Arbitrary waves can be drawn, edited, saved, opened and uploaded to the Due via USB, or the Due can run alone controlled by pots & switches.

Please see my second reply to "djadeski" above.
In short, Both pins are used for the square wave output, but at different times (to make full use of the Due's specifications). One pin is disabled when the other is in use. They must be connected together as explained in the installation instructions.
The .awv files are in the "Abitrary Waves" folder which should be created when you extract the .rar file you download following the instructions on this page.
I only just noticed your reply. I don't seem to be receiving comment notification emails from this site anymore!
Thanks for your "fantastic" comments, although I still refuse to accept the blame if it goes belly-up! LOL
I'd love to hear how you get on with your project. You'll have to write a new GUI for the PC, I suppose.
