How can I Analyze LIN Data on car by STM32?

[ThanhVd]

I have a sensor which send LIN message to vehicle, I want to read value of current, voltage, etc, form this message by SMT32. I connect LIN Wire to IO of MCU. How can I connect and analyze data?

I hope you did not ! LIN is 12V signal level, will damage a 3.3V cpu !

You need to connect  LIN Transceiver, maybe NCV7329, and set the serial interface to LIN mode.

 

What speed an protocol is used, you should know from sensor or vehicle data - otherwise you cannot do anything useful.

Thank you for providing the comment. 
I just started with LIN Communication. Could you please give me the example code for analyzing data sent from LIN wire in the vehicle?
Thank you
