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.

Where my STM32 Rust compiler?

174 dependencies to get the temperature. Still worth it
/uj The SVG usage looks to be in a visualisation helper. Maybe ought to be a separate module, but I've seen worse.

probe-rs 0.13.0 is out! π
There is a command to list supported chips for *flashing* in all our CLI tools. Furthermore https://github.com/probe-rs/probe-rs/tree/master/probe-rs/targets contains all targets for which we support *flashing*.

Oxide on My Wrist: Hubris on PineTime was the best worst idea
Under the hood, cargo-embed, knurling's probe-run, and Humility are all built atop probe-rs (https://probe.rs/) to provide debugging - I think in this case it's actually a great example of cooperation between projects! Probe-rs has received PRs from both Knurling and Oxide devs; it provides the common interface to use various types of debug hardware and talk to various types of microcontroller cores, essentially replacing OpenOCD.

Rust on M1 What experience?
Ryzen 3700X, 3200Mhz DDR4 tower builds http://probe.rs in 1m47s with fans fully spinning. M1 Pro: zero noise, 1m21s. Ryzen 3950X is on par with the M1 Pro. Actual speed difference will very much depend on your actual workload. Compiling for aarch64 apparently is more efficient than for amd64. Which is why compiling for you locally gives much more speed benefit than some generic benchmarks would indicate :) Also, you cannot forget that I can easily work for 10hrs on my MBP M1 Pro with rust-analyzer and frequent compiles running. You can forget that with any other suggested "on par" notebook. They will drain your battery instantly. Also, with the same thermal mass, other laptop builds will go into throttling much faster, which will lead to slower effective speed. XPS laptops and old macbooks know this issue very well :)

Async Rust vs RTOS showdown! - Spoiler: Rust is faster!
Anyone who fancies doing some coding for fun should have a go at an embedded project using rust's tools. Not just embassy, but the PACs, the HALs, probe-rs (probe-rs is bonkers good), and the community on matrix. My bet is on rust embedded seeing huge growth in the next few years.

C Is Not a Low-level Language: Your computer is not a fast PDP-11.

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

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.

The State of Async Rust
> not good for embedded
embassy begs to differ
https://embassy.dev/
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...
