CRC field calculation for CAN 2.0 B

Question

Do you have a practical example on how to calculate the CRC field for CAN 2.0 B?

Are you wondering what algorithm is used to create the cyclic redundancy check within the CAN message? I would think that is probably not only proprietary, but is different depending on which CAN controller is used. I've not done any work in this realm, so don't know for sure. — Pᴀᴜʟsᴛᴇʀ2, Aug 07 '15 at 13:37
@Paulster2 Thanks. Does the CAN standard suggest a way to calculate it? Is there a step-by-step calculation example, so I can understand exactly how it works? — , Aug 07 '15 at 13:43

Yes. Can you name one link which satisfies my question. I would be glad to accept it! — , Aug 07 '15 at 14:02
@DavidWinslow I read both already. They do not have any example how to calculate the CRC. Thanks anway — , Aug 07 '15 at 14:03
