1.5 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.

Setting Up PIC32CM JH01 Curiosity Pro Development Board
- To run the demo, the following additional hardware are required:
- One EEPROM 3 Click board
- One mikroBUS Xplained Pro boards
- Connect mikroBUS Xplained Pro board to EXT3 header
- Plug the EEPROM 3 click Board into the mikroBUS socket of the mikroBUS Xplained Pro board
- 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
- LED indicates success or failure:
- The LED is turned ON when the value read from the EEPROM matched with the written value
