Application note

LIN communication with two STM8AF boards

of STM8A-DISCOVERY

Introduction

This application note describes a LIN demonstration. One STM8AF board is configured as a

basic LIN master node, while the other STM8AF board is configured as a basic LIN slave

node. Each board is connected through a single wire LIN bus, thanks to the LIN transceivers

embedded in the L99PM62GXP device.

Please read the AN4101 first, which describes the demonstration delivered with the STM8A-

DISCOVERY.

You can use all these examples as a reference for understanding how to configure

LINUART, and how to implement your own LIN driver in STM8AF microcontrollers.

Note:

A LIN Software Package and a J2602 Software Package are available for free from

STMicroelectronics. Please contact your STMicroelectronics sales office for details.
