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?
-
RTIC (The hardware accelerated Rust RTOS) releases v2.0.0!
Github here: https://github.com/rtic-rs/rtic
-
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.
-
When is the right time to change jobs?
If you want something more cutting edge. Try embedded Rust and checkout RTIC. I don't know if it's the real next thing. But i guess it could be fun to try.
-
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 :)

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

Why choose async/await over threads?
thanks. looked that up. for the curious: https://embassy.dev/

Accessing the Pinecil UART with Picoprobe
Running the Embassy RP2040 USB CDC ACM serial example takes about 5 seconds on a Pico.

Avoid Async Rust at All Cost
Async solves different problems, you can, for instance, have just a single-threaded CPU and still have a nice API if you have async-await. It might not be so cool at a higher level as Go's approach of channels and threads, but it's cool in embedded, read this:
https://github.com/embassy-rs/embassy?tab=readme-ov-file#rus...
"Rust's async/await allows for unprecedently easy and efficient multitasking in embedded systems. Tasks get transformed at compile time into state machines that get run cooperatively. It requires no dynamic memory allocation, and runs on a single stack, so no per-task stack size tuning is required. It obsoletes the need for a traditional RTOS with kernel context switching, and is faster and smaller than one!"
I'm just toying with Raspberry Pi Pico and it's pretty nice.
Go and Rust have different use cases, the async-await is nice at a low level.
-
Is anyone using coroutines seriously?
I have not yet dipped by toes in the Rust waters, but reading about the embassy project is actually what piqued my curiosity about using C++ coroutines in embedded. Are you familiar with the project or have you found it lacking?
-
The state of BLE and Rust (no_std)
I think I get the basics (shoutout to the Rust Embedded Working Group!), and I've started looking for the stack I'd be using. I think Embassy is really amazing, as well as the work of the ESP team -- hats off.

And this is how to do it using embassy, which is an async framework for embedded in rust:

The State of Async Rust
> not good for embedded
embassy begs to differ
async/await is really just a syntax for building state machines in a way that resembles regular code. It's compiled down to the same code that you would write by hand anyway (early on it had some bloat in state size but I think it's all fixed now).
And embedded has a lot of state machines!

Asynchronous Rust on Cortex-M Microcontrollers
You can run multiple executors at different interrupt priority levels (with multiple tasks per executor), which allows tasks on the higher priority executor to interrupt other tasks. Here's an example https://github.com/embassy-rs/embassy/blob/main/examples/nrf...
