The Scxi Data Acquisition System Software And The Design Of The Usb Communication Port

This paper included two sections: the first section was the realizing of software of SCXI Data Acquisition System; the second was the design of USB抯 communication interface. In first section, We elaborated on the software of SCXI data acquisition system using Lab Windows/CVI software platform. We designed waveform ~ DC and help UI. The whole software was very easy to user and UI was very friendly and directly. It run very well by checking and using. It got a good result. Secondly, this paper also introduced the USB 憇 protocol, and basing on it, we designed the USB抯 hardware and software.
