Thank you so much. That was really helpful. I am trying to communicate with the OBD II port using microcontroller. I have managed to communicate it with CAN. Now trying to communicate with LIN (Kline). I am confused what is the purpose of L-Line? I could not find any documentation for L-Line.
I think The number of slaves connected in LIN communication is 16 correct but the explanation is not correct , because PID is 6bit + 2 bit parity so it is not releated to number of slaves , as the same ID can be used by multiple slaves for communication . The explanation for having 16 slaves only is : in diagnostics the first byte of messagercalled NAD == Node Adress which is 8 bits (1 byte) which defines node adress in the network . so this will have only 16 adress .Thats the reason there are only 16 nodes which can be conneted in LIN network.
Hi Venkatesh, This is regarding the question that how many nodes to be connected to LIN master on LIN bus. As per your explanation, you said that there are 4 bits present in PID which indicates information about the node. In PID we have 6bits dedicated for ID and remaining 2 bits for parity bits.. could you please let me know which 4 bits are responsible for node information in the PID field.

Thanks Sir It helps me lot
Yes it's highly helpful Mane sir
Well explained. Please make a similar one for UDS and CAPL
Can you please make details videos on LIN protocol

same doubt I am having....
Please improve the audio quality if possible.
Sure, thank you for the feedback
