I've done something similar on a standard linux based PC using a sound
card, with frequencies convering the audio range[1] (or more accurately the
range of the audio card). But then that's what I needed and hence why I
wrote the software.
So...
What sort of frequencies do you need to generate?
What hardware were you thinking of using for your project?
How where you thinking of generating the square wave?
