LIN 소개 (LIN Introduction)

INTRODUCTION LIN (Local Interconnect Network) is a low-cost serial communications protocol implemented mostly in automotive networks. It is typically used for mechatronic nodes in automobiles, but is also wellsuited for industrial applications. Users new to LIN communication often struggle with the overhead of the high layers of LIN protocol intricacies (e.g., LDF, NCF files). When in fact, the goal is to simply and quickly evaluate LIN MCUs and LIN PHYs hardware with very basic LIN message transmission. To assist with rapid prototyping, the complimentary MCC LIN Code Generator was created. When your LIN application is ready for production, customizable production-proven LIN Stacks and support are available from Microchip’s LIN design and third party partners. The first part of this application note covers the basics of LIN to provide a brief background on how it works. However, it is highly recommended that the reader is familiar with the LIN specification v2.2A (the most current specification available at the time of this publication). The second part describes a sample demonstration of the LIN protocol using the Microchip MPLAB® Code Configurator (MCC) LIN Stack Library. The default library supports PIC® MCUs that have a hardware EUSART peripheral. The latest MCC LIN updates also add support for bit-banged EUART, enhanced checksum and slave automatic bit rate detection using the bit-banged EUART.This document provides stepby-step procedures on how to generate both LIN master and slave drivers quickly and easily.

LIN은 자동차 네트워크에서 주로 사용되는 저가형 통신 프로토콜입니다. 자동차 네트워크에서도 사용되기도 하지만 산업용으로도 널리 사용됩니다.
