pulse counter实现脉冲计数，对非周期脉冲信号进行计数统计-pulse counter

实现测量脉冲信号的周期，脉冲持续时间，占空比等功能，进而通过脉冲周期获得电机转速的测量，以实现实时监控电机转速的目的。-Measure the pulse signal cycle, pulse duration, duty cycle, and other functions, and then measuring the rotational speed of motor through pulse cycle, in order to realize the purpose of real

本程序运行需要安装DAQ工具包，配合AD功能的采集卡采集脉冲波形后，实时监测周期固定的脉冲丢失数量。(This program needs to install the DAQ toolkit and collect the pulse waveform with the collection card of the AD function, and the quantity of the fixed pulse loss is fixed in real time.)
