ESP-IDF is a pretty high-level framework on top of FreeRTOS. Both do the vast majority of the heavy lifting. Once you're working on bare metal without these fancy frameworks, things get real hairy real fast. I strongly encourage you to poke around in the lower levels of the IDF. It's equal parts fascinating and horrifying. Espressif's code is... interesting, to say the least. |

Of that, I have no doubt. I'm anxiously awaiting esp-openmac's completion, so that I can use Wifi without the ESP-IDF as a dependency. It's the only reason I pull that crate in, because I'm aware of the FreeRTOS dependency.
In my experience, one never really has to work at the bare metal layer in Rust, unless you are designing new chips yourself. All the existing microcontrollers I would think of using already have well worn hals. Truly impressive what the Rust community has accomplished.
