# 1.20 SPI SST26 Flash Write Read

This example demonstrates read and writing to SPI based SST26 flash.

## Description

This example uses the SPI peripheral library to write an array of values to the SST26 Flash and verify the value written by reading the values back and comparing it to the value written. The example application performs the SST26 write only once after a power on reset.
