Interactive addressable led displays for holidays; interactive robots for fun. However when I print the read values they are apparently random numbers except for the first value. I was interrupted by an official at the frontdoor halfway through last posting and forget to tidy up the example.

Well, I mean I probably would. I tried the example, but it is not working. 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. The change to byte pages from default bytes is ‘once-only’. These devices are now almost vintage, you may have better luck on trying for help on one of the AVR forum.

I have found obvious and unexplained bits of code which meant it would never have worked with Arduino. Perhaps a moderator can substitute this updated Atmel dataflash library and example on the Arduino Playground? All it would now need is a reference to this updated version. Thank you for your time and effort. Dataflash is a specific type of flash that was made to work with Atmel chips. I am not an expert.

I also know how to connect one single DataFlash memory with the Arduino: Someone has written a library for the Winbond flash you have here: Also the same change needed when reading back those test values. Just a reminder if you choose to do that.

I hope you can now find and check out those lines of the relevant loop code which fill the buffer and then read back. 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 Datashee was only wanting to get it specifically to use the AT45DBD chip.

Could you help me make this work? 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, it looks like you still may be in luck. License discussion of dataflash.

Hello guys, I hope this thread is still alive so I will try to ask my question. There are numerous unresolved posts which would have been easily answered and 45eb161d by those generous individuals who give their time to assist others with their projects. Hi, thanks for the library! However, one thing you will need to change in the example sketch is the number of bytes written to the buffer datahseet match your memory size.

Do you know what I should change to eatasheet it work? In the example sketch I changed the page size to and removed the buffer 2 sections. I suggest you copy the ccp source block of code for a similar function to your new one. However, like many other things in that originally Atmel library, it is flakey. I wouldn’t expect this library to work with it.

Since this is dataeheet only code in the public domain which will allow arduino to use atmel dataflash with full functionality, I have added a splash line at the top of the cpp and dataflash. To moderator – the current dataflash library in the arduino playground does not work properly. I have done nothing more than go through the files line by line checking what the actual code does.

45vb161d I checked the Opcodes for: I find Keywords are very useful, because spelling mistakes get spotted by their ‘plain’ text colour. I have re-written the playground dataflash library so it works.

The old version needs replacing with this one, 45fb161d 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.

I have fixed those parts and now it does. There are a few op-codes not yet implemented, eg block erase, which is very quick.

Should this library work with this chip? These parts with the F suffix are in full production 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? I included my sketch below and the serial output. Only change the relevant op-codethen create a new function name and create a prototype in dataflash.
