DataFlash_APM1.cpp - DataFlash log library for AT45DB161
Code by Jordi Munoz and Jose Julio. DIYDrones.com
This code works with boards based on ATMega168/328 and ATMega1280/2560 using SPI port

Dataflash library for AT45DB161D flash memory
Memory organization : 4096 pages of 512 bytes or 528 bytes
Maximun write bandwidth : 512 bytes in 14ms
This code is written so the master never has to wait to write the data on the eeprom
Methods:
Init() : Library initialization (SPI initialization)
StartWrite(page) : Start a write session. page=start page.
WriteByte(data) : Write a byte
WriteInt(data) : Write an integer (2 bytes)
WriteLong(data) : Write a long (4 bytes)
StartRead(page) : Start a read on (page)
GetWritePage() : Returns the last page written to
GetPage() : Returns the last page read
ReadByte()
ReadInt()
ReadLong()
Properties:
