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.

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.

Is statically compiling against glibc possible?
To compile a program with musl on a glibc system you can use cross-rs!

How to cross Compile on Debian for: Mac / FreeBSD / OpenBSD / Android ... ?
I cross compile to Mac, bsd, windows, etc cross ... Works great for me with either docker or podman.

Compiling against specific version glibc
If docker is available for you, https://github.com/cross-rs/cross is another and reliable way to solve this kind of problem. I do use it regularly.

A guide to cross-compilation in Rust
There is some built-in support in rustc for cross-compiling, but getting the build to actually work can be tricky due to the need for an appropriate linker. Instead, we’re going to use the Cross crate, which used to be maintained by the Rust Embedded Working Group Tools group.
-
Is there a definitive guide on cross-compiling with OpenSSL?
I have used cross before to cross compile from Linux to other Linux. It has a section on it's wiki about this. Maybe that could be of help.

Docker ARMv7 Alpine Rust builder
You can use cross to build your application and copy the artifacts into an alpine armv7 container. It would also build faster due to using cross compilation rather than QEMU.
-
Compiling Linux to Mac in CI/CD
Looks like cross is the easiest way to get something cross-compiled but its Mac support is blocked behind building your own build image. Even that repo says that it might be broken.
-
How to you develop in containers?
Bonus: if you’re working with Rust and doing a lot of cross platform stuff, check out cross. It runs QEMU in docker so you can run tests on a bunch of different emulated targets easily- literally a one line setup, it’s kind of magical.
-
What are some stuff that Rust isn't good at?
It's also not as naturally cross-compilable as Go, though that's partly a side-effect of not accepting being a semi-closed ecosystem to achieve that and cross exists as a stop-gap while things like cargo-zigbuild explore less drastic options.
