单片机实验及proteus仿真_C语言篇

单片机实验：说明，以下是我整理了一些在学习单片机的过程中所做的一些典型的实验，所有程序均用C 语言编写，为了方便，在仿真时电路能省的都被省掉了（比如省去晶振用了外部时钟）。

程序不一定很优化，也不一定完全没有错误，仅供大家参考。

希望大家一块学习！！！！第一：I/O操作篇实验一.闪烁的灯图:程序:#include "AT89X51.H"void delay02s();void main(void){while(1){P1_0=0; //P1.0=0 led点亮delay02s(); //延时0.2sP1_0=1; //P1.0=1 led熄灭delay02s(); //延时0.2s}}void delay02s(void) //延时0.2s的函数{unsigned char i,j,k;for(j=20;j>0;j--)for(i=20;i=0;i--)for(k=248;k=0;k--);}实验二:模拟开关程序:#include "AT89X51.H"void main(){while(1){if (P1_7==0) P1_0 = 0;//key按下P1_7=0,led点亮else if ( P1_7==1) P1_0 = 1;//key弹起P1_7=1,led熄灭}}实验三: 多路开关程序:#include "AT89X51.H"void main(){while(1){P1_0 = P1_7;P1_1 = P1_6;P1_2 = P1_5;P1_3 = P1_4;}}实验四:跑马灯(一)图:程序://单一灯的左移右移//八个发光二极管L1－L8分别接在单片机的P1.0－P1.7接口上//输出“0”时，发光二极管亮，开始时P1.0→P1.1→P1.2→P1.3→┅→P1.7→P1.6→┅→P1.0亮，重复循环。
