Research Of Virtual Instruments System Based On USB

This project mainly use the USB theory. Virtual instruments theory, MCU theory and some knowledge include software and hardware to perform the research of Virtual instruments system based on USB.USB possess the characters of Plug-and-Play and it also convenience for using, LabVIEW is a powerful application software engineering. For putting both of them in my project, I had accomplished circuit design, circuit board making, compiling firmware programme of MCU, compiling WDM programme, LabVIEW programme and so on, and involving knowledge have C/C++, Assembly Language , MCU simulator, USB bus, 98DDK, Protel, LabVIEW, LabWINDOWS/CVI and so on. After integration debugging, it has been successful to transmit data from bottom hardware to application software and accomplish the initial prototype of virtual instruments system based on USB.
