Am I on a right way? I hope you can now find and check out those lines datsaheet the relevant loop code which fill the buffer and then read back. I tried the example, but it is not working. FYI I checked the Opcodes for: However, it looks like you still may be in luck.

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. To moderator – the current dataflash library in the arduino playground does not work properly.

Thank you for your time and effort. There are a few dattasheet not yet implemented, eg block erase, which is very quick. Only change the relevant op-codethen create a new function name and create a prototype in dataflash. I have fixed those parts and now it does.

All it would now need is a reference to this updated version. Perhaps a moderator can substitute this updated Atmel dataflash library and example on the Arduino Playground?

I was interrupted by an official at the frontdoor halfway through last posting and forget to tidy up the example. 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 I was only wanting to get it specifically to use the AT45DBD chip. 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.

Do you know what I should change to make it work? Also the same change needed when reading back those test values.

These devices are dqtasheet 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.

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.

45d1b61d, 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. In the example sketch I changed the page size to and removed the buffer 2 sections.

Could you help me make this work? Interactive addressable led displays for holidays; interactive robots for fun. Hello guys, I hope this thread is still alive so I will try to ask my question. Dataflash is a specific type of flash that was made to work with Atmel chips.

However, like many other things in that originally Atmel library, it is flakey. Hi, thanks for the library! I included my sketch below and datasbeet serial output. License discussion of dataflash. I also know how to connect one single DataFlash memory with the Arduino: I find Keywords are very useful, because spelling mistakes get spotted by their ‘plain’ text colour.

The change to byte pages from default bytes is ‘once-only’. 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. Just a reminder if you choose to do that.
