i2c_eeprom

Using the Atmel 24C256 EEPROM chip with Arduino

This library implements the wire library to allow Arduino to work with the Atmel 24C256 EEPROM chip.

Steps

- Connect the EEPROM chip to your Arduino as follows

Arduino Pin	EEPROM Pin	Description
NA	1,2,3,4,7	Ground
A4	5	NA
A5	6	NA
+5v	8	NA

• Initialize the library with the chip address

i2c_eerpom ee(0x50);

read(unsigned int eepromAddress)

write(unsigned int eepromAddress, byte inData)

update(unsigned int eepromAddress, byte inData)
