1、基于51单片机的C语言程序设计实训100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#defineucharunsignedchar#defineuintunsignedintsbitLED=P1^0;//延时voidDelayMS(uintx){uchari;while(x--){for(i=0;i<120;i++);}}//主程序voidmain(){while(1){LED=~LED;DelayMS(150);}}0
2、2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#include#defineucharunsignedchar#defineuintunsignedint77//延时voidDelayMS(uintx){uchari;while(x--){for(i=0;i<120;i++);}}//主程序voidmain(){P0=0xfe;while(1){P0=_crol_(P0,1);//P0的
3、值向左循环移动DelayMS(150);}}038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#defineucharunsignedchar#defineuintunsignedint//延时voidDelayMS(uintx){uchari;while(x--){for(i=0;i<120;i++);}}//主程序voidmain(){uchari;P
