单片机C语言程序设计实训100例--基于8051+PROTEUS仿真1

《单片机C语言程序设计实训100例—基于8051+Proteus仿真》案例 第 01 篇 基础程序设计

01 闪烁的LED

LED 名称：闪烁的/*

按设定的时间间隔闪烁说明：LED */

#include #define uchar unsigned char #define uint unsigned int sbit LED=P1^0;

延时//void DelayMS(uint x) { uchar i; while(x--) {

for(i=0;i<120;i++); }

}

主程序//void main() { while(1) {

LED=~LED; DelayMS(150); } }

从左到右的流水灯02

名称：从左到右的流水灯/*

LED8个口的 说明：接在P0产生走从左到右循环依次点亮， 马灯效果*/ #include #include #define uchar unsigned char #define uint unsigned int 延时//

void DelayMS(uint x) { uchar i; while(x--) {

for(i=0;i<120;i++); } } //主程序 void main() {

P0=0xfe; while(1) {

P0=_crol_(P0,1); //P0的值向左循环移动 DelayMS(150); } }

03 8只LED左右来回点亮

/* 名称：8只LED左右来回点亮

说明：程序利用循环移位函数_crol_和_cror_形成来回滚动的效果 */

#include #include #define uchar unsigned char #define uint unsigned int //延时

void DelayMS(uint x) { uchar i; while(x--) {

for(i=0;i<120;i++); } } //主程序 void main() {

uchar i; P2=0x01; while(1) {

for(i=0;i<7;i++) {

P2=_crol_(P2,1); //P2的值向左循环移动 DelayMS(150); }

for(i=0;i<7;i++) {

P2=_cror_(P2,1); //P2的值向右循环移动 DelayMS(150); } } }

04 花样流水灯

/* 名称：花样流水灯

说明：16只LED分两组按预设的多种花样变换显示 */
