sci.electronics.design stepper controllers: software examples, hardware examples
Can anyone suggest application notes or software source or circuit diagrams or texts about stepper motor controllers with means of sensing current through the coils & measuring the voltages there also and using that info to determine when the stepping pulse should occur? There exist lots of data about driving steppers according to predetermined and fixed actions, but very little about sensing steppers and driving them accordingly. Any info about the latter would be appreciated.
