概論

本文介紹了一個事實上的USB設備－MiniNurse(MN)。理想中的MN具有一些標準的輸入接口，如溫度探頭、光探頭、濕度探頭等，以及標準輸出接口，如各類電器的控制等。這正是MN命名的由來。

這個版本的MN尚未實現如此豐富的功能。目前她的固件和驅動程序可以完成USB的標準請求，作為USB設備這是必須的。在應用程序的控制下，她還能夠控制其上的兩個LED(如果換用合適的繼電器，可以直接控制直接啟動的電器，如臺燈)。

整個項目包括：
	硬件設計：芯片的選擇、制作PCB( 印刷電路板)以及調試
	固件設計：整體構架、規劃、調試
	驅動程序：構架、調試以及幾個測試用的應用程序

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
