led流水灯
置顶的意思是这个没搞懂，再研究研究。
我也不知道啥叫流水灯。我做出来的是，D1亮一段时间，然后D1熄灭，D2亮一段时间。。。
是我没有看任何资料自己做出来的，挺有成就感的哈。

我这个好象不对哈，哈哈。
刚根据视频画了一个流水灯的示意图。
代码我再琢磨琢磨
其实改进也很简单，让D7到D2依次亮就可以了。
#include "reg52.h" #include "intrins.h" typedef unsigned char u8; typedef unsigned int u16; sbit ledD1=P2^0; sbit ledD2=P2^1; sbit ledD3=P2^2; sbit ledD4=P2^3; sbit ledD5=P2^4; sbit ledD6=P2^5; sbit ledD7=P2^6; sbit ledD8=P2^7; void delay(u16 i) //延时函数 { while(i--) { //什么也不做 }; } void main() { //D1到D8依次亮 while(1) { ledD1=0; delay(60000); ledD1=1; delay(60000); ledD2=0; delay(60000); ledD2=1; delay(60000); ledD3=0; delay(60000); ledD3=1; delay(60000); ledD4=0; delay(60000); ledD4=1; delay(60000); ledD5=0; delay(60000); ledD5=1; delay(60000); ledD6=0; delay(60000); ledD6=1; delay(60000); ledD7=0; delay(60000); ledD7=1; delay(60000); ledD8=0; delay(60000); ledD8=1; delay(60000); //以上的代码就是D1到D8依次亮 //D7到D2依次亮 ledD7=0; delay(60000); ledD7=1; delay(60000); ledD6=0; delay(60000); ledD6=1; delay(60000); ledD5=0; delay(60000); ledD5=1; delay(60000); ledD5=0; delay(60000); ledD5=1; delay(60000); ledD4=0; delay(60000); ledD4=1; delay(60000); ledD3=0; delay(60000); ledD3=1; delay(60000); ledD2=0; delay(60000); ledD2=1; delay(60000); } }
两个灯一起亮的流水灯
#include "reg52.h" #include "intrins.h" typedef unsigned char u8; typedef unsigned int u16; sbit ledD1=P2^0; sbit ledD2=P2^1; sbit ledD3=P2^2; sbit ledD4=P2^3; sbit ledD5=P2^4; sbit ledD6=P2^5; sbit ledD7=P2^6; sbit ledD8=P2^7; void delay(u16 i) //延时函数 { while(i--) { //什么也不做 }; } void main() { //D1到D8依次亮 while(1) { //D1 D2一起亮 ledD1=0; ledD2=0; delay(60000); ledD1=1; ledD2=1; delay(60000); //D3 D4一起亮 ledD3=0; ledD4=0; delay(60000); ledD3=1; ledD4=1; delay(60000); //D5 D6一起亮 ledD5=0; ledD6=0; delay(60000); ledD5=1; ledD6=1; delay(60000); //D7 D8一起亮 ledD7=0; ledD8=0; delay(60000); ledD7=1; ledD8=1; delay(60000); //D6 D5一起亮 ledD5=0; ledD6=0; delay(60000); ledD5=1; ledD6=1; delay(60000); //D4 D3 ledD3=0; ledD4=0; delay(60000); ledD3=1; ledD4=1; delay(60000); } }
给自己留了一个作业，当D1到D8的时候灯移动的速度越来越快，而从D8到D2的时候是灯移动越来越慢。
