此設(shè)計(jì)包括了直流步進(jìn)機(jī)的源程序代碼，可以直接使用，
是用KEIL軟件編的程序
程序如下：
#include<AT89X52.h>
#include<intrins.h>
#include<main.h>
bit moto_dir=0;
uchar irq_count ;
uchar irq_count_t;
uchar PWM_TIME_H;
uchar PWM_TIME_L;
bit i=0;
void shortdelay()
{
unsigned char k,j;
for(k=0;k>20;k--)
  for(j=248;j>0;j--);
}
void run()
{
   if(FZ_KEY)
   { shortdelay();
   if(FZ_KEY)
   { moto_dir=1;
PWM3=0;PWM4=1;
   }

   while(FZ_KEY);
   }
   if(ZZ_KEY)
   {
      shortdelay();
   if(ZZ_KEY)
   {
   moto_dir=0;
PWM3=1;PWM4=0; }
      while(ZZ_KEY);
}

   if(UP_KEY)
   { shortdelay();
   if(UP_KEY)
   {
   if(PWM_TIME_H>10)
   {
   PWM_TIME_H--;
   PWM_TIME_L=100-PWM_TIME_H;
   }
   }
   while(UP_KEY);
   }
   if(DOWN_KEY)
   { shortdelay();
   if(DOWN_KEY){
      if(PWM_TIME_H<90)
   {
   PWM_TIME_H++;
   PWM_TIME_L=100-PWM_TIME_H;
   }
   }
   while(DOWN_KEY);
   }
   }
void main()
{ PWM1=1;PWM2=1;PWM3=1;PWM4=1;
irq_count=0;
i=0;
PWM_TIME_H=80;
PWM_TIME_L=20;
ET1=1;
TMOD=0X11;
TH1=0XFC;
TL1=0X18;
TR1=1;
EA=1;
while(1)
run();
}
   void timer1() interrupt 3 using 1
   {
   TH1=0XFC;
   TL1=0X18;
   irq_count++;
   if(irq_count>=irq_count_t)
   {
   irq_count=0;
   i=~i;
   if(i==1)
   irq_count_t= PWM_TIME_H;
   else
   irq_count_t=PWM_TIME_L;
   if( moto_dir==1)
   {PWM2=~PWM2;PWM1=1;}
   else
   {PWM2=1;PWM1=~PWM1;}
   }
   }
