In this video, we will be working on the protocols that are implemented inside the CAN bus. We will understand how message requests are granted based on priority and what factors can affect the message transfer. We will also see how a node can act as a transmitter or a receiver. The video also talks about all the four frames that the CAN bus has, which are data frame, remote frame, overload frame, and Error frame. We will also discuss how to handle these frame errors and will have a quick look at some additional features that VisualSim provides.
