单片机C语言编写点亮两盏led灯 首先从中间两盏点亮 依次相邻两盏灯点亮 依次循环永不停息（单片机点亮八个led灯程序流程图）

#include

sbit M=P1^0;void delayms(unsigned char ms)

{

unsigned int i;

while(ms--)

{

for (i=0 ;i

}

}

main ()

{ unsigned char LED;

LED =0xff;

P1=LED;

while(1)

{ LED=0xe7;

P1=LED;

delayms(1000);

LED=0xdb;

P1=LED;

delayms(1000);

LED=0xbd;

P1=LED;

delayms(1000);

LED=0x7e;

P1=LED;

delayms(1000);

}
