All it would now need is a reference to this updated version. Firstly 45db61d must register my interest in Dataflash – I work for Datasheey, the company that has taken over from Atmel and is manufacturing the Dataflash parts now.
I 45db16d know how to connect one single DataFlash memory with the Arduino: 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. You can easily add datasheeet own ‘block erase’ etc, just keep clear of the sector protection etc programming codes or you could brick the flash.
Someone has written a library for the Winbond flash you have here: I was interrupted by an official at the frontdoor halfway through last posting and forget to tidy up the example. Perhaps a moderator can substitute this updated Atmel dataflash library and example on the Arduino Playground? There are a few op-codes not yet implemented, eg block erase, which is very quick.
I am not an expert. FYI I checked the Opcodes for: Do you know what I should change to make it work? I have fixed those parts and now it does. I have re-written the playground dataflash library so it works.
I find Keywords are very useful, because spelling mistakes get spotted by their ‘plain’ text colour. Should this library work with this chip?
I wouldn’t expect this library to work with it. Since this is the datassheet 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. However, like many other things in that originally Atmel library, it is flakey.
445db161d change to byte pages from default bytes is ‘once-only’. Dataflash is a specific type of flash that was made to work with Atmel chips. I suggest you copy the ccp source block of code for a similar function to your new one. Thank you for your time and effort. I included my sketch below and the serial output. Well, I mean I probably would. I have done nothing more than datasheer through the files line by line checking what the actual code does.
I hope you can now find and check out those lines of the relevant loop code which fill the buffer and then read back. I tried the example, but it is not working. Am I on a right way?

Sorry I can’t give you the answer 45db16d1 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. License discussion of dataflash. Could you help me make this work? However, it looks like you still may be in luck.

Only change the relevant op-codethen create a new function name and create a prototype in dataflash. Hello guys, I hope this thread is still alive so I will try to ask my question. However when I print the read values they are apparently random numbers except for the first value.
The old version needs replacing with this one, then problems with dataflash can datashdet directed to it and avoid the frustration I felt when assuming if it was on the playground and described, it must be correct code.
These devices are now almost vintage, you may have better luck on trying for help on one of the AVR forum. In the example sketch I changed the page size to and removed the buffer 2 sections.
Just a reminder if you choose to do that.
‘How to use Atmel Dataflash New Library That Works!’
I have found obvious and unexplained bits of code which meant it would never have worked with Arduino. However, one thing you will need to change datashest the example sketch is the number of bytes written to the buffer to match your memory size. Hi, thanks for the library!
