Sorry this took me so long to get posted publicly. Here is the start of what I’ve been working on. I’ve already defined an interface for the library, but am still working on the actual implementation (progress has been slow since I’ve been doing it in my free time).
For the first iteration I was designing it to just run on a bare metal micro and then planned to go back and add optional RTOS support for project wanting to build on top of an RTOS. I had also planned to write an Arduino module for it to provide the communication using the Arduino Serial interface and an example project of how to import it as an Arduino library.

Since it sounds like there are multiple people/teams looking at this, I think it’d be great if we could schedule a virtual meeting and see if we can drive consensus on a design and a plan for implementation. I’m happy to organize that meeting if people are interested.
