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】。。。。实验内容【实验方案设计】实验电路编程实现:从VD1~VD32逐次点亮每个LED,然后熄灭。每个Led亮灯时间约为200ms。点亮VD32,200ms后再点亮VD31……最后点亮VD1,直到全部灯被点亮。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。重复上述过程。 【实验过程】程序如下:#include<>#defineLED_PORT0P0#defineLED_PORT1P1#defineLED_PORT2P2#defineLED_PORT3P3voidtime(unsignedintucMs);voidmain(void){ unsignedintucTimes; unsignedinttemp; #defineDELAY_TIME200 while(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LED for(ucTimes=0;ucTimes<8;ucTimes++){ LED_PORT0=LED_PORT0-(0x80>>ucTimes); time(DELAY_TIME); LED_PORT0=0xff; } for(ucTimes=0;ucTimes<8;ucTimes++){ LED_PORT1=LED_PORT1-(0x80>>ucTimes); time(DELAY_TIME); LED_PORT1=0xff; } for(ucTimes=0;ucTimes<8;ucTimes++){ LED_PORT2=LED_PORT2-(0x80>>ucTimes); time(DELAY_TIME); LED_PORT2=0xff; } for(ucTimes=0;ucTimes<8;ucTimes++){ LED_PORT3=LED_PORT3-(0x80>>ucTimes); 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;ucTimes<8;ucTimes++){ temp=temp-(0x01<<ucTimes); LED_PORT3=temp; time(DELAY_TIME); } temp=0xff; for(ucTimes=0;ucTimes<8;ucTimes++){ temp=temp-(0x01<<ucTimes); LED_PORT2=temp; time(DELAY
