Hi!
I am working on a sound card oscilloscope program.
The program should help secondary school students with electronic circuit (Chua's chaotic circuit) tutorials at home.
My sollution is to modify the NI Elvis' Oscilloscope program to interface with the PC's sound card.
The program is written in LabVIEW, and must be portable between Win32 and Linux platforms. I also have to implement the XY-Graph feature into the program.
I now succeded mounting off the code from the ELVIS hardware.
The main problem is with the DAQmx libraries.
Can I configure those libs in the program to get data from the sound card instead of the DAQ Card?
Or is there any DAQmx-compatible library that uses PC hardware?
Or what is the simplest sollution to modify that code to work on SoundCards?
This program should help a few hudred students to get familiar with science.
Please help!

I guess you want to use the soundcard, because of its low cost.
In that case you also might consider the cost of software,
and take a look at SciLab+SciCos or SciPy.
