Abstract
The whole realization process of an 8-channel USB data Acquisition system is discussed in this paper.The data acquisition system uses USB interface chip PDIUSBD12 and extended micro-controller of 51 series ADμC812 , which are the most popular chips in use, to sample signals and transmit data. The realization of firmware and application is also presented.
