【摘要】 USB是近年来流行的计算机外设接口标准。它具有方便易用、传送速度快、价格低廉等特点，已经被广泛应用于各种数据传输设备。USB接口技术为PC主机和外设之间的数据传输提供了便捷的解决方案。论文研究了USB总线的物理拓扑结构、总线逻辑拓扑结构、USB的数据传输类型和USB通信协议，以及USB技术在嵌入式领域中的应用，讨论了硬件电路的构建，研究USB接口芯片和微处理器的器件选择、性能特点和电路组成。在这基础上对固件程序的开发作了详细探讨，包括固件的设计目标、工作原理和固件程序的结构和设计过程等。最后通过对WDM驱动程序和应用程序的研究，实现了数据传输和语音录放等功能。更多还原

【Abstract】 USB has been widely used in various kinds of data transferring equipment in recentyears. With a high data transfer speed, it is convenient, cheap and easy to handle. USBinterface technology provides a wonderful solution for the data transmission between PCand other equipments.The paper is described in five parts. First part briefly introduces the history of USBinterface, and the characteristic of USB. Second part introduces USB physics architecture,USB logic architecture, data transfer type, USB communication protocol and theapplication in embedded systems. Then the third part studies the design of the hardwarecircuit, mainly about the USB interface and microcomputer. The fourth part emphasize onthe design of firmware program, introduces the goal of firmware design, the workprincipium of firmware, and the makeup and design of firmware. Finally, the fifth partdeals with how to write a WDM driver and how to develop application, and achieves datatransfer and voice recording and playing.更多还原
