1.5 SPI EEPROM AT25 Driver - EEPROM Read Write

This example application demonstrates how to use the AT25 driver to perform read and write operations on AT25 series of EEPROM.

Description

This example uses the AT25 driver to communicate with the SPI based AT25 series of external EEPROMs to perform read and write operations.

The application communicates with the EEPROM 4 click board that has AT25M02 EEPROM on it.
