关于步进电机的单片机实现，实现转速等等的控制，正反转控制等等，利用电子电路，将直流电变成分时供电的，多相时序控制电流，用这种电流为步进电机供电，步进电机才能正常工作，驱动器就是为步进电机分时供电的，多相时序控制器 -On-chip stepper motor, achieving speed control, etc., etc. Reversible control, acceleration and deceleration acceleration and deceleration acceleration and deceleration acceleration and deceleration acceleration and deceleration acceleration and deceleration acceleration and deceleration acceleration and deceleration acceleration and deceleration
