Design Of Image Collector Based On Universal Searial USB2.0

This paper mainly discuss a system of design of image collect based on universal serial bus 2.0.It includes system-hardware, equipment firmware, USB2.0 equipment driver programme and apply programme's design.The design of hardware first adopts bt835 VideoStream Decoder, it is used to A/D switch and FPGA is used to the logical control and relax data. In the interface there are Cypress's EZ-USB FX2.It follows protocol of USB2.0. This chip includes a enhanced 8051 microcontroller, a serial interface engine, a USB transceiver, a on-chip ram holds 8.5kb, 4kb FIFO memorizer and a programmable peripheral interface in a single chip. In a word,FX2 is a entire and integrated design solved, it holds a little room and short exploited time. Driver programme uses VC++. In the WDM model completing apply programme and interface's function of USB2.0. Apply programme is used to control outside equipment and gain the data from outside equipment, so saving and displaying.This design of gaining image possesses of gaining image and collecting pc with the USB interface. Thus we can finish the communication.
