摘　　要：通用串行总线USB是近几年发展起来的新型的外设总线标准 ,特别是其即插即用和高达 12Mbit/s传输速率适合于笔记本电脑的线阵CCD数据采集接口。介绍了采用Philips公司通用串行总线芯片PDIUSBD12构成的线阵CCD的数据采集系统接口 ,讨论了采集接口的硬件设计、单片机程序设计、驱动程序和采集接口调试问题。USB(Universal Serial Bus) is the novelly developed external bus currently. With the 'plug and play' and the speed of 12Mbits/s, USB is the most available interface specification applicable to linear CCD data acquisition included the portable PC. The acquisition interface is introduced based on Universal Serial Bus for the linear CCD data acquisition system according the PDIUSBD12 chip of Philips Corp. The design of hardware, device driver and MCU firmware are discussed. The steps of system interface debug are given.
