CAN dominant bit

Rasul Kishov

Hi everybody.

I don't have any experience with CAN interface.

I used examples and documentation. So my Tiva C launchpad succesfully transmit and recive messages now.

But I have one question for which I didn't find an answer in docs. Which bit in CAN module is dominant: hardware "0" or "1" in message's ID?

I mean which ID will win arbitration in CAN bus: 0x000 or 0xFFF?

Hello Rasul

Dominant is "0" in CAN and a good article

Thanks! Again :)

Actually I have read russian version of this article. But in this version there is no information about physical hardware dominant bit.

Thanks again for you reply.
