However, it looks like you still may be in luck. Well, I mean I probably would. FYI I checked the Opcodes for: I am not an expert. Dataflash is a specific type of flash that was made to work with Atmel chips. These parts with the F suffix are in full 45db16d 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.

Am I on a right way? However, like many other 4d5b161d in that originally Atmel library, it is flakey. Perhaps a moderator can substitute this updated Atmel dataflash library and example on the Arduino Playground? Could you help me make this work? However, one thing you will need to 45db1611d in the example sketch is the number of bytes written to 4d5b161d buffer to match your memory size. Interactive addressable led displays for holidays; interactive robots for fun.

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. I have found obvious and unexplained bits of code which meant it would never have worked with Arduino.


I have done nothing more than go through the files line by line checking what the actual code does. Sorry I can’t give you the answer off the top of my head, but it took weeks to unravel that dataflash library code, but also really I was only wanting to get it specifically to use the AT45DBD chip. I have re-written the playground dataflash library so it works. In the example sketch I changed dataheet page size to and removed the buffer 2 sections.

Someone has written a library for the Winbond flash you have here: Hello 45db161s, I hope this thread is still alive so I will try to ask my question.

I hope you can now find and check out those lines of the relevant loop code which fill the buffer and then read back. Thank you for your time and effort. I also know how to connect one single DataFlash memory with the Arduino: To moderator – datashet current dataflash library in the arduino playground does not work properly.

Since this is the only code in the public domain which will allow arduino to use atmel dataflash with full functionality, Dataseet have added ddatasheet splash line at the top of the cpp and dataflash.

I was interrupted by an official at the frontdoor halfway through last posting and forget to tidy up the example.

All it would now need is a reference to this updated version. I find Keywords are very useful, because spelling mistakes get spotted by their ‘plain’ text colour.

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. Hi, thanks for the library! However when I print the read values they are apparently random 45db161x except for the first value. The change to byte pages from default bytes is ‘once-only’.


Datasneet old version needs replacing with this one, then problems with dataflash can be directed to it and avoid the frustration I felt when assuming if it was on the playground and described, it must be correct code.

Eatasheet you know what I should change to make it work? 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 parts now.

These devices are now almost vintage, you may have better luck on trying for help on one of the AVR forum. Also the same change needed when reading datahseet those test values. I suggest 45db161s copy the ccp source block of code for a similar function to your new one.

Only change the relevant op-codethen create a new function name and create a prototype in dataflash. There are a few op-codes not yet implemented, eg block erase, which is very quick.

I tried the example, but it is not working. I wouldn’t expect this library to work with it. Just a reminder if you choose to do that. License discussion of dataflash.
