基于L298N电机驱动模块的设计与实现(3)

Based on L298N motor driver module design and

implementation

Abstract

This design realized step motor, reverse days, speeding up the turn fast, slow, slow turn function, the whole system by writing to the single chip microcomputer program allocation good control of the word and the corresponding storage unit of the memory address assignment; Reboot your system, from single chip I/O mouth output control pulse, after L298N driving circuit pulse processing, the output can directly control the step motor pulse signal. On this basis, to redistribute the I/O resources, also can increase the number of L298N drive chip, load ability range within the allowed in, still can achieve more TaiBu into motor independent film, inversion, accelerate turn fast, slow, slow turn control.

Keywords: AT89C51 ; L298N ; Stepping motor
