This is an Arduino library for AT45DB dataflash.
The code was developed to be used for the Sodaq Moja board. But it is general purpose, so it can be used in other environments too.
Sodaq Moja has an on board AT45DB161D. An earlier development board Sodaq V2 has an AT45DB081D. You may want to check Sodaq_dataflash.h and verify that the correct variant of the AT45DB is selected. Perhaps someday we can detect this dynamically.
