变频器控制(485)

这个程序可以实现两个串口直接的通信，labview(This program can realize two serial communication directly)

实现了Labview中格式为TDMS的数据文件的读取，并能够在波形图表中显示数据文件中记录的波形。(Achieved in Labview TDMS data file format is read, and the ability to display data in the waveform chart waveform records in the file.)

labview 计算 CRC ，通过labview 计算CRC 校验(labview COUNT CRC 32BIT LABVIEW)

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：  labview中常常需要显示列表，并需要制作自动排序，表头，多选等功能。本Xcontrol集成了这些功能，这样就不用每次都去写麻烦的曲线操作了！(LabVIEW often needs to display the list, and need to make automatic sorting, header, multi selection and other functions. This XControl integrates these functions, so you don't have to write troublesome curve operations every time!)

通过设定扫频范围及采样信息，产生一个chrip 信号。(generate a chirp signal, this vi could be used as a signal generation for free.)

使用labview进行信号分析，主要用到了傅立叶变换和小波分析，私家珍藏，互联网上其他地方是找不到的(Labview signal analysis, the main use of the Fourier transform and wavelet analysis,)

一种基于labview的ASCII和Uniocode转换的程序。(A LabVIEW-based ASCII and Uniocode conversion program.)

使用EMD对采集数据进行数据模态分解，得到各个分量信号(Use EMD to cEMD data)

labview对信号fft变换及信噪比分析(Signal FFT transform and signal to noise ratio analysis of LabVIEW)
