1.7 I2C Driver Synchronous - I2C EEPROM
This example application shows how to use the I2C driver in synchronous mode to perform operations on the EEPROM.
Description
This example uses the I2C driver in synchronous mode to communicate with the EEPROM to perform write and read operations. This application uses I2C driver to read and write data to EEPROM 3 click board that has AT24CM02 EEPROM on it..

- To run the demo, the following additional hardware are required:
Setting Up SAMA5D29 Curiosity Development Board
- Connect the EEPROM 3 click board to the MikroBus1 (J19) header of the SAMA5D29 Curiosity Development Board
- Connect the USB_A port on board to the computer using a USB-C type cable.
Running the Application
- Build and program the application using its IDE.
- The LED is turned ON when the value read from the EEPROM matched with the written value
