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

Setting Up SAM G55 Xplained Pro Evaluation Kit
- To run the demo, the following additional hardware are required:
- Install an EEPROM 3 click board on the mikroBUS Xplained Pro board
- Connect the mikroBUS Xplained Pro board to the EXT1 header of the SAM G55 Xplained Pro Evaluation Kit
- Connect the Debug USB port on the board to the computer using a micro USB cable
Running the Application
- Build and program the application using its IDE.
- The LED indicates the success or failure.
- The LED is turned ON when the data read from EEPROM matches with the written data
