摘要
从硬件设计、固件设计、设备驱动程序设计和应用软件设计4个方面阐述了基于U SB总线的数据采集系统.系统使用了高性能的U SB专用芯片CY 7C 64613,给出了硬件电路图.该系统具有速度快、即插即用、可移动、使用方便、低功耗等特点.但是U SB具有诸如协议复杂、编写设备驱动程序要考虑很多细节,文中通过调用W in32的AP I函数与设备通信,即与内置的驱动程序通信,克服了上述缺点.
This paper illustrated the data acquisition system based on USB. including hardware designing, firmware designing, devices' driver application designing and application software designing. In system, the high-programme chip called CY7C64613 was used. At the same time, the hardware circuit's pictures were given. In a word, the characters of system were more faster, pluy and play, mobile, quite convenient and lower power, but USB bus have some troubles such as complex protocols, compiling complex device's driver. Therefor, the paper used Win32's API functions communicatiing with devices, namely which communicated with the inner driver overcame the faults.
