Hi I have seen multiple post about LIN Bus but none seems to be able to provide clear information on the topic.
I am Looking for a interface Wire Diagram for TJA1020 between LIN - TTL UtART on Arduino. this Chip is out in the market but strange none in community has posted direct post on it. All lead to MCP.
I am planning to control Car HVAC via Arduino which will act at BCM Unit with the AC Control Unit onto a custom design
Auto AC Unit is presently off a Vehicle which interacts over LIN to the BCM which controls all the actuators based on inputs and sensory Data.
Use an oscilloscope to verify that data is getting through the transceiver in both directions.
If you don't have an oscilloscope then attenuate the signals and use your computer audio input as an oscilloscope.
