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.

AVR-GCC Compiler Makes Questionable Code
Took a while but this issue was fixed this year. Until then, you could compile a patched version of LLVM, or use an older nightly.
And the code generation was quite broken indeed. Most importantly the saving of registers within interrupt handlers. Hard to understand the bug, but I had documented a simple ask inline solution on the issue. It has been fixed since then.
My last experience was quite good. And I didn't notice wrong codegen.
As an aside, the inline asm combines pretty well with generics to produce custom machine code during compilation. For example I was able to reproduce the gcc-avr built-in for delays: https://github.com/avr-rust/delay/blob/cycacc/src/delay_cycl...

Embedded Rust Development
I recently got an Arduino Uno to blink without much hassle, very excited about the 328p having built-in support. Will be even easier when a new release of a couple libraries gets released to crates.io, hopefully soon? (https://github.com/avr-rust/delay/issues/19)

Code works fine copy/pasted into my main.rs, but is ignored when run from its own external crate
tl;dr I'm trying to figure out why the avr-delay::delay function doesn't seem to do anything when imported as an external crate, but when copy/pasting the code into my main.rs, it all works. Source code here https://github.com/avr-rust/delay

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.

The coincidental typos compiled..
Today I was toying with the arduino again, making an attached LED matrix print awesome messages better than it previously had. I wanted to use millis() found in the examples in the unsurpassed avr-hal crate, to orchestrate the duration it should show (part of) a character before moving on. But that is all besides the point. I made a few mistakes that coincidentally compiled and as such made me believe I was doing things right. (Perhaps I should note here that I am visually impaired so it is a bit easier for me to glance over smaller differences.)

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

Hey Rustaceans! Got a question? Ask here! (34/2022)!
I'm trying to make an Arduino display text on an LCD using I2C (HD44780). So far, I've used arduino-hal from the avr-hal crate (github.com/Rahix/avr-hal) to program the Arduino, and I wonder if anyone happens to know of a library/crate which is compatible with it? So far I've only found ag-lcd which doesn't seem to work with I2C.
