摘要
LabVIEW是一个高效的图形化程序设计环境,在测量、测试及工业控制领域已有广泛的应用,但所用数据采集卡必须有NI(National Instruments)公司提供的驱动程序,大大限制了用户的选择。分析LabVIEW调用外部程序代码的途径,采用调动态链接库的方法编写LabVIEW环境下国产数据采集卡的驱动程序。实验证明,效果良好,满足测试要求,利用动态链接库调用外部程序代码是增强Lab-VIEW整体性能的一条有效途径。
Virtual Instrument development platform LabVIEW is a high efficiency graphical platform with extensive application in measuring, testing and industries control realm. But the DAQ (Data Acquisition) card needs the company of NI(National Instruments) to provide drive, which greatly limits the choice of the customers . Calling external code method in LabVIEW is discussed, and DLL (Dynamio Link Library) drive for the domestic data acquisition card is developed. It has been proved that the method is efficient, practicable, and is a good way to improve the overall performance of LabVIEW.
