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 choose async/await over threads?
thanks. looked that up. for the curious: https://embassy.dev/

Accessing the Pinecil UART with Picoprobe
Running the Embassy RP2040 USB CDC ACM serial example takes about 5 seconds on a Pico.

Avoid Async Rust at All Cost
Async solves different problems, you can, for instance, have just a single-threaded CPU and still have a nice API if you have async-await. It might not be so cool at a higher level as Go's approach of channels and threads, but it's cool in embedded, read this:
https://github.com/embassy-rs/embassy?tab=readme-ov-file#rus...
"Rust's async/await allows for unprecedently easy and efficient multitasking in embedded systems. Tasks get transformed at compile time into state machines that get run cooperatively. It requires no dynamic memory allocation, and runs on a single stack, so no per-task stack size tuning is required. It obsoletes the need for a traditional RTOS with kernel context switching, and is faster and smaller than one!"
I'm just toying with Raspberry Pi Pico and it's pretty nice.
Go and Rust have different use cases, the async-await is nice at a low level.

Is anyone using coroutines seriously?
I have not yet dipped by toes in the Rust waters, but reading about the embassy project is actually what piqued my curiosity about using C++ coroutines in embedded. Are you familiar with the project or have you found it lacking?

The state of BLE and Rust (no_std)
I think I get the basics (shoutout to the Rust Embedded Working Group!), and I've started looking for the stack I'd be using. I think Embassy is really amazing, as well as the work of the ESP team -- hats off.

And this is how to do it using embassy, which is an async framework for embedded in rust:

The State of Async Rust
> not good for embedded
embassy begs to differ
https://embassy.dev/
async/await is really just a syntax for building state machines in a way that resembles regular code. It's compiled down to the same code that you would write by hand anyway (early on it had some bloat in state size but I think it's all fixed now).
And embedded has a lot of state machines!

Asynchronous Rust on Cortex-M Microcontrollers
You can run multiple executors at different interrupt priority levels (with multiple tasks per executor), which allows tasks on the higher priority executor to interrupt other tasks. Here's an example https://github.com/embassy-rs/embassy/blob/main/examples/nrf...

rust the compiler, hell no.
But there is an llvm-mos project to generate 6502 code and that can be used to cross compile rust code.

It was possible thanks to great https://llvm-mos.org/wiki/Welcome project (it adds 6502 target to LLVM). Adding 6502 support to rust was easy part :] https://github.com/mrk-its/rust-mos

LLVM-MOS 6502 Back end [pdf]
This is a super fun project to play around with. I'm currently trying to build a C64 sprite multiplexer in mostly straight C++ using LLVM-MOS and while it's definitely not going to be the most optimized multiplexer out there, I'm finding it most adequate performance-wise.
Whereas it's probably a long way away from being able to use this for democoding due to the mostly cycle-accurate nature of the effects, for creating homebrew games and utilities this is really quite suitable: write high-level logic and sprinkle in some inline assembly here and there for the really performance critical parts.
The code that is being generated is already quite good and (on first glance) looks better than what's coming out of cc65, for instance.
There's also rust-mos which uses LLVM-MOS to compile Rust code. It unfortunately still has some issues (e.g. [1]) but that is looking really promising as well.
Kudos to all involved :)

The Rise of Rust, the ‘Viral’ Secure Programming Language That’s Taking Over Tech
The MEGA 65 doesn't appear to have shipped yet. The best data I could find is the MEGA 65 is based on a "GS4510". The "GS4510" is compatible with a "4502", which in turn is compatible with the 65CE02. The 65CE02 uses a different manufacturing process but the same ISA as the 6502, which is supported by rust-mos and lvm-mos](https://github.com/llvm-mos/llvm-mos).

Can you write for the Commodore 64 in Rust? Why yes, yes you can!
Using llvm-mos, rust-mos, a lot of time compiling compilers and support from Mariusz (the rust-mos author), I was finally able to program like it was 1982...

This fork is handy for that. It’s fun to play with, but you need to do a decent amount yourself to get it set up.

Can Rust do every low level stuff C/C++ do?
Thanks to llvm-mos project there is also working rust fork for MOS-6502: https://github.com/mrk-its/rust-mos/tree/mos_target, so you can target 8-bit atari and c64
