《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 *

#include

02 从左到右的流水灯

* 名称：从左到右的流水灯 *

#include

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 while(1) { }

LED=~LED; DelayMS(150);

说明：LED按设定的时间间隔闪烁

}

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 *

#include

uchar i; P2=0x01;延时 while(1) {

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

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

P2=_cror_(P2,1); P2的值向右循环移动 P2=_crol_(P2,1); P2的值向左循环移动 DelayMS(150);

说明：程序利用循环移位函数_crol_和_cror_形成来回滚动的效果

}

}

}

DelayMS(150);

04 花样流水灯 * 名称：花样流水灯 *
