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.

1.5st project: Rusty Stopwatch
I would personally use the abstractions provided by the stm32f4xx-hal crate more. See https://github.com/stm32-rs/stm32f4xx-hal/tree/master/examples/ for examples.

[Media] To get familiar with embedded Rust, I wrote a Tetris clone! It's running on an STM32. I repurposed a board I designed for another project
For this project, the audio ended up being the biggest challenge. I spent a few days on-and-off working on it because it would stop working as I modified the PWM frequency. I was eventually able to track it down to a bug in the HAL and opened a PR accordingly: https://github.com/stm32-rs/stm32f4xx-hal/pull/555

Hey Rustaceans! Got a question? Ask here! (30/2022)!
For my specific issue, I'm using the stm32f4xx-hal library to control a bunch of RGB leds, each with a pwm output. Since I have to get pins and timers where I can find them, each component of the led is made by something like

STM32F4 Embedded Rust at the HAL: PWM Buzzer
At the time of writing this post, I noticed that if going with option 1 stated earlier that returns a PWMChannel can prove to be quite problematic. In navigating the documentation, the PWMChannel implementations do not include methods that allow to get and set the period of the peripheral. There is an issue that I submitted here for that.

blink sketch for stm32f411?
Maybe check out this example from the stm324xx-hal repo?

can u reccommend a microcontroller for my protorypes needs?
Here is an example for stm32f407 (trivial to change to stm32f411) that gets random numbers from the rng peripheral and displays them on an ssd1306 display: https://github.com/stm32-rs/stm32f4xx-hal/blob/master/examples/rng-display.rs although this uses Rust, which you may or may not like. Arduino will have you covered as well, obviously.

Learn a new language after C. Rust or C++?
A major benefit of Rust in embedded is how easy it is to use libraries. This example implements USB serial communication on an STM32 in under 80 lines. You add some libs and if it compiles it works.

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

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
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...
