基于DLL的虚拟仪器设计

Design of Virtual Instrument Base on DLL (Dynamic Link Library)

该文介绍了虚拟仪器的开发环境LabVIEW的特点,分析并实现了利用动态链接技术实现LabVIEW和C语言的接口技术。文中阐述了LabVIEW和C语言接口的方法,并给出了应用实例。通过在LabVIEW中引入了C语言的强大功能,从而提高了LabVIEW的数据处理能力,并极大地增强了LabVIEW与其他Windows应用程序之间的数据共享能力。实践证明,该方法高效、易行,是增强LabVIEW整体功能的一条很好的途径。

The article introduces the characteristic of LabVIEW, the development environment. In addition, it analyzes and realizes how to implement the interface technology between LabVIEW and C programming language by using the DLL (Dynamic Link Library) technology. Here, the article describes the way for using C programming language in LabVIEW, and shows the example. By importing the powerful function of C language into LabVIEW, it improves the data processing ability of LabVIEW, and enhances its data sharing ability between other Windows applications. The experiment proves that this technique is highly effective, wieldy, and is a good way to enhance the whole function of LabVIEW.
