《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
/* 名称:闪烁的LED 说明:LED按设定的时间间隔闪烁 */
#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); } }
02 从左到右的流水灯
/* 名称:从左到右的流水灯 说明:接在P0口的8个LED从左到右循环依次点亮,产生走马灯效果 */
#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
#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 */
#include
#define uchar unsigned char #define uint unsigned int uchar code Pattern_P0[]= {
