Okay,
I already talked to Alan :)
Bottom line is, he's not sure. We are confident that we can handle the code needed to make it work on our end, but what we don't know is how a hacked servo truly behaves. People usually hack servos in order to make robots. They attach the servo to the wheels and use them to drive around. What we are afraid of is that a hacked servo won't understand what you mean when you try to tell it to go to 280 etc. It might try to spin forever.
So we will play with it on our end. Alan says he needs the same thing and as you said, many people do. So I'd love to figure something out.
I will post what we discover here in this forum. Alan is a very busy cat these days so we are probably talking a month timeline or something like it.
Thanks!
Matt
