I'm happy with the graph code that I converted from the original. So now I have the forms, the hardware driver, the graph, and rudimentary function module. The function module is what does all the work, but it relies on the other parts (which I now have).

I hope to release the code under GPL, but I need agreement from the original author. If not, it will still be released for free, but under a different license.

I'm taking a break now, so I'll work on it again when I get back.
