CAN and CAN FD protocol

Browse our CAN and CAN FD transceiver portfolio

This lab will discuss how information is encoded and passed between devices
on the CAN bus using the ISO 11898 standard, including arbitration, frame
structure, and bit stuffing. We will also introduce CAN with flexible data
rate and discuss its benefits in application.

Very clear and comprehensive explanation. Thank you for putting so much diligence, into making the course accessible and thorough enough. Such results are achieved only with genuine dedication. Thank you very much for clear & in-depth explanation !!!

[ajaychennu]

Thank you so much 🎉
Clear explanation
Well done

[tarekmohsen]

Thank you. It is the first video from alot of videos i watched before where i understand the CAN bus

[Gattuser]

Excellent video indeed, slides and images are very helpful

[parvathik]

Precise and upto the point explanation.Thank you.

[LordPhobos]

This video ia excellent. Very clear explainations of what's happening within the protocol.

One question, what exactly does a data request frame look like? Does it have just the address requested and the RTR bit recessive, or does it have everything, with a 0 byte data section?

Thankyou again for these CANbus videos, they're really clear, and enjoyable.

[JetNmyFuture]

off to order some parts from DigiKey next system design is expected to be all CAN. Thanks for the confidence builder.

[YKibarashi]

the explanation is very good and exhaustive, I just have a question, for the error frame is it sent in the place of ACK bit

[thecannetwork]

That was excellent and such a genius technology

The arbitration relies on the nodes being synchronized but it's not clear to me whether they are synchronized at the bit level or at the frame level. Is it correct to say the synchronization works at the bit level and the start bit ensures that one node will not start transmitting after another node has started? (Obviously the arbitration is required if 2 or more nodes start transmitting at the same bit interval.)

If my car doesn’t have can FD is worth to buy an a scanner that is can fd is compatible?

[Mrnaga]

At 11:59 I didn't complely get it
For bit stuffing happens
1 1111 0 0 twice. While destuffing how it is handled ? Because while destuffing it's already destuffed the recessive bit.

Can you share a video on CAN Network Management

[Kartheek-puhm]

what is maximum interframe space can be ?

[mahmoudismail]

This is really Awesome! Are there any explanation but for Ethernet

[xealit]

but what serves as the address of the frame? Is it the priority id? Then, if a node requests data from another one, it puts the id of the addressee? What if the addressee is sending at the same time? Then the priority ids of the frames will be identical. Does it mean that the arbitration is solved by the request bit in this case? Also, in the request frame, can it include something like a "register address" from a node? Or 1 node is always only 1 source of data?

I've seen a lot of different sources mentioning that the IFS should be 3-bits long. However according to this video and some of the other TI documents, it is said to be 7-bits long. Is it intended?
