  • 基于USB接口的數據采集模塊的設計與實現

    基于USB接口的數據采集模塊的設計與實現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接口的數據采集模塊的設計與實現。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USB驅動,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鏈接庫封裝。關鍵詞USB 數據采集Adpc831 PDNSBDI2 Windriver動態鏈接庫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. The USB drive is developed場Wmdriver, and the operation on the hardware interface is packaged into Dynamic Link Libraries場Visual C++6.0.  Keywords USB DataA cquisition Adttc831 PDfUSBD12 Windriver0 引言US B總 線 是新一代接口總線,最初推出的目的是為了統一取代PC機的各類外設接口,迄今經歷了1.0,1.1與2.0版本3個標準。在國內基于USB總線的相關設計與開發也得到了快速的發展,很多設計者從各自的應用領域,用不同方案設計出了相應的裝置[1,2]。數據采集是工業控制中一個普遍而重要的環節,因此開發基于USB接口的數據采集模塊具有很強的現實應用意義。雖然 US B總線標準已經發展到2.0版本,但由于工業控制現場干擾信號的情況比較復雜,高速數據傳輸的可靠性不容易被保證,并且很多場合對數據采集的實時性要求并不高,開發2.0標準產品的成本又較1.1標準產品高,所以筆者認為,在工業控制領域,目前開發基于USB總線1.1標準實現的數據采集模塊的實用意義大于相應2.0標準模塊。

  • The Kannel Open Source WAP and SMS gateway works as both an SMS gateway, for implementing keyword b

    The Kannel Open Source WAP and SMS gateway works as both an SMS gateway, for implementing keyword based services via GSM text messages, and a WAP gateway, via UDP. The SMS part is fairly mature, the WAP part is early in its development. In this release, the GET request for WML pages and WMLScript files via HTTP works, including compilation for WML and WMLScript to binary forms. Only the data call bearer (UDP) is supported, not SMS.

  • TLV1544與TMS320VC5402通過串行口連接

    TLV1544與TMS320VC5402通過串行口連接,此時,A/D轉換芯片作為從設備,DSP提供幀同步和輸入/輸出時鐘信號。TLV1544與DSP之間數據交換的時序圖如圖3所示。 開始時, 為高電平(芯片處于非激活狀態),DATA IN和I/OCLK無效,DATAOUT處于高阻狀態。當串行接口使CS變低(激活),芯片開始工作,I/OCLK和DATAIN能使DATA OUT不再處于高阻狀態。DSP通過I/OCLK引腳提供輸入/輸出時鐘8序列,當由DSP提供的幀同步脈沖到來后,芯片從DATA IN接收4 b通道選擇地址,同時從DATAOUT送出的前一次轉換的結果,由DSP串行接收。I/OCLK接收DSP送出的輸入序列長度為10~16個時鐘周期。前4個有效時鐘周期,將從DATAIN輸入的4 b輸入數據裝載到輸入數據寄存器,選擇所需的模擬通道。接下來的6個時鐘周期提供模擬輸入采樣的控制時間。模擬輸入的采樣在前10個I/O時鐘序列后停止。第10個時鐘沿(確切的I/O時鐘邊緣,即上升沿或下降沿,取決于操作的模式選擇)將EOC變低,轉換開始。
