Thank you for your time and effort. I included my sketch below and the serial output. FYI I checked datasheeet Opcodes for: I have re-written the playground dataflash library so it works. The change to byte pages from default bytes is ‘once-only’. The 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.

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 to match your memory size. I wouldn’t expect this library to work with it. Well, I mean I probably would.

License discussion of dataflash. Should this library work with this chip? I suggest you 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. I tried the example, but it is not working. 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 dztasheet D parts to the F parts in our FAQ section.

These devices are now almost vintage, you may have better luck on trying for help on one of the AVR forum. Someone has written a library for the Winbond flash you have here: However when I print the read values they are apparently random numbers except for the first value.

I have done nothing more than go through the files line by line checking what the actual code does. Also the same change needed when reading back those test values.

All it would now need is a reference to this updated version.

Just a reminder if you choose to do that. I 45d161d found obvious and unexplained bits of code which meant it would never have worked with Arduino. 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.

In the example sketch I changed the dwtasheet size to and removed the buffer 2 sections. Dataflash is a specific type of flash that was made to work with Atmel chips.

Interactive addressable led displays for holidays; interactive robots for fun. I was interrupted by an official at the frontdoor halfway through last posting and forget to tidy up the example. However, like many other things in that originally Atmel library, it is flakey. Am I on a right way?

I find Keywords are very useful, because spelling mistakes get spotted by their ‘plain’ text colour. Perhaps a moderator can substitute this updated Atmel dataflash library and example on the Arduino Playground?

I have fixed those parts and now it does. Firstly I must register my interest in Dataflash – I work dwtasheet Adesto, the company that has taken over from Atmel and is manufacturing the Dataflash parts now.

Do you know what I should change to make it work? I 45db1661d 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.
