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.

Is rust used for microchip coding?
There's also RTIC which is another framework that makes concurrency trivial.
- Would generators be useful for embedded?
-
Are there universities that teach Rust?
At Telecom Paris, one of the top engineering schools in France, we teach Rust to undergraduate and graduate students who specialize in Embedded Systems. They get to use Rust and RTIC on STM32 based boards, and they also use Embassy for some projects.
-
In which circumstances is C++ better than Rust?
RTIC is still going strong, they are working on a 2.0 release at the moment :). There's also now embassy which provides an async runtime (and a ton of other nice things) for embedded as well :)

eskarp: Custom design using ergogen, 3D printed case, RP2040 with Rust firmware
RTIC - RTOS and task scheduling

My negative views on Rust
That's completely incorrect. The existing ecosystem focuses on web/IO because that's were Async/Await is already being used in other languages so everyone started there. There is significant interest in writing frameworks using async rust in embedded, but the required compiler features for it are still not stable. Check out embassy. Even RTIC has experiments with async.
-
Question: Elegant way of getting a 'static reference?
But neither of them might be usable in you case. Since it looks like you're running bare-metal, a framework like RTIC can give you a initialization function and then pass "static" data to a struct that is shared between all tasks.
-
Is crate Drone already dead? Are there any alternatives? rtfm?
FYI, RTFM has been renamed to RTIC
-
My first embedded project: OpenEMC -- an embedded management controller written in Rust
The GPLv3 firmware is written in Rust using RTIC while the Linux drivers are implemented in C.

Multitasking to Arduino
In Rust there is https://embassy.dev which is an async Rust framework for embedded. It has been shipping in products for years. Can be made real-time (for some definitions of it).
There is also RTIC https://rtic.rs which is a concurrency framework for real-time systems using interrupts. IIRC the car industry is interested in it.

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.
