| 摘 要： | 本设计采用AT89C51对步进电机进行控制，通过单片机I／O口输出的方波作为步进电机的控制信号，信号经过L298N驱动电路来驱动步进电机，完成相应的规定动作：同时用键盘来控制任意坐标点的参数，并用LCD液晶显示器显示悬挂物体中画笔所在位置的坐标：软件功能模块主要完成对步进电机运动的位置、速度、方向以及运动时间的控制。

| Abstract: | The design takes advantage of MCU AT89C51 to control step-motor, the time-sequence square wave, output of I/O terminal of MCU acts as controlling signal of step-motor. It drives step-motor through L298N driving-circuit, and accomplishes corresponding given operation. Meanwhile, It uses keyboard to control the parameter of arbitrariness coordinate, and dialing-switch to select the operation which must be finished by step-motor. CRT is used to note the coordinate of the position of painting-pencil in the suspending object. Software function building block mairdy accomplishes controlling of the position, velocity, direction and time of the motion. |
