there's no error for the amp to work with, only the commanded voltage which is now the tacho out. in op-am terms, you took the whatdoyouhave and plugged it into the whatdoyouwant eliminating all error so its kind of a catch 22, i'd say you get nothing out if you start with no velocity and keep the velocity if it wasnt 0 ( hard to do , you have to be infinitely quick with the jumpers) my2c tomp if you know the HitchikersGuide, this is what they did to the robot 'colin' ------------------------------------------------------------------------------ Own the Future-Intel® Level Up Game Demo Contest 2013 Rise to greatness in Intel's independent game demo contest.
