LIN Driver Design for a Master Node Based on Freescale's MCU

Abstract

this paper describes a method of LIN master node design for a car body control system. The method based on LIN 2.1 protocol, and giving a specific process respectively on hardware and software. It expounds the implementation of LIN drive from data link layer and application layer, and describing how to realize the data link layer based on state machine. Then it introduces the communication management and signal accessing. Finally it uses hardware and Emulin to design a test. Through this test, the LIN master drive is verified in accordance with LIN 2.1 protocol.
