解决plc 与 labview 写的上位机通讯的 示范例子。

利用labview读取csv文件数据,到数组并显示(Read CSV file data to array and display)

基于LabVIEW的时域分析_自相关函数(autocorrelation function)

说明：  labview 振动分析软件,该软件可通过声卡采集信号(LabVIEW vibration analysis software that can be collected through the sound signal)

labview做的密码登录系统，简单好用(LabVIEW password login system, simple and easy to use)

I was suprised LabVIEW didn t had the CRC32. So I made it, http://en.wikipedia....edundancy_check, http://www.ietf.org/rfc/rfc1952.txt. It can take a array of U32, one element of U32 or a string. When needed I can create more CRC checks, CRC8, CRC16, etc... but CRC32 is the most used one I readed.

说明：  可以对单次输入的信号进行滤波分析和图像显示。同时也具备暂停和历史图像保存的功能。 本程序主要针对的是低频率的未知信号，对于高频率信号最好采用单次采样的方式。(The single input signal can be filtered and analyzed, and the image can be displayed. It also has the functions of pausing and preserving historical images. This program is mainly for low frequency unknown signals, for high frequency signals, the best way to use a single sampling.)

说明：  数据采集卡采集拉力值，与预先设定的拉力值进行比较，然后PID运算，控制相应的PWM占空比输出，最终控制电机的速度(The data acquisition card collects the pull value and compares it with the pre-set pull value. Then the PID arithmetic is used to control the output of the corresponding PWM duty cycle, and finally the speed of the motor is controlled.)
