Should this library work with this chip? Could you help me make this work? Perhaps a moderator can substitute this updated Atmel dataflash library and example on the Arduino Playground? Hi, thanks for the library! To moderator – the current dataflash library in the arduino playground does not work properly.

I tried the example, but it is not working.
Sorry I can’t give you the answer off datalash 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. Both are available in small 8 pin packages.
‘How to use Atmel Dataflash New Library That Works!’
Could you help me make this work? Retrieved from ” https: Hello guys, I hope this thread is still alive so I will try to ask my question. Archived from the original on August 26, I hope you can now find and check out those lines of the relevant loop code which fill the buffer and then read back. 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.
Any microcontroller can use this chip to store data. FYI I checked the Opcodes for: However, it looks like you still may be in luck. I included my sketch below and the serial output. In other projects Wikimedia Commons.
Dataflash – – AVR Butterfly
From Wikipedia, the free encyclopedia. Should this library work with this chip? I have re-written the playground dataflash library so it works. I have armel nothing more than go through the files line by line checking what the actual code does.
Retrieved September 27, 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. These devices are now almost vintage, you may have better luck on trying for help dwtaflash one of the AVR forum.
Wikipedia articles needing clarification from September All articles with vague or ambiguous time Vague or ambiguous time from September Well, I mean I probably would. Dataflash is a specific type of flash that was made to work with Atmel chips. There are a few op-codes not yet implemented, eg block erase, atmek is very quick.
I wouldn’t expect this library to work with it. 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.
Perhaps a moderator can substitute this updated Atmel dataflash library and example on eataflash Arduino Playground? To moderator – the current dataflash library in the arduino playground does not work properly.
Hi, thanks for the library! However, like many other things in that originally Atmel library, it is flakey.
Microchip® Advanced Software Framework
Just a reminder if you choose to do that. The protocol interfaces are very similar; atmrl both cases, bytes are written or read, via SPI, one or more bytes at a time.
All it would now need is a reference to this updated version. License discussion of dataflash. Also the same change needed when reading back those test values.
