1.6 I2C EEPROM Driver - AT24 EEPROM Read Write
This example application demonstrates 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 the I2C based AT24 series of EEPROMs to perform read and write operations.
The application communicates with the EEPROM 3 click board that has AT24CM02 EEPROM on it.

Setting Up PIC32CXMTSH-DB Evaluation Kit
- To run the demo, the following additional hardware are required:
- Install an EEPROM 3 click board on to the mikroBUS Xplained Pro board
- Connect the mikroBUS Xplained Pro board to the Xplained pro header of the PIC32CXMTSH-DB 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
