控制步进电机正转，如：p3.2正转,p3.3反转,p3.4停止 步进电机接p1.0p1.1p1.2p1.3，正转，反转各3圈，正反快慢功能，是步进机的经典程序。-Stepper motor control is transferred, such as: p3.2 is transferred, p3.3 inversion, p3.4 stop stepper motor then p1.0p1.1p1.2p1.3, is turn, reversal of the 3 lap, both positive and negative speed function, is a classic step process machine.
