Hello,
Does anyone have any experience or code with interfacing to the iButton
from Dallas Semiconductors? Specifically, I want to hook the Blue Dot
receptor up to the Basic Stamp so I can read info from an iButton.
Thanks,
Heath

    I'm going to be working with this over the summer. I'm not really sure about
    the I/O properties of the blue dot. I'm also not real sure how the stamp
    would communicate. The communications that I've done is using a Java program
    programmed with their free development software. I don't know if there is a
    way besides having the host Java program request the info, to get the info
    off the iButton.

    Heath I went wild over the iButton a year or so ago. In short, I had some
    radio equip stolen and even though I could positively recognize one in a
    pawn shop I couldn't prove it was mine. I bought a sample of every button
    Dsemi made and had a ball playing with them. Of course I got their kit with
    software, probe and all. Their 3 legged transistor looking buttons can be
    conceiled in any electronic device and used prove ownership. I wrote a
    little basic program to use in an old lap top so I could do the
    identification right at the pawn shop counter if necessary. But to your
    question. I've seen may responses in the past by folks answering simular
    questions. Most say the stamp isn't fast enough. Some claimed sucess but I
    could never understand their programming. I'm sure my fault not theirs. Via
    searches I located portable devices to read the button but the expense was
    way out of line for my purpose. If you come up with something simple I'd
    sure like to know...... ==Mac== AG5F

    Hi

    I have a DS1996 ibutton and a basic stamp module (BS2).I would like
    to transfer data between the two components.
    Without using a BS2p stamp is this possible?. I have found a few
    lines of code at http://home.earthlink.net/~parkiss/demos.html can
    anyone confirm that this code works.

    Best regards

    You'll need a protocol-converter between the BS2 and your iButton. The
    code you point to on Steve's site uses his 1-Wire converter (programmed
    SX chip).
