  I've been ramping up on the embedded Rust ecosystem over the last few weeks. I'm pretty excited about it partly because it makes this aspect of embedded development much more approachable. On https://crates.io I can usually find a driver for whatever peripheral I want to use in my project. And the driver usually implements the embedded-hal [1] interface, so the more I get familiar with that interface, the easier it becomes to implement any arbitrary peripheral into my project. In the event that there does not already exist a crate for my peripheral, I have an extensive ecosystem [2] of open source driver code that I can refer to in order to figure out how to implement the driver.

  I think this could help with the "dark art of reading datasheets" problem. E.g. last night I was curious about how the driver for a 28BYJ-48 stepper motor would work, so I looked at the code [3] for its driver and got a pretty good sense of what's going on. If I were to now attempt to read the datasheet, a lot of it would now make sense. In other words I think it's too daunting to read a datasheet and then try to implement code. The way to get comfortable with datasheets is to first look at code and then find the relevant parts of the datasheet.

• Announcing the new async-hal! Featuring embedded IO traits and new interrupt-based executor
  4 projects | /r/rust | 8 Jun 2023

  What is the difference between this and https://github.com/rust-embedded/embedded-hal/tree/master/embedded-hal-async?

• Introducing async-hal! A hardware abstraction layer for embedded devices with futures
  1 project | /r/rust | 26 May 2023

  Maybe worth mentioning if you (or someone else) hasn't seen it before, the embedded-wg is also working on an async version of the embedded-hal traits, embedded-hal-async.

  In that case you want to keep most of the unsafe in the HAL crate, and expose an interface as safe as possible. To give you an idea, is it since 2018 that a "generic" DMA safe implementation is in discussion https://github.com/rust-embedded/embedded-hal/issues/37

• Stop Comparing Rust to Old C++

  Does something like embedded hal exist in the C/C++ world? ( https://github.com/rust-embedded/embedded-hal )

• not entirely new to rust, but very new to rust+arduino,.... eli5 the differences between these projects?

  worth mentioning also is embedded-hal but my understanding is this has absolutely nothing to do with arduino, so despite being embedded probably not what I want.

• Google announce secure Rust-based OS for embedded system

  The ecosystem is great and growing, It really benefits from a language-standard embedded HAL which makes writing cross-platform drivers a cinch - e.g., you can write a bit-banged MDIO driver and use it on anything that has a timer and a two IO pins, from a Zynq Ultrascale to an arduino. Sure, this is possible in C - but Rust really benefits from a less fragmented ecosystem here.

  Have you thought about writing/contributing to embedded-hal compatible crates (a sensor module driver for example)? It's always good to contribute to an eco system.

• STM32F4 Embedded Rust at the HAL: GPIO Button Controlled Blinking

  📝 At the time of writing this post, it came to my attention that there is an additional HAL that targets STM32 device families (the stm32-hal). From what I figure, right now there seem to be two approaches for developing HALs. The first approach is trait driven so to speak where the embedded-hal is used as a foundation. The second approach is more application-driven and provides a high-level API that targets several families of a device. However, this exists only for the stm32 through the stm32-hal. Right now, the first approach is what I found to be more widespread as it covers different microcontrollers and what this post is based on.

• Why doesn’t V8 fit on my microcontroller?

  I can write a library for an OLED device that is driven by an platform agnostic I2C device that will run on any microcontroller that implements the necessary abstractions.

  The `embedded-hal` (https://github.com/rust-embedded/embedded-hal) are these abstractions that allow this to happen
