这也是流水灯好吧，递增点亮，
#include "reg51.h"
#define uint unsigned int
#define uchar unsigned char
const table[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f, //正向流水灯
0xbf,0xdf,0xef,0xf7,0xfb,0xfd,0xfe,0xff, //反向流水灯
0xaa,0x55,0xaa,0x55,0xaa,0x55,0xff, //隔灯闪烁
0xf0,0x0f,0xf0,0x0f,0xff, //高四盏闪烁，低四盏闪烁
0x33,0xcc,0x33,0xcc,0x33,0xcc,0xff}; //隔两盏闪烁
void delay(uint z) //delay 1ms
{
uint x,y;
for(x=z;x>0;x--)
for(y=124;y>0;y--);
}
void main(void)
{
uchar x;
while(1)
{
for(x=0;x<35;x++)
{
P2=table[x];
P1=table[x];
P0=table[x];
delay(1000);
}
}
}
你算下，把数组改下就行了，很简单。
