1.9 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 in Bare-Metal environment. This application uses I2C driver to read and write data from an AT24CM02 EEPROM device.

Setting Up Curiosity PIC32MX470 Development Board

  • To run the demo, the following additional hardware are required:
  • Connect mini USB cable to the ‘Debug USB’ connector(J3) on the board to the computer
  • Install the EEPROM 3 Click board on to the mikroBUS socket J5 of Curiosity PIC32MX470 Development Board
    Note: Ensure that the series resistors on the mikroBUS headers are of value 0 Ohms.

Running the Application

  1. Build and program the application using its IDE
  2. The LED is turned ON when the value read from the EEPROM matched with the written value
Refer to the following table for LED name:
