实现单片机控制步进电机正反转,能够在270°范围内实现正反转，只要改变程序中j的参数就可改变正反转范围。-Realize the single-chip microcomputer control stepping motor and reversing

ADXL362是一款超低功耗、3轴MEMS加速度计，输出数据 速率为100 Hz 时功耗低于2 μA ，在运动触发唤醒模式下功耗 为270 nA 。与使用周期采样来实现低功耗的加速度计不同， ADXL362没有通过欠采样混叠输入信号；它采用全数据速 率对传感器的整个带宽进行采样(The ADXL362 is an ultra-low power, 3 axis MEMS accelerometer with output data When the speed is 100 Hz, t
