DataFlash_APM2.cpp - DataFlash log library for AT45DB321D
|
||||
Code by Jordi Muñoz and Jose Julio. DIYDrones.com
|
||||
This code works only on ATMega2560. It uses Serial port 3 in SPI MSPI mdoe.

Dataflash library for AT45DB321D flash memory
|
||||
Memory organization : 8192 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()
