labview中usb raw设备的读取和写入程序 非常有用(labview usb raw device in the read and write process is very useful)

基于Labview环境编程的随机数求和界面显示，内容包含前台和后台等的建立(Based on the Labview environment programming of random number and interface display, the content includes the front and back and so on)

用LabVIEW编制一个完整应用软件，完成以下功能： 1、产生一个正弦波，叠加一个噪声信号，从界面上可以调整噪声和信号的幅度、频率等参数，此信号作为后续分析的信号源； 2、显示信号的时域波形，点击按钮可以显示信号的幅度谱、功率谱 3、图形上可以显示光标，具有峰值跟踪功能，同时将峰值频率、幅度显示在界面上。 4、点击按钮可以计算显示信号的失真度（THD）、信噪比（SNR）、各次谐波的频率和幅度；(Preparation of a complete application using LabVIEW software, perform the following functions: 1, generates a sine wave, the superposition of a noise signal, the interface can be adjusted from the noise and the signal amplitude, frequency and other parameters, this signal as a follow-up analysis of the signal source 2. time-domain signal waveform display, click the button to display the signal amplitude spectrum, power spectrum 3, you can display a cursor on the graph, with a peak tracking, while the peak frequency, amplitude displayed on the screen. 4, click the button to display the calculated distortion (THD) signal to noise ratio (SNR), each harmonic frequency and amplitude )

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XY图点数实时显示，可自由改变显示的点数(The real-time display of XY diagram points can be realized, and the number of display points can be changed freely.)

NI公司的各种版本的labview,daq，09到17年，打开网址找到你需要的版本，下载安装包(Various versions of labview, DAQ)

优点：1，PPI协议通讯速度快，比OPC ，PCAccess，Modbus 快4-5倍左右。(就这一条优点就足了，呵呵) 2，PLC端无需编写任何通讯程序。 3，可以直接对PLC进行，RUN STOP等操作。 4，本程序全部采用LABVIEW底层程序框图，没用调用任何的DLL ，API等。这点对你学习还是修改程序功能都很有帮助，方便。 (Advantages: 1, PPI protocol communications faster than OPC, PCAccess, Modbus about 4-5 times faster. (On which an advantage on the feet, huh, huh) 2, PLC-side without writing any communication program. 3, can be carried out directly on the PLC, RUN STOP operation. 4, the procedure used in all LABVIEW underlying the block diagram, useless to call any DLL, API, etc. This is for you to learn or modify the program features are very helpful and convenient.)

说明：  labview学习资料，花了2W获得的过程学习资料，可以看看很多小例程，值得学习！(LabVIEW learning materials, spent 2W to get the process of learning materials, you can see a lot of small routines, worth learning!)
