Design and Implementation Of Embedded Data Acquisition System Based on USB and Flash Multimediacard Memory

Main research in this paper is the DA(data acquisition) system design which based on the USB and MMC. According a USB's chip correlation hardware information, USB protocol, DA systematic structure and singlechip computer information, a hardware development solution was come out in the design. This solution consists of the data acquisition module hardware development design, singlechip computer data acquisition program development , USB's installation interface design and debug, embedded software(SW) and file system design. Finally we achieves the DA system which is more speedly, without delay and more dependable.
