微型计算机控制技术课程设计步进电机

1、课程设计课程名称微型计算机控制技术 题目名称 步进电机角度控制(2) 学生学院 一 _自动化_ 专业班级学 号学生姓名指导教师李传芳2013 年 06 月 28 H一、软件设计流程图如下图所示:二、心得与体会这次的课程设计主要针对键盘及可编程接口芯片8255A的编程，在上机调试过程中山于 自己的疏忽及算法的不完善导致了程序不能实现预期的功能，经过一遍乂一遍的检查和思考, 终于完成了这次课程设计的任务。虽然上机调试的经历是痛苦的，但是期间的细节错误给了我们应有的教训，使我们在以后的 学习及工作中尽量避免，对于汇编语言的编程也有了进一步的了解加深了对步进电机的理解 和使用技巧，设计中，需要对步进电

2、机进行角度控制，即需要对步进电机的角度进行计算分 析，以得到所需的步数。总之，这次课程设计锻炼了我解决问题的能力，激发了我的思考，相信通过这次课程设 计对我以后对微机的继续学习及以后的工作会有很大的帮助。360AB72F移显示:1.2源程序:;键盘扫描KEYABC:CALL TIMEMOV DX,0604H IN AL,DXAND AL,60HCMP AL,60H 0000JNZ KEYJMP STTKEY: MOV AL,0FEH PCO=OMOV DX,0604HOUT DX,ALMOV DX,0604HIN AL,DXTEST AL,20HJNZ KEY_FCALL KEYAJMPSTT
