Many industry control devices request high precision of displacement and angle which is hard for common motors to realize, while the step motor may realize the angle and the rotation precisely.The design is about the control of stepping motor,which is based on the single-chip.Series control and parallel control are two modes of controlling step motors by single chip microcomputer. The design adopts serial control mode, in this case there are only two controlling lines between the single chip microcomputer system and the driver of the step motor .One is used to give out clock pulse to control the velocity, another is used to give out directional signal to control the direction. The two signals are all sent to the input of the driver of the step motor, which includes the ring dividing driver .Because of this, the system has a very simple structure.
