I2C EEPROMs library for Arduino

What is it?

This library (with examples) is designed to be integrated in projects using I2C EEPROM. It can read and write data from I2C EEPROMs. It has been fully tested with 24LC256 device but should work with others.

How to install

  1. Download latest release

  2. On your Arduino IDE, click "Sketch" menu and then "Include Library > Add .ZIP Libraries"

  3. You can now use the library for your project or launch an example ("File > Examples")

How to connect I2C EEPROM to arduino

Most of I2C EEPROMs are connected the same way.

Here are the pin connections for 24LC256 device:

24LC256 Arduino Source
VCC 5V
GND GND
SCL SCL (A5)
SDA SDA (A4)
Others GND (-> I2C address = 0x50)

Examples

Three examples are provided with this library:

Simple Read through all EEPROM

Link to source code

Simple Write though all EEPROM
