【Abstract】 The paper introduces the stepper motor controller and the program design for dancing robot. It adopts 74373 as the latch unit, 74LS244 and ULN2003 as the current and voltage amplifier in the circuit. The program design is based on bus time sharing and interrupt servicing. It can renew the speeds and the directions of every motor at real time.更多还原
