I2C EEPROM AT24 driver - EEPROM Read Write

This example application shows 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 I2C based External AT24CM0 series EEPROMs to perform write and read operations in Bare-Metal environment.

Downloading and building the application

To clone or download this application from Github, go to the main page of this repository and then click Clone button to clone this repository or download as zip file. This content can also be downloaded using content manager by following these instructions.

Path of the application within the repository is apps/driver/i2c_eeprom/at24/at24_eeprom_read_write/firmware .

To build the application, refer to the following table and open the project using its IDE.

Setting up the hardware

The following table shows the target hardware for the application projects.

• To run the demo, the following additional hardware are required:
  • One EEPROM 3 Click board

Setting up PIC32MK MCJ Curiosity Pro Board

• Connect micro USB cable to the ‘Debug USB’ connector(J1) on the board to the computer
• Install the EEPROM 3 Click board on to the mikroBUS Xplained Pro board
• Connect the mikroBUS Xplained Pro board to the EXT1 header (J501) of the PIC32MK MCJ Curiosity Pro Development Board

Setting up PIC32MK MCA Curiosity Pro Board

• Connect micro USB cable to the ‘Debug USB’ connector(J1) on the board to the computer
• Install the EEPROM 3 Click board on to the mikroBUS connector of the PIC32MK MCA Curiosity Pro Development Board

Running the Application

1. Build and program the application using its IDE
2. The LED is turned ON when the data read from EEPROM matches with the written data

Refer to the following table for LED name:
