Introduction

This example demonstrates LIN Commander mode data read operation where the Instance LIN1 is set as a commander. The massage is initiated by LIN1 instance and PLIN-USB(from PEAK Systems -> IPEH-004052) responds with data.

The LIN1 instance initiates the transmission by sending ID in Blocking Mode.

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