Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Arduino Uno issue with interfacing with a dht11 sensor.

What are the scenarios where "Rewrite it in Rust" didn't meet your expectations or couldn't be successfully implemented?
I found the generics a lot less of a problem when I realized I could parametrize on things like embedded_hal::serial::Write instead of UsartOps https://github.com/Rahix/avr-hal/pull/264/commits/17ed15321cb8fcf8aedb1f8133be1f189eb06a6f

not entirely new to rust, but very new to rust+arduino,.... eli5 the differences between these projects?
I've come across avr-rust, avr-hal and both seem to have arduino stuff, wondering which is the most beginner friendly? (I have a bit of experience with the regular arduino IDE but want to switch over to doing all the stuff in rust for a challenge)

Hey Rustaceans! Got a question? Ask here (1/2023)!
fyi, a minor follow-up at https://github.com/Rahix/avr-hal/issues/388

Rust and arduino?
I have contributed a little to this. avr-hal I have done a couple little hobby projects with it as well, but I can't say it's the best thing out there.

Learning Embedded rust
All you need is in the documentation: https://rahix.github.io/avr-hal/arduino_hal/index.html even though reading the documentation without knowing what you're looking for can be quite difficult, so looking at some examples might be more helpful.

Five simple steps to use any Arduino C++ library in a Rust project 🦀
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.

From arduino to rust via avr-hal
There's a blink example in the repo for the avr-hal crate.

Rust GCC back end was officially accepted into the compiler
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
