Its a few years late, but over the winter i finally got it done.

I've tried to put everything on one page, that way you don't have to flip through pages to see all the parameters.
There is an Exerciser in every viper with V3.0 and greater. It will rock back and forth automatically so you can display the position and error waveforms.



Using vipertune, i've found a few things in the drive that i will fix. With it i've been able to really see what effect parameters like balance and hysterysis can do. You can tune much tighter using Viper tune than manually entering parameters !

You can also save / load parameters to file. (.vip)

I have more to add to Viper Tune, but i couldn't hold people up any more. Let me know your feed back and bugs.

BTW, screen design and colors are not my strong point. I wasted a lot of time agonizing over the colors and background !
I know, I'm graphically challenged !
