ARM液晶显示界面频率设置截面，用于对信号输出频率进行设置-ARM LCD interface section of the frequency settings for the output frequency of the signal set

提供的程序是供四相步进电机使用。本实验使用的步进电机用直流+12V电压，电机线圈由A、B、C、D四相组成。 2. 驱动方式为四相单四拍方式,各线圈通电顺序如下表。表中首先向A相线圈输入驱动电流，接着向B，C，D线圈通电，最后又返回到A相线圈驱动，按这种顺序轮流切换，电机轴按顺时针方向旋转。若通电顺序相反，则电机轴按逆时针方向旋转。-provide for the procedures of the four-phase stepper motor use. This experiment used the stepper motor 12V DC voltage electrical coils A, B, C, D phase. 2. Four-driven approach to making four single-phase, the coil electrifying sequence the following table. Table A first phase coil input drive current, then to B, C, D coil electricity and eventually return to the A-phase coil driven by the rotation order of this switch, the electrical axis by rotating clockwise direction. If electricity in reverse order, the motor shaft by the anti-clockwise rotation.
