Introduction

This example demonstrates LIN Responder mode data write and read operation using LLD driver where the Instance LIN1 is set as a Responder. The transfer is initiated by PLIN-USB (from PEAK Systems -> IPEH-004052) device connected to external PC.

The LIN1 instance waits for appropriate ID. On ID match the instance responds with data then waits for Reception of a Message from remote Commander.

Example Can be run in Polling, Interrupt and DMA mode, The Operating mode is configurable in SYSCONFIG.
