1.25 SERCOM SPI EEPROM Read Write

This example application demonstrates how to use the SERCOM SPI peripheral to write and read from the SPI serial EEPROM memory.

Description

This example uses the SERCOM SPI peripheral library to write an array of values to the SPI Serial EEPROM and verify the value written by reading the values back and comparing it to the value written.
