C语言开定时器做呼吸灯程序 单片机制作呼吸灯的C语言程序怎么样编写

#include

sbit LED0=P0^0;

sbit wei=P1^1;

sbit duan=P1^0;

sbit lcden=P1^7;

sbit dianzhen=P1^3;

sbit leden=P1^2;

void Delay(unsigned int t);

void main (void)

{

unsigned int CYCLE=600,PWM_LOW=0;//定义周期并赋值

lcden=0;

P0=0x00;

dianzhen=0;

P0=0xff;

wei=0;

duan=0;

while (1) //主循环

{

LED0=1;

Delay(150000); //特意加延时，可以看到熄灭的过程

for(PWM_LOW=1;PWM_LOW

{

LED0=0;

Delay(PWM_LOW);

LED0=1;

Delay(CYCLE-PWM_LOW);

}

for(PWM_LOW=CYCLE-1;PWM_LOW>0;PWM_LOW--)

Delay(PWM_LOW);

LED0=1;

Delay(CYCLE-PWM_LOW);

}

}

}

void Delay(unsigned int t)
