What is LIN Auto addressing?
During auto addressing, the master sends a transmission on the LIN bus with the first slave device identification. The slave that senses that its RX pin is low accepts that ID and burns it into the EEPROM space that is reserved for ID. Then the slave device drives the TX pin to GND.
What is automotive LIN bus?
LIN (Local Interconnect Network) is a serial network protocol used for communication between components in vehicles. The need for a cheap serial network arose as the technologies and the facilities implemented in the car grew, while the CAN bus was too expensive to implement for every component in the car.
How does a LIN bus work?
How does LIN bus work? LIN communication at its core is relatively simple: A master node loops through each of the slave nodes, sending a request for information – and each slave responds with data when polled. The data bytes contain LIN bus signals (in raw form).
Where is LIN protocol used?
Modern automotive networks use a combination of LIN for low-cost applications primarily in body electronics, CAN for mainstream powertrain and body communications, and the emerging FlexRay bus for high-speed synchronized data communications in advanced systems such as active suspension.
What is LIN voltage?
The LIN bus, and LIN transceivers, typically operate at voltages ranging from 9 V to 18 V, but some go up to 30 V, depending on the application; a typical vehicle is a 12-V battery system, but some larger vehicles go up to 24 V.
CAN LIN protocols?
LIN operates under a CAN… The Local Interconnect Network (LIN) protocol specification provides a low-cost, short-distance, and low-speed network, enabling the implementation of a new level of electronics intelligence in automotive subsystems.
CAN vs LIN protocol?
LIN is a single-master multislave bus that communicates via a single wire, reducing wiring complexity as well as cost. On the one hand, CAN serves high-speed, error-sensitive needs and operates on a 5-V differential bus. LIN, however, serves low-speed, low-bandwidth requirements on a 12-V single-wire bus.
