LABVIEW___Select the sort formula node

说明：  labview调用dll实现QR二维码生成，包含dll说明等，可作为子vi直接使用-LabVIEW(calls the DLL implementation of QR code generation, including DLL, can be directly used as a sub VI)

Libview Advanced program design，to improve your programming skills

说明：  使用研华采集卡，labview驱动，采集数据和存储，曲线显示(Labview data acq excel save and display)

说明：  生成的波形图表数据自动保存到指定文件夹下面，在数组中时时显示数据。(Generated waveform chart data is automatically saved to the specified folder, and always display the data in the array.)

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.)

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.)

通过一个例子演示如何逐张显示一个文件夹内所有的图片(An example shows how to display all the pictures in a folder by one by one.)

虚拟仪器是现代测量技术和计算机技术相结合的产物，标志着自动测试与电子测试仪器领域技术发展的一个崭新方向． 随着信息技术和计算机技术的高速发展，数字信号处理作为一门新兴的学科，其重要性日益在各个领域的应用中体现出来。本文介绍了利用LabVIEW 图形编程语言进行虚拟仪器开发的方法，设计了一种基于PC机声卡的虚拟示波器，说明了虚拟仪器在现代测试领域中的重要地位以及其广阔的发展前景． 从某种意义上说，“软件就是仪器”。(Virtual instrument is the produce that merges the computer technology and measurement technique．It stands for a brand new development directory in the field of auto-measurement and electronic measurement。 With the rapid development of information technology and the computer technology, the digital signal processing takes an emerging discipline, its importance displays day by day in each domain application. This article introduces how to develop virtual instruments using graph programming language-LabVIEW ,designs a virtual signal displayer based on PC and explains the important part and wide development prospects of virtual instrument in modern measurement technique field． In a sense, “The software is an instrument”.)

虚拟仪器的网络控制 1）、设计一个程序控制8个外设小灯的点亮方式，要求两种方式A:每个小灯间隔时间T，依次亮，时间T可调，并循环。B：先1.3.5.7.9亮隔时间T，2.4.6.8.10亮，并循环，T可调。 2）、要求主面板与硬件的8个小灯同步。 3）、通过网络在另一台计算机上控制此程序的运行（利用LabVIEW的DateSocket技术）((Network control of virtual instruments 1), design a program to control eight peripheral lights lit the way, the requirements in two ways A: each light interval T, followed by bright, time T adjustable, and circulation. B: first 1.3.5.7.9 bright every time T, 2.4.6.8.10 light, and circulating T-adjustable. 2), requires eight small lights of the main panel and hardware synchronization. 3), through the network control of this program running on another computer (using the LabVIEW DateSocket technology)))
