Please if possible can you provide more details like below 1) Why we need to give 3.5v and 1.5v for dominant. 2) What is overload frame means 3) More explanation on fault confinement, like what are the tx and rx counters for error active, error passive and bus off condition. 4) How the bus off condition will occur. 5) Different types of error frames etc.

What's the difference between CAN Controller and CAN Transceiver ? I'm using Arduino+MCP2515 CAN controller as a SENDER at one end. and Arduino+MCP2515 CAN controller as a RECEIVER at the other end. So I have connected a piece of wire to CAN Controller "H" of sender to "H" of receiver, and likewise "L" to L" of the receiver. and it's communicating now. How is it working without the transceiver !

hi everyone, I have one query regarding the error frame. if can controller detects any error, then the current message is discarded and the error frame is transmitted as per tx and RX counter. in error handling can be done two types one transmitter and another receiver. If the transmitter detected bit error then the transmitter sends an error frame. if the receiver side detects any error then the transmitter only transmits an error frame or receiver side transmits error frame.

Any node if detects error it will transmit error frame, does not matter receiver or transmitter

@nashs.42064 жыл бұрын
Good, thorough video. I have a few questions though: 1) Is the "arbitration ID" the same as "message ID"? I see different websites and resources say that the arbitration ID is used to determine which of the nodes gets priority. 2) When the arbitration process is going on, what is physically happening in the actual CAN bus wires? I know that several nodes can all attempt to transmit data through the bus if they detect that the bus is idle. I know that to transmit a recessive bit (1), the voltage levels of both the CAN-H and CAN-L lines go at ~2.5 V (so that the differential voltage is 0 V), and that to transmit a dominant bit (0), the CAN-H line goes to ~3.5 V and CAN-L line goes down to 1.5 V. I'm assuming that it is the nodes that forces these lines to go to their respective voltage values. Now, my question is, if there are multiple nodes attempting to use the bus, wouldn't there be a superposition/overlap of voltage values since each node will be forcing the CAN-H and CAN-L lines to go to different voltage values?

@@VenkateshMane Sorry I should have been more clear in my question. Okay, suppose that we have node A, and node B. Suppose that the arbitration ID of node A is 0111, and the arbitration ID of node B is 1011. Now, to proceed with the arbitration, node A sends out 0 whereas node B sends out 1. What this physically means is that when 0 is sent out to the bus, the CANH line is set to 3.5 V, whereas the CANL line is set to 1.5 V. Similarly, when a 1 is sent out to the bus, both the CANH and CANL lines are set to 2.5 V. This is where my confusion arises. Node A sends out 0, and *at the same time*, node B sends out a 1. How can the CANH and CANL lines be at 3.5 V and 1.5 V (to denote 0), and 2.5 V (to denote 1) at the same time?

Your explanation about arbitration was not 100% correct. Simply we can say that, the node which has 0 on lower bits of identifier wins higher priority. That's why air bag ECU wins the higher priority. Otherwise good. Keep going

"Lower Binary Value has higher priority". Suppose node A has 00000000 value and node B has 00000011 value in identifier bits. In this scenario node A wins higher priority because it has Os in lower order fields of identifier. Check above answer with some other useful docs. Its not like SPI. MSB first LSB next.
