CAN Bus: A Beginners Guide Part 1

This is the first of a two part series on the CAN Bus. In this video we will take a look at the physical aspects of the CAN Bus and the protocol itself.
Part 2 Here.

One of most important features of the CAN bus is it's noise immunity. It can operate in very noisy environments where other protocols fail. That's it's primary strength. Cars are very noisy electrically - especially the ground.

I am very impressed with the way this guy breaks down all of the information in this video. He should teach for a living 👍

this is mind blowing,
every time it is explained,
sheer genius

[evanscj]

In the Controller Area Network (CAN) protocol, 0 is dominant because it's actively driven to a voltage by the transmitter, while 1 is recessive and passively returned to a voltage by a resistor. This is the opposite of the traditional high and low used in most systems. 


I added this from Google because I wasn't sure why zero had priority

Other than that you explained the CAN bus great

[manitoublack]

Thanks for these short videos. They're a great heads up on how these systems work.

[kkfh]

This is one of the best overviews of CAN I've ever seen. Thank you!

[netgrok]

Brilliant. Thank you. Just the part about why differential pairs are immune to noise is worth the price of admission.

while i just randomly choose your video and going though it for just 15 min, Man you are just amazing, what an explanination. 👏👏👏

[alexbolin]

This video is awesome thank you so much for your time making it. I'm a industrial highspeed door installer and the manufacturer we work with has just added CAN protocols to there doors for all of the safety, accessories and communication systems for the doors and are having major issues with it and this helps me understand the system better and to help the manufacturers R&D come up with some solutions

[peteZ]

Thank you, very good lesson for someone like me that knew nothing about CAN or any other types of bus before watching.

[Paddington]

I don't use CAN bus very often at at all but this was a wonderful and very interesting video from a general electronics point of view. Thanks.

[alibro]

Brilliant video, thanks for sharing.
In my (limited) experience CAN gets very flaky when we don't follow the rules for termination and stub length. Often it will work with long stubs and extra termination resistors but be unreliable.

[nigelshepherd]

That was absolutely brilliant, well explained... I'm a hgv fitter that has been out of the trade for 20yrs...I feel like I have a understanding of can bus...thank you...👌👍

[parrotraiser]

Thank you. I've been watching CANBUS for a long time with great frustration at being unable to find proper documentation. Ad hoc rules are all very well, but it's hard to do serious thinking about a system you cannot grok. Just considering wheter it's appropriate to a problem requires understanding.

[robbieraychannel]

Best video I have seen on this subject, Thank you for taking the time to post it.

[kevinikola]

Very informative, thank you!! The arbitration is interesting. I work with this on a daily basis and now I know why an ABS module id was changed to 7E6. This gives it a much higher priority as it should be.

[Ahmadiftikhar-xx]

You just won my subscribe and my heart with your detailed explanation and the oscilloscope example!

[bandaralfoaim]

Thank you George. The vid was very easy to understand for beginners such as me. I appreciate it.

[shitmyhellcatsays]

One of the best videos on explaining this topic. Very well done.

[thomasmckeane]

Fantastic explanation of CAN BUS. The section on arbitration is very well laid out and lacking in other tutorials
