2020-01-09converter: Improve bit_position computationRomain Forlot1-3/+4
- Fix wrong bit_position swap computed: Need to multiply then lenght in bytes by 8 to get it for bits. - Add a continental bit_position function: This allow to get the correct bit_position using the weird Continental. bit numbering method where the Frame is read using little endianness and bit count using a big endianness - Use define CHAR_BIT instead of hardcoded 8 value Change-Id: I8d458ab457f80e5fa116af942acfceaaef51b763 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>

2020-01-09message: More explicit define about CAN protocols.Romain Forlot2-4/+4
Change a bit CAN binding define about used protocol. There was a mistake about BCM define which isn't a protocol at all but a maner to filter and retrieve CAN message through SocketCAN. Also FD_FRAME was using the same name than SocketCAN which isn't a good idea, better to distinguis both of them.
