SEI Slave: Simulate BISSC Encoder
==================================================================

概述
------

该工程主要演示通过SEI接口模拟BISSC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。

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/bissc，Slave即为本示例。

- 将Master的SEI_CLK跨针跨至Master侧，将Slave的SEI_CLK跨针跨至Slave侧。

- 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SEI接口信号CLKO_P/CLKO_N与Slave的SEI接口信号CLKI_P/CLKI_N相连接。

- 将Master的GND与Slave的GND相连接。

运行现象
------------

- 通过串口终端查看到的log如下，ST数值每次加1，两次采样间隔时间为200ms。
