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

Archiver

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/serialport/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
