这是基于89C51单片机的实用热水器监视器源程序，程序由汇编语言编写...

内容：1、本程序用于测试4相步进电机常规驱动 2、需要用跳帽或者杜邦线把信号输出端和对应的步进电机信号输入端连接起来 3、速度不可以调节的过快，不然就没有力矩转动了 4、按s4（设置成独立按键模式）可以控制正反转 -Contents: 1, the procedure used to test the four-phase stepper motor-driven two conventional, need to jump cap or the signal output line of DuPont and the corresponding stepper motor signal input terminal connected three speed adjustment can not be too fast, Otherwise, there would be no moment of rotation of the four, according to s4 (set to form an independent key mode) can control the positive inversion
