Buffer addressing is referenced in the datasheet using the terminology BFA9 – BFA0 to Read Timing” diagrams in this datasheet for details on the clock cycle . AT45DBD-SU Datasheet, 45DB 16M Flash Memory Datasheet, buy AT45DBD-SU. After power is applied and VCC is at the minimum specified datasheet value, the system should wait 20 ms before an opera- tional mode is started. Absolute.

However, it looks like you still may be in luck. I tried the example, but it is not working.

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? Dataflash is a specific type of flash that was made to work with Atmel chips.

License discussion of dataflash. Well, I mean I probably would.

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 ddatasheet allow arduino to use atmel dataflash with full functionality, I have added a splash line at the top of the cpp and dataflash.

I wouldn’t expect this library to work with it. Do you know what I should change to make it work? Firstly I must register my interest in Dataflash – Datashee work for Adesto, the company that has taken over from Atmel and is manufacturing the Dataflash parts now. These devices are now almost vintage, you may have better luck on trying for help on one of the AVR forum. I have 45db161 obvious and unexplained bits of code which meant it would never have worked with Arduino.


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

Hi, thanks for the library! To moderator – the current dataflash library in the arduino playground does not work properly. However, like many other things in that originally Atmel library, it is flakey. FYI I checked the Opcodes for: 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 also know how to connect one single DataFlash memory with the Arduino: There are a few op-codes not yet implemented, eg 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. 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.

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. 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. I am not an expert. Could you help me make this work? 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.

The change to byte pages from default bytes is ‘once-only’. I included my sketch below and the serial output. Dqtasheet 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 datashewt I was only wanting to get it specifically to use the AT45DBD chip.
