Thanks!
Yeah. I just updated the README to make it clearer. The new place is here:
As of right now, it is quite empty, so please navigate to the branch legacy-v0 – the code there is intended for the old version of the library but the changes necessary for its adaptation for the new Libcanard are quite minimal. I am going to migrate the driver for STM32 and SocketCAN in the short order. Speaking of SocketCAN, it’s going to be available for NuttX soon as well: SocketCAN API on a RTOS.
