atsamd VS awesome-embedded-rust

It’s definitely used for “nonsafety” stuff like infotainment. The ATSAMD HAL/PACs are probably the most complete embedded microcontroller family as far as Rust support goes, and that’s a part with heavy intent toward automotive use.

The Rust ATSAMD community has been very helpful getting me going. I've really become fond of RTIC as a way to get a little structure in my programs.

The atsamd-rs rust folks (https://github.com/atsamd-rs/atsamd) have made this way easier! Check out my top level comment!

I'm obviously biased, but as a starting point I would recommend getting an Arduino and following the process in the article. Once you have a blinking LED, try it again using a HAL like atsamd-rs/atsamd. Then try making it more complex: configure the clock and replace the delay implementation with something that takes a proper duration argument, add serial IO via the USB port so you can communicate with your program as it runs, connect some more LEDs or buttons and interact with them, or make some network requests.

The embedded-hal project supplies these for a wide variety of controllers, for SAMD specifically, https://github.com/atsamd-rs/atsamd .

No love for Microchip nee Atmel? https://github.com/atsamd-rs/atsamd

Am admittedly too inexperienced to properly weigh the pros and cons of various platforms, but I find the Rust support for certain embedded platforms to be particularly compelling.

I have at least managed to get some literal blinkenlights doing what I want on various Adafruit boards with very little effort.

Are you saying that this book is a hallucination? And this? And all of this?

Feel free to PR them to the awesome embedded rust list, and the matrix rooms for embedded rust and esp32 (linked on that page) are super active, so feel free to plug this there too :)

If you haven't already, feel free to PR it to the awesome embedded rust list!

list of curated rust microcontroller resources

embedded-hal trait-based HALs: There could be a better description than this. However, this category has the widest base of implementations with more options than can be mentioned here. A more comprehensive list can be found on the awesome embedded Rust repository.

For what it's worth, the ecosystem is definitely growing. See here: https://github.com/rust-embedded/awesome-embedded-rust, there are quite a few drivers for a pretty wide variety of sensors/periphs, and almost every large SoC line is supported.
