EEPROM

I have created a library for Arduino Due at GitHub - sebnil/DueFlashStorage: DueFlashStorage saves non-volatile data for Arduino Due. The library is made to be similar to the EEPROM library.
The library is made to be similar to the EEPROM library. It will save non-volatile data but the flash storage is reset every time you upload a new sketch to your Arduino. Except for that exception it works the same as EEPROM for the older Arduinos. Remove power or press the reset button, the data will still be there.

Basic use:

// write the value 123 to address 0
dueFlashStorage.write(0,123);

// read byte at address 0
byte b = dueFlashStorage.read(0);

I hope you will find it useful.
