简易计数器，计数到了自动归零，重新触发重新开始，很有用-Simple counter, count to zero automatically re-trigger the re-start, very useful

通过数据采集模块计数器对输入光栅尺脉冲信号进行计数，脉冲与光栅尺移动距离一一对应，每个脉冲对应一个栅距，由脉冲数与栅距乘积得到光栅尺直线位移；计数函数采用与数据采集模块对应的usb2k1.dll库函数。-Through the data acquisition module counter input grating pulse signal count, pulse and grating moving distance correspondence, each pulse correspon

运行在labview实时环境下，RT端得FPGA码盘计数器的初始化程序，包括设定参数以及打开FPGA中的计数通道-Labview run in real-time environment, RT side have FPGA code disk counter initialization procedures, including setting parameters, and open the FPGA counting channel

倒计时计数，主要是具有程序暂停功能，暂停时计数器不动，点继续后，程序继续。这个功能在实际编程中很实用-Countdown counts, the main feature is a program pause, pause, the counter does not move, point to continue, the program continues. This feature is very useful in the actual programming
