标题: MCI8051单片机控制步进电机


单片机源程序如下:

  2. unsigned char code FFW[]={0x01,0x03,0x02,0x06,0x04,0x0c,0x08,0x09};

  7. void DelayMS(unsigned char ms)
  8. {
  9.   unsigned char i;
  10. while(ms--)
  11. {
  12.    for(i=0;i<120;i++);
  13. }
  14. }
  15. void moter_FFW(unsigned char n)
  16. {
  17.   unsigned char i,j;
  18. for(i=0;i<5*n;i++)
  19. {
  20.    for(j=0;j<8;j++)
  21.   {
  22.     if(K3 == 0) break;
  23.    P1 = FFW[j];
  24.    DelayMS(25);
  25.   }
  26. }
  27. }
  28. void moter_REV(unsigned char n)
  29. {

  38.   }
  39. }
  40. }
  41. void main()
  42. {
  43.   unsigned char x = 3;
