These devices are now almost vintage, you may have better luck on trying for help on one of the AVR forum. Do you know what I should change to make it work? I included my sketch below and the serial output. Should this library work with this chip? There are numerous unresolved posts which would have been easily answered and fixed by those generous individuals who give their time to assist others with their projects. However, it looks like you still may be in luck. The change to byte pages from default bytes is ‘once-only’.

Dataflash is a specific type of flash that was made to work with Atmel chips. Any microcontroller can use this chip to store data. I have fixed those parts and now it does.
I have found obvious and unexplained bits of code which meant it would never have worked with Arduino. You can easily add your own ‘block erase’ etc, just keep clear of the sector protection etc programming codes or you could brick the flash. However, like many other things in that originally Atmel library, it is flakey.
These parts with the F suffix are in full dqtaflash are available in densities from 2Mbit to 64Mbit and have an applications note to help you move from the D parts to the F parts in our FAQ section. Views Read Edit View history.

There are numerous unresolved posts which would have been easily answered and fixed by those generous individuals who give their time to assist others with their projects. All these cards can be used in SPI mode. I have done nothing more than go through the files line by line checking what the actual code does. From Wikipedia, the free encyclopedia. I hope you can now find and check out those lines of the relevant loop code which fill the buffer and then read back. DataFlash is a low pin-count serial interface for flash memory.
Could you help me make this work?
DataFlash – Wikipedia
I atmle interrupted by an official at the frontdoor halfway through last posting and forget to tidy up the example. This page was last edited on 25 Julyat Thank you for your time and effort. Firstly I must register my interest in Dataflash – I work for Adesto, the company that has taken over from Atmel and is manufacturing the Dataflash agmel now. Interactive addressable led displays for holidays; interactive robots for fun.
Hello guys, I hope this thread is still alive so I will try to ask my question. However, it looks like you still tamel be in luck.
FYI I checked the Opcodes for: I tried the example, but it is not working.
Dataflash – – AVR Butterfly
Perhaps a moderator can substitute this updated Atmel dataflash library and example on the Arduino Playground? In the example sketch I changed the page size to and removed the buffer 2 sections.
All it would now need is a reference to this updated version.
In other projects Wikimedia Commons. Hi, thanks for the library!
They datavlash a simpler command set, supported by other vendors of serial flash but omitting SRAM buffers and other features that make AT45 chips simpler to support.
Both are available in small 8 pin packages. Well, I mean I probably would.
