52.12. SEI Slave: Simulate NIKON Encoder

52.12.1. 概述

• 该工程主要演示通过SEI接口模拟NIKON编码器，产生编码器位置数据等，并通过串口将信息打印出来。

• 模拟的NIKON编码器的型号为MAR-MC42AHN00。

52.12.2. 配置

• 需要两块开发板，一块板子作为Master，一块板子作为Slave。

• Master的sample的路径为：samples/drivers/sei/master/nikon，Slave即为本示例。

• 将Master的SEI接口信号DATA_P/DATA_N与Slave的SEI接口信号DATA_P/DATA_N相连接。

• 将Master的GND与Slave的GND相连接。

52.12.3. 运行现象

• 将程序下载至开发板并运行，可通过串口终端查看开发板输出的log信息，ST数值每次加1。
