After a period of laying the ground work on some simpler protocols in my YouTube channel, I've finally got to the point where I'm dealing with the CAN Bus Protocol. Hopefully this means that new episodes will be appearing slightly more frequently in future. For now it's a start:

I probably over stress the fact that CAN Bus has no address in its Layer 2 Frame, but it's why the protocol is so useful. Given that the OSI 7 Layer model stipulates that layer 2 frames should contain a source and destination address perhaps the CAN Bus protocol might be considered as being at layer 1.5 of the 7 layer OSI Model? Perhaps but there's no way I'm putting '1.5' into variable and function names ;)
