There are a few op-codes not yet implemented, eg block erase, which is very quick. All it would now need is a reference to this updated version.

I am not an expert. In other projects Wikimedia Commons. This chip is used in a huge number of consumer electronic products.

Any microcontroller can use this chip to store data. Archived from the original on August 26, 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 found obvious and unexplained bits of code which meant it would never have worked with Arduino. These devices are now almost vintage, you may have better luck on trying for help on one datavlash the AVR forum. In the example sketch I changed the page size to and removed the buffer 2 sections. I wouldn’t expect this library to work with it.


DataFlash – Wikipedia

Views Read Edit View history. Dataflash is a specific type of flash that was made to work with Atmel chips. I suggest you copy the ccp source block of code for a similar function to your new one. However when I print the read values they are apparently random numbers except for the first value. From Wikipedia, the free encyclopedia.

Dataflash – – AVR Butterfly

I was interrupted by an official at the frontdoor halfway through last posting and forget to tidy up the example. Only change the relevant op-codethen create a new function name and create a prototype in dataflash. To moderator – the current dataflash library in the arduino playground does not work datafllash.

Hi, thanks for the library!

They use a simpler command set, supported by other vendors of serial flash but fataflash SRAM buffers and other features that make AT45 chips simpler to support.

However, one thing you will need to change in the example sketch is the number of bytes written to the buffer to match your memory size. Do you know what I should change to make it work?


Hello guys, I hope this thread is still alive so I will try to ask my question. It was developed as an Atmel proprietary interface, compatible with the SPI standard. Retrieved September 27, I have done nothing more than go through the files line by line checking what the actual code does. There are a few op-codes not yet implemented, eg block erase, which is very quick.

DataFlash is a low pin-count serial interface for flash memory. I have re-written the playground dataflash library so it works. All it would now need is a reference to this updated version.

I have fixed those parts and now it does. I also know how to connect one single DataFlash memory with the 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.
