VHDL语言实验系统——后台PC机支持程序设计 摘 要 USB产业近几年的迅猛发展，使得传输速度和性能上都有了大幅度的提高，也使得该技术的优势越来越明显，应用也相应的越来越广泛。学习和应用单片机的热潮始终不减，特别是MCS51系列。实际上，从应用通用数字集成电路系统到广泛应用单片机，是我国电子设计在智能化应用水平上质的飞跃。 本文主要介绍的是PC机上驱动程序的编写，主要包括Windows USB驱动程序设计，即编写用户程序以及内核驱动并让其进行通信。在本文中，首先介绍了USB的发展现状，接着介绍了编写驱动程序需要用到的一些知识，其中包括：Windows 驱动程序，USB设备，USB内核驱动等的介绍。最后给出详细的开发技术以及设计程序步骤。最后对这次毕业设计的过程进行了总结和收获。 关键词： USB驱动 设备驱动程序 PC机 WDM ABSTRACT USB technology has advanced by swift and violent in recent years，the transmission speed and performance have improved substantially, but also makes the technology more and more obvious, more and more extensive applications. Learning and application of microprocessor has reduced the fever, especially MCS51 series. In fact, the universal digital integrated circuits from the application systems to the wider use of single-chip, is the application of intelligent electronic design level in a qualitative leap. This paper mainly introduces the PC, the driver of the preparation, including the design of Windows USB drivers, that is, user programs and kernel drivers and their communication. In this article, first introduced the development of USB, and then introduced the drivers needed to prepare some of the knowledge, including: Windows drivers, USB devices, USB kernel drivers, etc. introduction. Finally, detailed procedures for the development of technology and design steps. The final design of the graduation process and harvest summary.
