【摘要】 红外线，简称IR，是一种无线通讯方式，常常可以使用红外线进行无线数据的传输，能够取代复杂的连接线。自1974年发明红外线以来，它已经过风风雨雨二十多年的发展，如今，已经是一种很成熟的传输技术。同时，作为计算机外设接口技术的重要变革，USB在传统的计算机组织结构的基础上，引入网络的拓扑结构思想。其具有终端用户的易用性、广泛的应用性、带宽的动态分配、优越的容错性能、较高的性能价格比等特点，方便了外设的增添，适应了现代计算机多媒体的功能拓展，已逐步成为计算机的主流接口。 本论文的研究目的是结合USB技术和红外线接口技术，研究开发USB-IrDA适配器，该系统广泛用于手机，掌上电脑等带红外接口的设备和PC机的通信。具有即插即用等USB接口所有的特点。 本论文研究主要涉及硬件电路设计，单片机汇编语言，驱动程序设计等技术。 论文首先讨论了USB接口协议和红外线接口协议，这是实现该系统的理论技术，其次提出了电路的总体框图，详细分析了硬件电路的实现和适配器驱动程序的设计方法。更多还原

【Abstract】 Infrared, simply called IR, is one type of wireless communication mode, wireless transmission can not only used in processing data , but also replaced the old mode of complex cable connections.Through its developing history past more than twenty years, IR that invented in 1974 now became the most stable transmission technology.At the same time, the introduction of USB on external interface technique, acts as a major change on the basic structure of the classical computers. The existence of the USB in the computer results on the following properties ,easy usage to the end-user ,broadly applicable ,predominant free-error capability ,best performance/price ratio, etc, convenience of adding external hardware, adoption of modern computer’s multimedia development, as a consequently it became the popular interface of a computer.The main purpose of this thesis is to research and develop an USB-IrDA adapter system with the combination of USB technologies and IrDA interface technologies. This kind of adapter system could be applicable in the communications of devices with IrDA interface such as mobile phone, PDA, etc., and supports all the features of USB interface such as plug and play (PnP).The main research scope of this thesis, concerns of hardware circuit design, MCU assembly language, driver programming technologies, etc.Firstly the thesis introduced USB interface protocol and IrDA interface protocol which are the mainly theories and technologies needed in the implement of the system. Then, it brought forward the main frame of the circuit for the system and analyzed the implement of hardware circuit and designing method of driver program for the adaptor in details.更多还原
