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.

ESP32 Standard Library Embedded Rust: GPIO Interrupts
It's well established that interrupts are a tough concept to grasp for the embedded beginner. Add to that when doing it in Rust the complexity of dealing with mutable static variables. This is because working with shared variables and interrupts is inherently unsafe if proper measures are not taken. When looking at how to do interrupts using the esp-idf-hal I first resorted to the Embedded Rust on Espressif book. Interrupts are covered under the Advanced Workshop in section 4.3, and to be honest, I was taken aback a little at what could be an additional level of complexity for a beginner. Without too much detail, this is because the book resorts to using lower-level implementations. For those interested, by that, I mean FFI interfaces to FreeRTOS which I will be creating a separate post about later.

ESP32 Standard Library Embedded Rust: GPIO Control
Relative to the esp-idf-hal , as far as material goes, there exists training material that is open sourced by Ferrous systems. The training material takes a bit of a different approach where it starts with high-level IoT exercises followed by low-level control. Additionally, the training is based on the awesome Rust ESP board hardware.

Espressif advances with Rust – 30-06-2023
Yes! The training developed with Ferrous Systems (https://esp-rs.github.io/std-training/) contains several examples, and you can find many community projects in https://github.com/esp-rs/awesome-esp-rust#projects

Unlocking Possibilities: 4 Reasons Why ESP32 and Rust Make a Winning Combination
Good places to get started with std Rust on ESP include the Rust on ESP book, Embedded Rust on Espressif by Ferrous Systems. There's also the Awesome ESP Rust GitHub repository that contains a lot of useful material and project examples.

Why do I constantly feel like I'm doing something wrong by continuing using C++?
I must admit I've never used it for anything but tutorials yet (kids resulted in a lot of personal projects shelved), but Rust has an amazing and rapidly developing embedded ecosystem. A good starting point to get an impression of it might be training materials from Ferrous Systems 1, 2 (feel free to pay for the training itself if you feel like it's worth it for you of course). There is an embedded working group for Rust, Knurling project to improve tooling and even an attempt of Rust standard certified for safety-critical application.

Ask HN: Has any Rust developer moved to embedded device programming?
I’ve been super curious about both Rust and ESP. It seems like Espressif is interested enough to commission a Rust dev board (ESP32-C3-DevKit-RUST-1) and training using it.

OxidOS Automotive
Hi! This is Daniel from OxidOS Automotive (stating this for disclaimer purposes).
Yes, our OS is based on TockOS, and our CEO (Alex Radovici) is #7 in the contributors list (https://github.com/tock/tock/graphs/contributors), with other colleagues contributing in the past years.

Safety vs. Performance. A case study of C, C++ and Rust sort implementations
I'm definitely not the best person to answer this, but honestly it's not bad. Here's an example of a moderately complex peripheral, the cortex-m MPU, and how one rust OS handles it:
https://github.com/tock/tock/blob/3a0527d586702b8ae8cb242391...
Reads and writes turn into volatile reads, so everything works out under the hood. You get the benefits of everything having good names, declared sizes, and proper typing on your register accesses. You can extend that to bit accesses as well.
Rust still has a few areas it isn't competitive in, like your hyper limited or obscure chips (e.g. 8051s, XAP), mature tooling around formal methods, and a certification story for safety critical code. People are working on these latter two issues (e.g. ferrocene) and supposedly very close to public delivery, but you know how slow the industry is to adopt new things even then.

Real-Time Operating Systems 101: Basics for Efficient Computing
There's Tock (https://www.tockos.org/), which is written in Rust (with sprinkles of assembly).

Unwinding the Stack the Hard Way
Yeah, and I like I mentioned in the earlier comment, omitting the frame pointer reduces code size by 10% on RISC-V targets, which is huge when dealing with embedded flash: https://github.com/tock/tock/pull/1660
- Where are the C Alternatives?
-
Embedded real time OS
Tock is an excellent embedded OS written in Rust and has some good industrial support. I think Tock gets a lot of stuff right and I highly recommend some of the talks the developers gave on it.

Fedora now has frame pointers
Unfortunately, it increases the code size by 10%. I was looking into this just last week, and can confirm that it's still a problem on the latest version of Rust nightly: https://github.com/tock/tock/pull/1660
I wish we could have frame pointers, because they would make working in embedded land so much easier and more reliable, but a 10% increase in code size just isn't worth it.

Rust OS
TockOS was the first rust RTOS I found. Coincidentally, it has had support for the esp32c3 for over a year now.
