考试序列号 18 课 程 设 计 论文题目：步进电机角度控制(2)课程名称：计算机控制技术 学 院 自动化学院 专业班级 学 号 8 姓 名 指导教师 2013 年 06 月 25 日一、 目的：1. 巩固和加深对计算机控制技术课程内容的认识和理解，提高应用水平。2. 熟悉键盘控制和七段数码管的使用。3. 掌握直流电机的速度控制和测试方法。二、 课程设计内容1. 在显示器上显示任意四位十进制数。2. 将8个键定义键值为07，按任意键在显示器上显示对应键值。3. 实现：（1） 定义键盘按键：5个数字键；3个功能键：设置SET、清零CLR、开始START；（2） 显示器上第一位显示次数，后三位显示每次行走的角度；（3） 通过键盘的按键，设置步进电机各次的角度值；按动SET键后，开始设置：第一位设置次数，后三位设置角度值，再按动SET置入；可连续置入的角度。（4） 按START键启动步进电机开始转动，到位后停止；按CLR键清零步进电机回原位。4. 电路框图（参见任务书）。三、 任务要求1. 设置键盘为下图所示：2457CLRSETSTART02. 要求实现以下功能：（1） 键入4（次数）270（角度值）键入SET设置完毕，键入START步进电机转动270度4次；停止后键入CLR返回零位；每个过程都必须有相关的显示。（2） 键入7（次数）45（角度值）键入SET设置完毕，键入START步进电机转动45度7次；停止后键入CLR返回零位；每个过程都必须有相关的显示。四、 程序代码实验一：按键设置为0178 EFAB程序：ORG0000HLJMP
