# 1.4 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 on-Board EEPROM to perform write and read operations in RTOS environment. This application uses I2C driver to read and write data from an on-Board 24AA025E48 EEPROM device.

## Downloading and Building the Application

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

Project Name | Description
--- | ---
sam_a7g5_ek_freertos.X | MPLABX project for SAMA7G54 Evaluation Kit

## Setting Up AT91Bootstrap loader

To load the application binary onto the target device, we need to use at91bootstrap loader. Refer to the at91bootstrap loader documentation for details on how to configure, build and run bootstrap loader project and use it to bootstrap the application binaries.

## Setting Up the Hardware

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

### Setting Up SAMA7G54 Evaluation Kit

- Connect the USB port J7 on board to the computer using a micro USB cable (to power the board)
- Connect the USB port J24 on board to the computer using a micro USB cable (to enable debug com port)

## Running the Application

1. Build 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:
