This library is based on several projects:
|
||
|
||
The Arduino EEPROM library found here:
|
||
http://arduino.cc/en/Reference/EEPROM
|
||
|
||
The 24C256 library found here:
|
||
http://www.arduino.cc/playground/Code/I2CEEPROM
|
||
|
||
The 24C512 library found here:
|
||
http://www.arduino.cc/playground/Code/I2CEEPROM24LC512
|
||
|
||
Our project page is here:

|
||
|
||
From the datasheet:
|
||
|
||
The AT24C1024B provides 1,048,576 bits of serial electrically
|
||
erasable and programmable read only memory (EEPROM) organized
|
||
as 131,072 words of 8 bits each. The device’s cascadable
|
||
feature allows up to four devices to share a common two-wire
|
||
bus.
