1.3 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 Curiosity Development Board
- To run the demo, the following additional hardware are required:
- One EEPROM 3 Click board
- Insert the EEPROM 3 click Board into the mikroBUS A header of Curiosity Board
- Insert the GP DIM on to DIM slot of Curiosity Board
- Connect the PKoB (J24) on the board to the computer using a USB type-C 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
