中文摘要: USB(Universal Serial Bus)是目前应用非常广泛的一种总线形式.其即插即用、热插拔、接口体积小巧等优点给计算机外设连接技术带来重大变革.μCOS-II是一个源码公开、完整的、可移植、可固化、可裁剪的嵌入式实时操作系统,可以方便地移植到多种微处理器上.以在新太科技实际工作中的LPC2378读卡器为例,详细介绍μCOS-II中USB主机系统的设计.
Abstract:USB (Universal Serial Bus) is a far widely used bus. It has many advantages, such as plug and play, hot plug and small volume of the interface, which have hugely changed the development of the technology of connecting computers to external equipments．μCOS-II is an open-source, complete, portable, ROMable, well custom real-time embedded operating system, which can be easily ported to a variety of microprocessor. The paper uses the LPC2378 reader card which I had used in the SUNTEK as an example to introduce the design of USB host system in μCOS-II.
