Abstract
Description
本發明是有關於一種電子裝置，且特別是有關於一種具備主從角色切換功能的電子裝置。The present invention relates to an electronic device, and more particularly to an electronic device having a master-slave role switching function.
一般來說，行動裝置(例如手機或平板電腦)通常具有通用序列匯流排(Universal Serial Bus，或稱USB)埠，用以與其他電子裝置(例如鍵盤、滑鼠或隨身碟等等)的USB接頭相耦接以進行資料傳輸。由於上述行動裝置的USB埠與其他電子裝置的USB接頭的規格可能不同，導致上述行動裝置的USB埠須透過額外的USB轉接頭方能與其他電子裝置的USB接頭插接。除此之外，由於行動裝置的輕薄化已成趨勢，致使其通常僅具有一個USB埠，故此行動裝置須透過USB集線器(Hub)方能同時外接多個USB電子裝置。上述的種種情況皆導致此行動裝置在使用上受到侷限。In general, mobile devices (such as mobile phones or tablets) usually have a universal serial bus (USB), which is used for USB with other electronic devices (such as keyboard, mouse or flash drive, etc.). The connectors are coupled for data transfer. Since the USB port of the mobile device may be different from the USB connector of other electronic devices, the USB of the mobile device cannot be plugged into the USB connector of other electronic devices through an additional USB adapter. In addition, since the thinness of the mobile device has become a trend, so that it usually has only one USB port, the mobile device must be connected to a plurality of USB electronic devices through a USB hub. All of the above situations have led to the limitation of the use of this mobile device.
另外，使用者也可分別下載特定的應用程式及驅動程式至行動裝置及個人電腦(或筆記型電腦)，並透過個人電腦(或筆記型電腦)的無線網路介面使用鍵盤及滑鼠來控制行動裝置，如此一來，行動裝置無須透過USB集線器即可同時受控於鍵盤及滑鼠。然而，上述的應用程式可能會有相容性的問題而無法支援所有的行動裝置，導致此行動裝置在使用上依舊受限。In addition, users can download specific applications and drivers to mobile devices and personal computers (or laptops), and use the keyboard and mouse to control the wireless network interface of a personal computer (or laptop). The mobile device, in this way, the mobile device can be controlled by both the keyboard and the mouse without the need of a USB hub. However, the above application may have compatibility problems and cannot support all mobile devices, resulting in the limited use of this mobile device.
有鑑於此，本發明提供一種具備主從角色切換功能的電子裝置。透過電子裝置的主從角色的切換運作，致使外部裝置可透過電子裝置的通用序列匯流排埠而與電子裝置的至少一周邊裝置進行資料傳輸，以提高外部裝置及電子裝置在使用上的彈性。In view of the above, the present invention provides an electronic device having a master-slave role switching function.

詳細來說，在本發明的一實施例中，電子裝置100可運作於第一模式及第二模式，但本發明不限於此。當電子裝置100運作於第一模式時，主從模式切換模組170被設定為從屬模式(slave mode)，主從模式切換模組170可將第一外部裝置910設定為主要模式(host mode)，並導通第一通用序列匯流排埠150與周邊裝置130之間的傳輸路徑PH1，致使第一外部裝置910與周邊裝置130可透過傳輸路徑PH1進行資料傳輸。除此之外，當電子裝置100運作於第一模式時，主從模式切換模組170可斷開處理器110與第一通用序列匯流排埠150之間的傳輸路徑PH2，以及斷開處理器110與周邊裝置130之間的傳輸路徑PH3，其中傳輸路徑PH1、PH2及PH3為通用序列匯流排傳輸路徑。In detail, in an embodiment of the invention, the electronic device 100 can operate in the first mode and the second mode, but the invention is not limited thereto. When the electronic device 100 operates in the first mode, the master-slave mode switching module 170 is set to a slave mode, and the master-slave mode switching module 170 can set the first external device 910 to a master mode. And turning on the transmission path PH1 between the first universal sequence bus 150 and the peripheral device 130, so that the first external device 910 and the peripheral device 130 can transmit data through the transmission path PH1. In addition, when the electronic device 100 operates in the first mode, the master-slave mode switching module 170 can disconnect the transmission path PH2 between the processor 110 and the first universal sequence bus 埠 150, and disconnect the processor.
