The Lin (Local Interconnect Network) protocol is a serial system bus used primarily in the automotive
industry that complies with the ISO-17987 standard. This is a reliable and economical communication
protocol that allows the vehicle's on-board computer to communicate with its subsystems.
There are 2 main LIN families: LIN1 and LIN2. They are essentially
differentiated by the way their messages are encoded. Those two
families can generally operate at two transfer rates: 9600 or
Within the LIN protocol, we each find five types (1, 2, 3, 4 and 5)
with five different versions (a, b, c, d and e). Those variants
allow systems to identify problems, send feedback and
information or to drive.
A communication using the LIN protocol consists of a series of frames that send a
specific message, such as alternator identification or diagnosis.
