Long Message
- This content refers to the message format of UAVCAN.
- Thanks to UAVCAN
- Note:
- ID2, CRC16 : byte order : low byte first, little endian
- Reference:
CAN 2.0
- Packaging the message to be sent.
- If the message to be sent is 8 bytes or more, CRC16 is added.
- Multi Packet's Data Format
- < Data : max 7 byte, cut from packed Message >, <Check Byte>
- Check Byte
- bit 7 = 1, if first packet
- bit 6 = 1, if last packet
- bit 5 = Toggle, first packet = 1, toggle bit on each packet
- bit 4:0 = Seq, 0 ~ 31, inc 1 on each message
FD-CAN
- Under construction !
