用單片機控制，使壹個小燈（如P1.0）閃爍3次自動停止的程序怎麽寫？ 我初學

sbit LED P1.0;

#define LEDON LED = 0;//註意LED接法，這裏是單片機接LED負極

#define LEDOFF LED = 1;//

void delay_ms(unsigned int ms)

{

uchar i;

while(ms -- )

for(i = 0; i < 120 ; i ++);//晶振12M

}

void main(void)

{

LEDON;

delay_ms(1000);//1S

LEDOFF;

delay_ms(1000);//1S

LEDON;

delay_ms(1000);//1S

LEDOFF;

delay_ms(1000);//1S

LEDON;

delay_ms(1000);//1S

LEDOFF

while(1);

}
