Stepper motor with its composition as a result of the open-loop system is simple, cheap and very practical, so printers and other office automation equipment and various control devices, and many other fields have a very wide range of applications.
This article describes a microcontroller-based stepper motor system design, assembly language with the preparation of a motor is transferred, reverse, speed up, slow down, stop the procedure, through the microcontroller, motor driver chip and the corresponding ULN2004 The key to achieve the above functions, and stepper motor to use the work of the state of the light-emitting diode display. This article introduced the principle of stepper motor, as well as single-chip microcomputer, the system hardware circuit, the program components, while software and hardware for the debugging, the debugging process at the same time to introduce the problems and the solution to the problem. The clear design, high reliability, stability, etc., through the realization of the above-mentioned functional debugging.
