1.15 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 on-Board AT24MAC402 EEPROM device.
