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.

You should try again. I think that code is verbose because of the borrowing and because you're trying to do a one-liner. I use the nrf-hal library with the nrf52840, and the code reads pretty nicely. Here's an example:

Any good examples of using embedded Rust with an existing embedded C codebase?
Reading nrf-hal source, unfortunately new does re-configure the UARTE, and there is not a new_unchecked. The solution I can think of is to duplicate the write code with nrf52833_hal::pac::UARTE0. The Uarte type does not contain any metadata, it exists purely to guard the init of UARTE.

Really good. Check out the examples in the nrf-hal repo. Also, if you don't mind forking out for some extra components the Knurling sessions by Ferrous Systems are ace.

I rewrote my Rust keyboard firmware in Zig: consistency, mastery, and fun
The embedded HAL crates do this with extensive use of macros, for example: https://github.com/nrf-rs/nrf-hal/blob/aae17943efc24baffe30b...
This solution makes sense given the constraints of Rust, but there's quite a cost in terms of compiler time and cognitive overhead to understand what is going on.
(Aside: I didn't use the HAL in my Rust firmware, that's a higher layer of abstraction; I only used the PAC crates.)
