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.

AVR-GCC Compiler Makes Questionable Code
Took a while but this issue was fixed this year. Until then, you could compile a patched version of LLVM, or use an older nightly.
And the code generation was quite broken indeed. Most importantly the saving of registers within interrupt handlers. Hard to understand the bug, but I had documented a simple ask inline solution on the issue. It has been fixed since then.
My last experience was quite good. And I didn't notice wrong codegen.
As an aside, the inline asm combines pretty well with generics to produce custom machine code during compilation. For example I was able to reproduce the gcc-avr built-in for delays: https://github.com/avr-rust/delay/blob/cycacc/src/delay_cycl...

Embedded Rust Development
I recently got an Arduino Uno to blink without much hassle, very excited about the 328p having built-in support. Will be even easier when a new release of a couple libraries gets released to crates.io, hopefully soon? (https://github.com/avr-rust/delay/issues/19)

Code works fine copy/pasted into my main.rs, but is ignored when run from its own external crate
tl;dr I'm trying to figure out why the avr-delay::delay function doesn't seem to do anything when imported as an external crate, but when copy/pasting the code into my main.rs, it all works. Source code here https://github.com/avr-rust/delay

Low FPS on ESP32 LCD
I'm trying lots of Rust demos (including rust-esp32-std-demo, esp32-spooky-maze-game) for ESP32 on my M5GO kit with ili9342c controller and all of them struggle to give fullscreen (320x240) frame-rate > 5.

Considerations when benchmarking on mcu?
I used this demo as a guide, it uses esp-idf for rust, and allows you to use std

Can you run rust on the new raspberry pi pico w?
rust-esp32-std-demo works quite well with WiFi, HTTPS and MQTTS. The only thing I could not make work (but I did not put much effort into it) was using async primitives. That part seems to be experimental, indeed.

Rust on Espressif chips – 15-07-2022
FWIW I've very recently gotten https://github.com/ivmarkov/rust-esp32-std-demo (which is a pretty comprehensive demo) running on a TinyPICO (w/ESP32) and am looking forward to building out my own projects next.

Is this normal bindgen/embuild behavior?
I'm using this template project to get started with the esp32, though I've started fresh in a new main function. Every time I build the project -even if I only add a blank line to main - it seems to re-compile bindgen and embuild, and regenerate the bindings for a variety of packages that have C components. I haven't made any changes to these though and the process takes a full 90 seconds. In addition nothing in the bindings that are getting generated shows up in intellisense in vscode. Any help appreciated.

Starting work using the esp32 in rust - problems and solutions. (devlog, i guess?)
This worked fairly well for me. I assume that's where the book takes you, bit I've missed if you said if you're trying to use std or no_std. https://github.com/ivmarkov/rust-esp32-std-demo
