基于USB接口的數(shù)據(jù)采集模塊的設計與實現(xiàn)Design and Implementation of USB-Based Data Acquisition Module路 永 伸(天津科技大學電子信息與自動化學院,天津300222)摘要文中給出基于USB接口的數(shù)據(jù)采集模塊的設計與實現(xiàn)。硬件設計采用以Adpc831與PDIUSBDI2為主的器件進行硬件設計,采用Windriver開發(fā)USB驅(qū)動,并用Visual C十十6.0對主機軟件中硬件接口操作部分進行動態(tài)鏈接庫封裝。關(guān)鍵詞USB 數(shù)據(jù)采集Adpc831 PDNSBDI2 Windriver動態(tài)鏈接庫Abstract T hed esigna ndim plementaitono fU SB-BasedD ataA cquisiitonM oduleis g iven.Th ec hips oluitonm ainlyw ithA dpc831a ndP DTUSBD12i sused for hardware design.
