# SEI Slave: Simulate NIKON Encoder

## Overview

This demo shows SEI interface simulate NIKON encoder (Product: MAR-MC42AHN00) and generate position data, then print related information by uart console.

## Configration

- Two development boards are required, one as the master and one as the slave.
- Master sample path is "samples/drivers/sei/master/nikon", slave is this example.
- Connect master's SEI pins DATA_P/DATA_N to slave's SEI pins DATA_P/DATA_N.
- Connect master's GND to slave's GND.

## Running the example

- When the example runs successfully, the console shows the following log. ST's value increasing by 1 each sample, sample interval is 200ms.
