USB驱动使用比较详细的一个例子

概论

本文介绍了一个事实上的USB设备－MiniNurse(MN)。理想中的MN具有一些标准的输入接口，如温度探头、光探头、湿度探头等，以及标准输出接口，如各类电器的控制等。这正是MN命名的由来。

这个版本的MN尚未实现如此丰富的功能。目前她的固件和驱动程序可以完成USB的标准请求，作为USB设备这是必须的。在应用程序的控制下，她还能够控制其上的两个LED(如果换用合适的继电器，可以直接控制直接启动的电器，如台灯)。

整个项目包括：
	硬件设计：芯片的选择、制作PCB( 印刷电路板)以及调试
	固件设计：整体构架、规划、调试
	驱动程序：构架、调试以及几个测试用的应用程序

Abstract

Here we introduce a defacto USB device named as MiniNurse (short for MN). Maybe as a mature product, at last MN will have some standard INPUT port, such as temperature-sensor/photosensitive-sensor/humidity-sensor; and some standard OUTPUT port, such as some kinds of controller for equipments.  This is the reason for the name of "MiniNurse".

But now, there is a lack of those function. At this moment her FirmWare and Driver can work out USB standa request like all USB devices. And under a Application, you can turn on or off the LEDs on MN(of course, choose suitable relay, MN can control switch-type equipm like desk lamp).

The whole project includes: 
	HardWare Design:	make sure which chip(s) should be installed and make PCB(Printed Circuit Board) and test
	FirmWare Design:	make sure the whole architecture and the layout of some data structure and test/debug
	Driver Design: 	study the main frame of Linux USB Driver and some kernel knowledge and test it and some demo applications
