代码说明：

   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 (Content: This program is used to test the four-phase stepper motor conventional drive 2, you need to jump the caps or the DuPont line signal output and the corresponding stepper motor signal input to connect, the speed can not be adjusted too fast. otherwise there is no torque rotation, set individual keys by s4 () can control the reversing)
