1.7 I2C EEPROM AT24 Driver - EEPROM Read Write

This example application shows how to use the AT24 driver to perform read and write operations on AT24 series of EEPROM.

Description

This example uses the AT24 driver to communicate with I2C based AT24MAC402 series EEPROMs to perform write and read operations.
