LABVIEW与PLC的OPC通讯

该文件是labview实现例子，写入和读取二进制文件。(This file is an example of LabVIEW implementation, writing and reading binary files.)

labview写的modus CRC 校验Vi。 输入发送内容自动计算出CRC校验码。

基于labview的FIR数字滤波器课程设计文档，附vi程序(FIR digital filter based on LabVIEW curriculum design document, attached to the VI program)

采用虚拟仪器LabWindows/CVI软件平台开发了基于PCI-6221多功能数据采集卡的实时频谱分析仪。(Virtual instrument LabWindows/CVI software platform based on real-time spectrum PCI-6221 multifunction data acquisition card analyzer.)

使用LabVIEW实现了DDS芯片AD9833的编程助手的功能，输入晶振频率和想要的输出频率即可得到控制字。很方便编程。(Using LabVIEW to implement the function of the DDS chip AD9833 s programming assistant, you can get the control word by typing the oscillator frequency and the desired output frequency. It s easy to program. )

方根幅值是计算裕度指标与波性指标的必要部分，本文件将其独立做成了一个子VI，方便labview程序调用。希望对小伙伴有所帮助！(The root mean square amplitude is a necessary part of the margin index and the wave index. This document makes it a sub VI, which is convenient for LabVIEW program call. Hope to help small partners!)

说明：  介绍了Labview编程中的堆栈技术，提供demo案例。(This paper introduces the stack technology in Labview programming and provides demo cases.)

labview制作系统登录界面 包含数据库，拥有用户管理等功能，可直接用于工程项目。(labview production system login interface contains a , with user management functions, it can be directly used for engineering projects.)
