    Default bs2-->rs232-->USB-->macintosh-->Java or C++

    I think that my problem is of the most basic nature--software to
    hardware-- but after searching for weeks for a definite answer, I am
    almost sure it is hopeless.

    Basically, I am trying to get numbers from a bs2 controlled sonar
    circuit into a variable in either java or c++ in my macintosh
    throught the usb port.

    I believe I have solved the USB part of this, but now I do not know
    how I will begin to go about getting the values into the software.

    Perhaps someone here has done some similar work on the mac and can
    help me a bit.

    Thanks

    Hi,

    This is a copy of an email I sent to someone else (or is it the same
    person??) :-)

    It relates to the FTDI USB chips/Modules...


    For the Mac, you install an Extension from ftdi which creates a "Virtual
    serial port".

    That means, that your existing programs that normally talk to the old Mac
    serial port will still believe they are talking to one, and the Extension
    will transfer any calls to the serial port to the FTDI chip instead.

    So, as far as writing software goes, you just carry one writing your
    programs, addressing the the serial port.

    I'm not sure about how to address a serial port in C++ for the Mac, but in
    RealBasic, it's something like:

    serial1.write "Hello!"

    As long as you have the extension installed, your program will work on a USB
    based Mac.

    Hope this helps,

    Cheers,

    Ben.

    Yes, I did send this to you personally as well. Sorry. I thought it would
    be good to put it on the board for all to see.
    Thanks again, and remember, the info you gave me is not on the internet at
    all!

    Hi,
    I don't know if this will help, I haven't used any of this, but from a
    distance it looks like you should check out:

    http://www.serialio.com/products/ser...serialport.htm

    They have mac versions, old and new. This stuff should work with any
    aftermarket usb-> serial adapter. The way to connect the stamp to a serial port
    is I think identical to how you would do it for the pc, you just need the
    pinouts...

    Good Luck, and please, if you make it work, post what you can here. I probably
    need to solve a similar problem myself soon.

    Stan

    Thanks Stan. I saw that page during my week-long struggle, but I kept
    searching for things that looked cheaper and finally settled on ftdi usb
    chips and drivers.
    Again thanks. I CAN'T BELIEVE i GET HELP WITH SUCH A SPECIFIC PROBLEM OOPS
    SOrry for the all caps.
