Comment by Marco Alka on "Is Rust lang IoT ready?"

I am not working much on embedded at the moment, however that's because I am still waiting for upstream Arduino support (AVR-Rust).

For the best Rust documentation, check out the official homepage, they have a section about embedded.

j already summarized the situation pretty well. There are a lot of C Kernels you can use, and you can either write your own wrapper, or use a more common Kernel, like Linux, which has a target in rustc. If you pack the low-level knowledge, you can write software directly on hardware, so anything is possible.

However, there are also Kernels in pure Rust! For example Tock will enable you to write applications on ARM Cortex M processors easily.

Keep in mind, though, that the Rust ecosystem is still young and most crates are still in beta. That might be a problem for your company and you will have to consider the risks vs the benefits.

Trialbet we can, however it involves a lot of tinkering with forks and little documentation / tutorials. One of the things on the Rust Wishlist 2019 actually is good Arduino support.

At the moment, though, the AVR-Rust project tries to upstream their changes, so I guess that we will see upstream Arduino support in Q1 or Q2, with more tutorials coming afterwards.

If you didn't buy hardware, yet, I recommend going with a Cortex chip. There are lots of Arduino-like boards with such a processor, and they have quite good Rust support already.

Thank's for your explanation marco. At the moment i didn't get any hardware, have you arduino-like boards in specific to advise to me ?

Nicolas Bouhours unfortunately, I only have Arduinos. I started using them before I got on the Rust train. My first stop would be to get the hardware from the Rust Embedded Book to tinker around with and learn the ropes. It's a STM32F303VCT6 micro controller with a Cortex M4.

If you want to use a Kernel, like Tock, then you may want to go to their homepage and check out supported hardware, especially used in the docs and book. For Tock, they feature the Hail, IMIX and nRF51 DK boards. Though the IMIX is opensource and tailored to Tock, it is not yet available, however you can write a mail to a guy called Amit to get one early.
