Abstract:Based on the design of the stepper motor control MCU. AT89C51 is the core of the signal measurement and control systems 12,864 pairs of used motor LCD state-speed, SCM Timer pulse power distribution and stepper motor drive circuit comprising the flooding UNL2003 actuator, software to control the motor, shifted. LCD12864 as LCD interface, the keyboard combination with the motor running circles set the number of speed direction equivalent to enable the system from the PC under normal operation may also have good man-machine interaction. improve the usability of the system. The design using C language programming and modular design, enhance readability, a motor movement control functions.
