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.

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.

Create a Custom GitHub Action in Rust
If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.

Why Does Windows Use Backslash as Path Separator?
Here's an example of someone citing a disagreement between CRT and shell32:

This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:
https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html
Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

I hate Rust (programming language)
> instead of choosing a certain numbered version of the random library (if I remember correctly) I let cargo download the latest version which had a completely different API.
Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Show HN: Fancy-ANSI – Small JavaScript library for converting ANSI to HTML
Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.
To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/
