USB操纵杆在LabWindows/CVI中的实现

Realization of the USB Joystick in LabWindows/CVI

LabWindows/CVI工具应用广泛、开发方便。USB接口操纵杆应用在飞机操纵杆仿真中,逼真度及交互性都十分合适。但CVI不提供直接支持USB接口的函数库,在分析了Labwindows/CVI环境中USB设备数据操作方法的基础上,针对USB操作杆的特殊性,采用Windows SDK、DirectX与CVI结合,实现了在CVI环境中对USB操作杆数据的通讯。

The extensive application and convenient exploitation are the advantages of LabWindows/CVI.The fidelity and interactant are suitable by the USB joystick applied in plane.However CVl doesn＇t offer the direct function for USB interface,The article analyzed the data manipulation methods of the USB equipment in the environment of LabWindows/CVl,ln allusion to the particularity of USB manipulator,Integrated the Windows SDK,DirectX and CVI, it achieved the USB manipulator＇s data communication in the environment of CVl.
