Nunavut does not produce the data type signature

Applications & Usage Nunavut
1

command: nnvg --target-language c …
The output c header files do not contain the data type signature which is used for frame crc calculation,
so how to use this dsdl tool ?

Thanks

2

UAVCAN v1 does not use data type signatures.

3

The signature is used to calculate crc in the code of c++ libuavcan and libcanard,
is there some options to make Nunavut compatible with the signature?
or which dsdl compiler can I use if the signature is needed?

4

OK, the problem is that the uavcan library I used is based on UAVCAN v0, now I want to refine the app code not using the uavcan library but only the compiled dsdl. is Nunavut compatible with UAVCAN v0?

5

Nunavut is only compatible with v1.

Thanks Pavel.
I found the v1 bit order is opposite with v0 when not byte aligned, which is not compatible.
so is there any document for the changes from v0 to v1?
