LIN communication system is described below:
The master ECU performs the master tasks and
slave tasks, and the slave ECUs perform the slave
tasks.
When the master ECU performs a master task, the
header frame which stores information to call
certain slave tasks (ECU) is transmitted at regular
intervals.
When the master ECU and slave ECU perform a
slave task, the ECU called by the header frame
transmits the response frame which stores data
used for control.
A header and response collectively are called as a
message frame, and the communication method
that uses the message frame is called as the frame
communication.
Basically, the communication data is used with
some blocks of 10-bit data group which includes
one start bit and one stop bit (byte region) arranged
in order.
