摘要
设计了一个基于USB2.0接口的CMOS图像采集系统。详细介绍了USB数据接口的固件设计、驱动程序开发以及上层驱动程序的设计。该系统采用CYPRESS公司的EZ-USBFX2芯片作为USB通信及主控芯片,采用块传输模式。试验结果表明,该系统完全符合USB2.0的协议规范,可以很好地满足实时图像传输的要求。
A kind of CMOS video collecting system which transfers data based on Universal Serial Bus, is put forward the design of firmware, driver program and application programming are introduced. The system uses USB2.0 interface chip EZUSB-FX2 as a main transmission unit. Finally the result given by experiment shows that the system fits the criterion of USB absolutely, shooting the goal of the image transferring has reached the satisfactory result.
