1.9 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 External AT24CM0 series EEPROMs to perform write and read operations in Bare-Metal environment.
