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.

Embedded Systems Weekly #110
CHIPnGo A custom-built CHIP-8 hand-held gaming console powered by a STM32 microcontroller.
- Show HN: I built a handheld CHIP-8 game console to teach myself embedded systems
-
I finished my hand-held CHIP-8 game console I call CHIPnGo!
It's essentially complete now (other than some planned firmware tweaks) and you can check out the source code on GitHub. You can also see a video if it in action here.

8-bit console - picking MCU/MPU
I ask because I recently made a console for CHIP-8 which is an old 8-bit “fantasy console” by writing a CHIP-8 emulator for a STM32 MCU. So games still have that 8-bit limitation like you’re going for but the STM32 has a bit more power than actual 8-bit MCUs which is useful for working with the display and stuff.

[Schematic Review + General Design Questions] CHIP-8 Handheld Game Console
Now that I have a nearly complete prototype for my CHIP-8 game console that I've been working on, I wanted to attempt to create a custom PCB to truly make it portable.
-
I'm working on a physical, handheld CHIP-8 game console. Anyone have suggestions/critiques?
A couple months ago, I decided I wanted to learn more about embedded software development so I thought it would be cool to port my emulator to a STM32 MCU and try to build a handheld game console since CHIP-8 never existed as an actual standalone physical machine. I have a working prototype and the firmware (which I wrote from scratch so it took quite awhile to get right) is basically done (though I will likely do some refactoring and add a bit more robustness) which can be found here. Next step is to design a PCB and add battery power to have a no-shit portable game console.

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.

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...
