    A few quick question about the flash memory on the dragonfly.
    I have used the sample code to store data in the flash memory.

    Where is the data actually stored? I see from the code that is uses an SPI port.
    How much memory is available?

    Thanks,
    Will.

    Will,

    Are you referring to the Dragonfly Filesystem Example program?

    https://developer.mbed.org/teams/MultiTech/code/Dragonfly_Filesystem_Example/

    The Dragonfly has a 2MB external flash connected via SPI.

    Cheers,

    Mike

    Hi Mike,
    Yes that is the sample code I was referring to. I used the link button to embed the link in my original post but it did not show up in the actual post.

    That is the answer I was looking for.
    Thanks.

    Hi Mike,
    Could you provide the part number on the Flash IC. I’d like to look at the datasheet to see the current requirements. Our app runs off of a battery and I would to determine just how much more current the flash will use.

    Thanks,
    Will.
