|
||
|
|
# Pro: The schema-specific files are already included as generated C-code, this
|
||
|
|
# makes it very fast.
|
||
|
|
# Contra: Is only a demo, does not provide an interface which could be used for decoding/encoding.
|
||
|
|
# Work in progress: Fork in https://github.com/uhi22/OpenV2Gx, to add a command line interface (and maybe a socket interface).
