rp-hal VS teaching-material

probably, I didn't really check it, but I found [1]. Rust has a lot of support for embedded systems, even from the companies that provide the chips, like STM and Espressif.

About the same time, I was learning Rust and discovered how it could be used on embedded targets from Low Level Learning on YouTube, the video introduced me to the amazing rp-hal crate that provides abstractions to talk to the Raspberry Pi Pico microcontroller. Getting used to the no_std mode took some time, the most challenging was not being able to collect an iterator to a container.

Well, just as I posted this, I came across the issue on Github: https://github.com/rp-rs/rp-hal/issues/525

Have a read of https://github.com/rp-rs/rp-hal/issues/257 for more info.

I've made an example for a RPI Pico (PR for the RP2040 HAL project here) .

Here's an example: https://github.com/rp-rs/rp-hal/blob/main/boards/rp-pico/examples/pico_usb_twitchy_mouse.rs

What are you on about, can you clarify? Rust can compile in no-std/embedded style just as fine (or better) than C can for basically any ARM or RISCV based processor, and quick googling shows this hal for nearly all pi needs and even MEGA65 is "as supported" (read: not at all officially by anything, fan-only) as any current C compiler. Setting up rust for a new target, so long as the code-gen is supported somehow by LLVM, LLVM plugin, LLVM IR transpiler (and maybe libgcc-jit sort of soon) is just as painful or unpainful as setting up a whole team to work via C/C++ with comparable testing harnesses. This doesn't mean easy and is an area Rust is still improving rapidly by the various enterprise agencies (Ferrous systems, Oxide, more I can't remember...) who specifically want to bring rust to such low end hardware because frankly both C and C++ suck with vendor proprietary tool chains and quirks.

He says he can't find crate for 'bare_metal'. He was setting up and testing the HAL for the pico (https://github.com/rp-rs/rp-hal). While compiling it pulls down critical-section-0.2.7/src/lib.rs and bars on line 7

To be honest they say to contact them. "For this role, we’re asking people to write us a small proxy that does just a couple of interesting things (we’ll tell you more). " You can get experience in what you invest time into, kinda, if you make an http cli client, you'll know how to make one. Take a look at Ferrous Systems or PingCap's open workshops

Rust Book + documentation + https://m.youtube.com/c/JonGjengset/videos + https://github.com/ferrous-systems/teaching-material + https://github.com/RalfJung/rust-101 shud keep you busy

You can base the training on https://ferrous-systems.github.io/teaching-material/index.html

Thanks for the highlight! BTW, most of the material got moved to https://github.com/ferrous-systems/teaching-material/
