Hello,everyone!  
Our customer would use UAVCAN v0 for their product communication,we shall provide them with our motor driver,which should support UAVCAN protocol. For now, I have learned that libcanard([https://github.com/UAVCAN/libcanard](https://github.com/UAVCAN/libcanard)) is a good lib for developing,but it is for UAVCAN V1 version only.  
So I want to know if it(libcanard) could be ported to fit the V0 protocol？And what are the main changes? The hardware platform is a TI chip F28388X.  
Thank you in advance!

Hi!  
I’ve used libcanard for v0, but with some minor bug-corrections. libcanard for v0 was broken a while ago.  
I believe v0 is located here [https://github.com/UAVCAN/libcanard/tree/legacy-v0](https://github.com/UAVCAN/libcanard/tree/legacy-v0)

Regards

Hi!

The main code example demo.c in the “libcanard-0.2\tests” folder is very long… There is another example? I’m stuck in the canardGetLocalNodeID() function.
