I've always seen it described as B1, B2, ... B8. But, b[0]..b[7] is equally acceptable. How about we say either b[2] or B3 if we mean the third byte of the can bus message. Use the [ ] to reinforce that it is an array index? In the tesla roadster canbus notes, it has a little explanation: Bytes are numbered B1 to B8 not B0-B7 bits are numbered bit0 to bit7 Byte pairs are in little endian order (e.g B4*256+B3) Regards, Mark.

Hi everyone,
we have a little big Problem. :-)
Computer Nerds, programmer etc. start counting by 0 (zero). The CAN Bus Data Byte descriptions say D1, D2, ... , D8
Example: 5EC 8 FE 47 69 00 00 00 00 00 So, what do you mean with Byte 2? Is it 47 or is ist 69?
As a programmer i say it is 69. But other People say it is 47. Confusing!?
I think it is essential that we have one base. Lets start counting with 0. So the value from above is 69.
