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.

Help getting started with Keyberon and RP Pico
See the source code at https://github.com/rwalkr/eskarp. The layout is defined at https://github.com/rwalkr/eskarp/blob/19e4b54fd48c07b64bf8050622bdebac5622d7b1/firmware/src/main.rs#L119 - you can strip it down to what you need and adjust the column / row / layer counts at line 67. You may also need to adjust the pin numbers depending on how you've wired it up

Is rust used for microchip coding?
There's also RTIC which is another framework that makes concurrency trivial.
- Would generators be useful for embedded?
-
Are there universities that teach Rust?
At Telecom Paris, one of the top engineering schools in France, we teach Rust to undergraduate and graduate students who specialize in Embedded Systems. They get to use Rust and RTIC on STM32 based boards, and they also use Embassy for some projects.
-
In which circumstances is C++ better than Rust?
RTIC is still going strong, they are working on a 2.0 release at the moment :). There's also now embassy which provides an async runtime (and a ton of other nice things) for embedded as well :)

RTIC - RTOS and task scheduling

My negative views on Rust
That's completely incorrect. The existing ecosystem focuses on web/IO because that's were Async/Await is already being used in other languages so everyone started there. There is significant interest in writing frameworks using async rust in embedded, but the required compiler features for it are still not stable. Check out embassy. Even RTIC has experiments with async.
-
Question: Elegant way of getting a 'static reference?
But neither of them might be usable in you case. Since it looks like you're running bare-metal, a framework like RTIC can give you a initialization function and then pass "static" data to a struct that is shared between all tasks.

Is crate Drone already dead? Are there any alternatives? rtfm?
FYI, RTFM has been renamed to RTIC
-
My first embedded project: OpenEMC -- an embedded management controller written in Rust
The GPLv3 firmware is written in Rust using RTIC while the Linux drivers are implemented in C.

Multitasking to Arduino
In Rust there is https://embassy.dev which is an async Rust framework for embedded. It has been shipping in products for years. Can be made real-time (for some definitions of it).
There is also RTIC https://rtic.rs which is a concurrency framework for real-time systems using interrupts. IIRC the car industry is interested in it.
What are some alternatives?
embassy - Modern embedded framework, using Rust and async.
tock - A secure embedded operating system for microcontrollers
avr-hal - embedded-hal abstractions for AVR microcontrollers
nettu-scheduler - A self-hosted calendar and scheduler server.
cortex-m - Low level access to Cortex-M processors
cortex-m-quickstart - Template to develop bare metal applications for Cortex-M microcontrollers
blisp - A statically typed Lisp like scripting programming language for Rust.
bazel-embedded - Tools for embedded/bare-metal development using bazel
harsark.rs - A safe and lightweight real-time Kernel written in Rust.
svd2rust - Generate Rust register maps (`struct`s) from SVD files
bitsvec - A bit vector with the Rust standard library's portable SIMD API.
cudarc - Safe rust wrapper around CUDA toolkit
