esp-idf-hal VS stm32-nucleo-f401re

HALs with std support: This is exclusive to ESP32 devices right now.

Hey everybody, I'm Santiago a software engineer who recently pick interest on microcontrollers, I have been looking around the ecosystem and everything seems to be written in C/C++, nonetheless I saw this project esp-rs on github and I was fascinated and at the same time confused, I've never written any HAL or even dive into system programming.

📝 Although I followed the documentation to set up my first project, it wasn't all smooth sailing. It was mainly had to do with configurations/settings of configuration (toml) files. I figure this has to do with embassy still being considered to be experimental. Set up I managed to get working is available up in my git repo.

https://apollolabsblog.hashnode.dev/ has a lot of embedded rust, mostly tutorial style.

Here is the full code for the library/abstraction implementation described in this post. You can additionally find the full project and others available on the apollolabsdev Nucleo-F401RE git repo.

As might be obvious already, a project needs to be created, in this case, however, it's a library crate (lib.rs) that we need to include rather than a binary crate (main.rs). Additionally, I will need to configure the project for the hardware I need. To make things easier, I grabbed an existing template for a GPIO project I've created in the past and modified it. I simply deleted main.rs and replaced it with an empty lib.rs as a first step. Finally, cbindgen also requires that we add a cbindgen.toml the configuration file which can be empty for starts. Afterward, the project folder tree looks like this:

Please note that the full code in this post is available on the apollolabsdev Nucleo-F401RE git repo. Additionally, the hardware used in this post is the Nucleo-F401RE board.

All the code presented in this post in addition to instructions for the environment and toolchain setup are available on the apollolabsdev Nucleo-F401RE git repo. Note that if the code on the git repo is slightly different then it means that it was modified to enhance the code quality or accommodate any HAL/Rust updates.
