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.

Why did you switch from another language to Rust? Do you regret not learning it earlier?
Fast-forwards some months and I didn't even start prototyping the VM, lol. I only posted the xorsum crate. I fell in love with the type system (except for the fact that TypeScript union types are more intuitive), and the fact that I could finally manage memory manually (but in an implicit way, thanks to the borrow checker) made me feel more powerful and in control of my code (it also made me feel entirely responsible for the memory use of my software)

Hey Rustaceans! Got a question? Ask here! (30/2022)!
I made a fork of your repo, and added a commit here which makes some changes to how the data is processed. The xor_hasher function now takes in two byte slices, and main.rs now has an extra function which does some handling of the buffers.

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.
