华工单片机IO口流水灯实验1报告

华南理工大学XXX课程实验报告实验题目:__________单片机I/O口－－流水灯_______________班级:___09信安（5）__指导教师:________张齐_________实验概述【实验目的及要求】1.学习单片机各I/O口结构特点及相关寄存器的使用方法。2.掌握一个简单具体的单片机项目的开发流程。3.了解ProteusISIS软件及使用方法。4.熟悉ProteusISIS与μVision2IDE开发环境的互连调试。实验内容【实验方案设计】实验电路编程实现：1）从VD1～VD32逐次点亮每个LED，然后熄灭。每个Led亮灯时间约为200ms。2）点亮VD32，200ms后再点亮VD31……最后点亮VD1，直到全部灯被点亮。3）在全部灯亮的情况下，从VD1～VD32逐次熄灭LED，熄灭VD1，延时200ms；然后熄灭VD2，延时200ms……熄灭VD32，全部灯熄灭。4）重复上述过程。【实验过程】程序如下：#includeREG52.H#defineLED_PORT0P0#defineLED_PORT1P1#defineLED_PORT2P2#defineLED_PORT3P3voidtime(unsignedintucMs);voidmain(void){unsignedintucTimes;unsignedinttemp;#defineDELAY_TIME200while(1){LED_PORT0=0xff;LED_PORT1=0xff;LED_PORT2=0xff;LED_PORT3=0xff;time(DELAY_TIME);//从VD1～VD32逐次点亮每个LEDfor(ucTimes=0;ucTimes8;ucTimes++){LED_PORT0=LED_PORT0-(0x80ucTimes);time(DELAY_TIME);LED_PORT0=0xff;}for(ucTimes=0;ucTimes8;ucTimes++){LED_PORT1=LED_PORT1-(0x80ucTimes);time(DELAY_TIME);LED_PORT1=0xff;}for(ucTimes=0;ucTimes8;ucTimes++){LED_PORT2=LED_PORT2-(0x80ucTimes);time(DELAY_TIME);LED_PORT2=0xff;}for(ucTimes=0;ucTimes8;ucTimes++){LED_PORT3=LED_PORT3-(0x80ucTimes);time(DELAY_TIME);LED_PORT3=0xff;}//点亮VD32，200ms后再点亮VD31……最后点亮VD1，直到全部灯被点亮。temp=0xff;for(ucTimes=0;ucTimes8;ucTimes++){temp=temp-(0x01ucTimes);LED_PORT3=temp;time(DELAY_TIME);}temp=0xff;for(ucTimes=0;ucTimes8;ucTimes++){temp=temp-(0x01ucTimes);LED_PORT2=temp;time(DELAY_TIME);}temp=0xff;for(ucTimes=0;ucTimes8;ucTimes++){temp=temp-(0x01ucTimes);LED_PORT1=temp;time(DELAY_TIME);}temp=0xff;for(ucTimes=0;ucTimes8;ucTimes++){temp=temp-(0x01ucTimes);LED_PORT0=temp;time(DELAY_TIME);}//在全部灯亮的情况下，从VD1～VD32逐次熄灭LEDtemp=0x00;for(ucTimes=0;ucTimes8;ucTimes++){temp=temp+(0x80ucTimes);LED_PORT0=temp;time(DELAY_TIME);}temp=0x00;for(ucTimes=0;ucTimes8;ucTimes++){temp=temp+(0x80ucTimes);LED_PORT1=temp;time(DELAY_TIME);}temp=0x00;for(ucTimes=0;ucTimes8;ucTimes++){temp=temp+(0x80ucTimes);LED_PORT2=temp;time(DELAY_TIME);}temp=0x00;for(ucTimes=0;ucTimes8;ucTimes++){temp=temp+(0x80ucTimes);LED_PORT3=temp;time(DELAY_TIME);}}//重复上述过程}voidtime(unsignedintucMs){#defineDELAYTIMES239unsignedcharucCounter;while(ucMs!=0){for(ucCounter=0;ucCounterDELAYTIMES;ucCounter++){}ucMs--;}}调试步骤：1.从VD1～VD32逐次点亮每个LED，每点亮一个断点一次2.点亮VD32，200ms后再点亮VD31……最后点亮VD1，直到全部灯被点亮。，每点亮一个断点一次3.在全部灯亮的情况下，从VD1～VD32逐次熄灭LED，每熄灭一个断点一次指导教师评语及成绩评语：成绩：指导教师签名：批阅日期：
