45db datasheet & applicatoin notes – Datasheet Archive

Interactive addressable led displays for holidays; interactive robots for fun. I have re-written the playground dataflash library so it works. 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.

Sorry I can’t give 4d5b161d 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. Just a reminder if you choose to do that. These devices are now almost vintage, you may have better luck on trying for help on one of the AVR forum. There are a few op-codes not yet implemented, 45db161 block erase, which is very quick. 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.


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

Do you know what I should change to make it work? I wouldn’t expect this library to work with it. I was interrupted by an official at the frontdoor halfway through last posting and forget to tidy up the example. 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 and dataflash. I have done nothing more than go through the files line by line checking what the actual code does.

‘How to use Atmel Dataflash New Library That Works!’

However, like many other things in that originally Atmel library, it is flakey. To moderator – the current dataflash library in the arduino playground does not work properly. I am not an expert. Dataflash is a specific type dagasheet flash that was made to work with Atmel chips. I hope you can now find and check out those lines of the relevant loop code which fill the buffer and then read back.

Perhaps a moderator can substitute this updated Atmel dataflash library and example on the Arduino Playground? License discussion of dataflash. Hello guys, I hope this thread is still alive so I will try to ask my question.

Well, I mean I probably would.

These parts with the F suffix are in full production are available in densities from 2Mbit to 64Mbit and have an applications 45d161d to help you move from the D parts to the F parts in our FAQ section. I also know how to connect one single DataFlash memory with the Arduino: 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.


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.

Thank you for your time and effort. Someone has written a library for the Winbond flash you have here: Also the same change needed when reading back those test values. Hi, thanks for the library! I have found obvious and unexplained bits of code which meant it would never have worked with Arduino. The change to byte pages from default bytes is ‘once-only’. Only change the relevant op-codethen create a new function name and create a prototype in dataflash.

Firstly I must register my interest in Dataflash – I work 45db11d Adesto, the company that has taken over from Atmel and is satasheet the Dataflash parts now. I find Keywords are very useful, because spelling mistakes get spotted by their ‘plain’ text colour. Am I on a right way?

Should this library work with this chip? In the example sketch I changed the page size to and removed the buffer 2 sections. I included my sketch below and the serial output.

I tried the example, but it is not working. However when I print the read values they are apparently random numbers daasheet for the first value.
