I am currently working on a deeply embedded C++ application that requires simultaneous connectivity via UAVCAN/CAN and UAVCAN/serial. Since we don’t have libuavcan yet, there is at the moment no readily available solution to implement UAVCAN/serial on an embedded target. Therefore, I am considering creating a very simple library that will implement UAVCAN/serial using virtually the same API that is provided by libcanard. I expect it to be only ~500 LLoC large because there are no multi-frame transfers to worry about (they account for most of the complexity hidden in libcanard). I am planning to name it `"libcanard".replace("can", "ser") == ` **libserard**. ---

it’s a knife lib because it’s serrated! ---

When do you expect to have a github repository available? ---

Sounds very useful! Do you have already a github repository available or is it still under construction? ---

Still under construction, unfortunately. ---

Apologize for the necro, but is there anything more current on a c-based serial implementation? I’m considering using OpenCyphal in a point-to-point network for talking to devices (that normally use CAN) over a serial port from a host PC for simplified testing. ---
