraction Layer for AVR microcontrollers avr-hal, Rudino library and ravedude CLI utility to make Rust development for AVR microcontrollers easier are just a few examples of the solid foundation developed so far.

It already works on Arduino. You can use https://github.com/avr-rust/avrd for register level access akin to AVR-GCC or https://github.com/avr-rust/ruduino a little bit higher level access. If you want high level "safe" interfaces you can use: https://github.com/Rahix/avr-hal

Third-party library availability is, however, still lagging behind. Luckily enough, Rust supports nearly seamless interaction with the C code! While it is very well possible to link almost any Arduino library to the rust project, I was not able to find any meaningful description of the steps required to do so! My best hit was the rust-arduino-helpers project. Despite that the code quality is, unfortunately, not great (it contains large fragments of commented code and was not updated for a while), it was a great help for me to find the right direction.
