As a new interface caters for rapid development of computer peripheral equipment , universal serial bus ( for short usb ) dispels astriction of communication through traditional serial port and parallel port . it is very suitable for real time image data transmission , which requires high speed . this theme describes two - circuit systems , which utilize usb interface to data from a digital image sensor to pc 為了迎合計算機上設(shè)的快速發(fā)展以及消除計算機外設(shè)通過串、并口的通訊的局限性,出現(xiàn)了新的計算機外設(shè)接口usb (通用串行總線) ,這種新型接口對于實時的視頻傳輸很適用,本文設(shè)計了兩套電腦眼基于ez - usb2131q的usb接口系統(tǒng)。
