用L298作为驱动器，控制两相混合式步进电机。 按键从上至下分别为减速，加速，正转，反转，停止。 具体参数还没有设定过。速度有些慢，加速按2下有效，然后就不能再快了。 转速输出是按照最小系统版的数码管写的。电路图里太麻烦就没画了。-Using L298 as the drive to control two-phase hybrid stepping motor. Buttons from top to bottom respectively, deceleration, acceleration, are being transferred, reverse, stop. Specific parameters have not yet been set. Some of the slow speed, speed up by 2, effectively, and then can not be faster. Speed output is in accordance with the minimum system version of the digital tube wrote. Circuit where not too much trouble drew.
