High-level thought is to add a small resistor to the ground side, buffer=20 and measure that with a microcontroller and dynamically=20 increase/decrease the motor output signal from the microcontroller to=20 get a specific current. Is it as simple as this? Cheers, -Neil. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
