1.8 I2C Driver Asynchronous - I2C EEPROM

This example application shows how to use the I2C driver in asynchronous mode to perform operations on the EEPROM.

Description

This example uses the I2C driver in asynchronous mode to communicate with the EEPROM to perform write and read operations in Bare-Metal environment. This application uses I2C driver to read and write data from an AT24CM02 EEPROM device.
