步进电机驱动程序,5线

1 设置，
8051 & ULN2003

2. 正反转控制
uchar phasecw[4] ={0x08,0x04,0x02,0x01};正转，电机导通顺序 D-C-B-A
uchar phaseccw[4]={0x01,0x02,0x04,0x08};//反转，电机导通顺序 A-B-C-D

3. 基本程序如下

  4. 加，减速度，改变延时时间
  void MotorCW(void)
  {
  uchar i;
  for(i=0;i<4;i++)
  {
  MotorData=phasecw[i];
  Delay_xms(4);//תËÙµ÷½Ú
  }
  }
