Should this library work with this chip? Am I on a right way?
However when I print the read values they are apparently random numbers except for the first value. Interactive addressable led displays for holidays; interactive robots for fun. I have found obvious and unexplained bits of code which meant it would never have worked with Arduino.

I suggest you copy the ccp source block of code for a similar function to your new one. I have fixed those parts and now it does.
I was interrupted by an official at the frontdoor halfway through last posting and forget to tidy up the example. However, one thing you will need to change in the example sketch is the number of bytes datasehet to the buffer to match your memory size.
I tried the example, but it is not working. I find Keywords are very useful, because spelling mistakes get spotted by their ‘plain’ text colour. Dataflash vatasheet a specific type of flash that was made to work with Atmel chips.

All it would now need is a reference to this updated version. Someone has written a library for the Winbond flash you have here: FYI I checked the Opcodes for: However, like many dataxheet things in that originally Atmel library, it is flakey.
The old version needs replacing with this one, then problems with datashest 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. Also the same change needed when reading back those test values.
There are numerous unresolved datasjeet which would have been easily answered and fixed by those generous individuals who give their time to assist others with their projects. Could you help me make this work? I am not an expert. 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.
Thank you for your time and effort.

Well, I mean I probably would. I wouldn’t expect this library to work with it. To moderator – the current dataflash library in the arduino playground does not work properly.
However, it looks like you still may be in luck. License discussion of dataflash. I have re-written the playground dataflash library so it works.
I also know how to connect one single DataFlash memory with the Arduino: I have done nothing more than go through the files line by line checking what the actual code does.
I included my sketch below and the serial output.
Sorry I can’t give xatasheet 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. 45db161x the example sketch I changed the page size to and removed the buffer 2 sections. These devices are now almost vintage, you may have better luck on trying for help on one of the AVR forum. Just a reminder if you choose to do that.
The change to byte pages from default bytes is ‘once-only’. 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.
Do you know what I should change to make it work? Perhaps a moderator can substitute this updated Atmel dataflash library and example on the Arduino Playground? Since this is the 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 45vb161d dataflash.
