快速FFT变换

此程序是基于labview的tcp/ip控件设计的多功能聊天软件，类QQ，可以进行文本、图片、文件等传输，可以在局域网、广域网内进行传输，具有很好的适用性，可以进行课程设计或毕业设计(This procedure is based on the labview tcp/ip control design versatility chat software, classes QQ, can be text, images, documents, etc. transfer, can be transmitted within a LAN, WAN, with good applicability and can be curriculum design or graduation)

实现多通道的应变采集，包括自动清0，手动清0等(Multi-channel strain collection, including cleared automatically, manually cleared, etc.)

说明：  视觉图像处理图片二值化基于labview，简单易懂谢谢参考(Visual image processing image binarization based on LabVIEW, easy to understand, thank you for your reference)

通过labview 对信号进行分析，主要包括基于FFT求信号功率谱(The signal is analyzed by LabVIEW, mainly including the signal power spectrum based on FFT)

labwindows/CVI 串口上位机源代码(LabWindows/CVI Serial)

分享下labview图形显示控件，非常好用的呀(Share the labview graphical display control, very easy to use, suitable for LabVIEW beginners)

并在Labview上实现了滑模控制器，利用roboRIO可实现对2自由度脚踝康复机器人的实时控制。(The sliding mode controller is implemented on Labview, and the real-time control of the 2 degree of freedom ankle rehabilitation robot can be realized by using roboRIO.)

Labview调用dll文件，实现加、减、乘、除等运算，可以用来学习labview调用dll的方法。(Labview call dll file, add, subtract, multiply, divide, such as computing, the method can be used to learn labview call dll' s.)

基于labview的虚拟波形发生器，能够实现正弦、余弦、锯齿波的产生(Labview-based virtual waveform generator, to achieve the sine, cosine, sawtooth generation)

说明：  阈值分割的各种方法的集合。局部阈值分割法，全局手动、自动阈值分割(A set of thresholding methods. Local Threshold Segmentation, Global Manual and Automatic Threshold Segmentation)
