    Hiya,

    I'm currently interested in finding some information and source code
    about implementmenting storage on a secure digital card (could be
    compactflash or smartmedia also) ideally it would implement fat16

    i've searched many times on google, found bits and pieces but nothing
    that is really "walk-through" which is what I want.

    Cheers

    Dave

    I was on the sansdisk site yesterday (different PC, so no url, sorry).
    They have docs on 8051 +ide+SD stuff

    Unfortunately the sdcard.org people release the real documentation
    under NDA and charge $$$$ for it. There is a small document on their
    webpage, but it is not enough to implement the card. I considered
    using SD on my last board, but chose not to due to lack of docs.

    Compact Flash has free documentation, but the interface consists of
    more pins (memory mapped mode would be easiest with a microcontroller).
