设备驱动程序

At first this paper compendiously introduces the structure of Water Quality Online Monitor System; after that this paper illuminates how to design and program driver of USB device under Windows CE in deeply and implements the vedio capture of Water Quality Online Monitor System.

在对系统实现涉及的相关技术讨论的基础上，论文详细的讨论了Windows CE下USB设备的驱动程序开发；并实现了在线水质监控系统中视频采集的功能，即USB摄像头驱动程序的实现。

In view of the above steps a second phenomenon, clone the operating system is to store the default camera driver in C: \ Windows \ Driver \ Camera \ 301P the following folder, when you click on the new CD-ROM drive to install the camera, the system will not prompt already exists there and the camera drivers to uninstall this driver, please find this folder and removed; step II, first to install a new camera driver, and then plug in the camera loaded with hardware, the installation is complete restart the computer after normal use; step three, repeat the above two steps do not directly click on the new CD-ROM installation the latest drivers, plug in the camera after the system detects new hardware and auto-complete loading hardware drivers; step four, entered the Device Manager, can see the image processing equipment has been successfully installed, but when you open the "AMCAP" Preview images can not be preview, black and white, black phenomenon; five steps to the right mouse button on the image processing equipment "Vimicro USB PC Camera (ZC0301PL)" update driver, a dialog box appears choose "from the list or designated as the location of the installation steps to choose the next six to choose "Do not Search" and enter "to install from the floppy disk interface.

针对以上第二种现象步骤一、克隆操作系统是将摄像头驱动默认存放在C：\Windows\Driver\Camera\301P文件夹下面，当你点击新的摄像头驱动光盘安装时，系统不会提示已经存在有摄像头驱动并把此驱动卸载，请把这个文件夹找到并删除掉；步骤二、先安装新的摄像头驱动，再插上摄像头装载硬件，安装完成后重新启动电脑后可以正常使用；步骤三、不需重复以上两个步骤，直接点击新的光盘安装最新的驱动，插上摄像头后系统检测到新硬件，并自动完成硬件驱动装载；步骤四、进入到设备管理器中，，可以看到图像处理设备已经成功安装，但当你打开"AMCAP"预览图像时会出现无法预览、白屏、黑屏现象；步骤五、把鼠标右键放在图像处理设备的"Vimicro USB PC Camera（ZC0301PL）"更新驱动程序，出现对话框后选择"从列表或指定为位置安装步骤六选择下一步后选择"不要搜索"，进入"从软盘安装界面。

An unintelligent process that continues forever in the face of failures can generate thousands of retries per second; if your driver prints a "my device is broken" message every time, it could create vast amounts of output and possibly hog the CPU if the console device is slow－to interrupts can be used to driver the console, even if it is a serial port or a line printer.

一个设计糟糕的进程在遇到错误时会进入死循环状态，每秒中内会对函数进行上千次的重调；如果你的驱动程序每次都显示"设备损坏"的消息，那将会产生大量的输出信息，并且当控制台设备的是低速运行设备时有可能会独占 CPU ，即使它是一个串口或是一个行式打印机。

Any special drivers, such as the ones for small computer system interface adapters, are loaded from the adapter, and the BIOS displays the information. The BIOS then looks at the sequence of storage devices identified as boot devices in the CMOS Setup.

一个特殊的设备驱动，如一些SCSI设备需要的驱动程序，由这个设备来装载，BIOS来显示这些信息。

With that ,we decide to use WINDDK to compile the driver program which is closer to hardware and can be handled agilely after compare the several popular way of making WDM driver program, in despite of it will bring more difficulty.

在介绍了驱动程序的安装方法后，详细介绍了应用程序的编制和驱动程序和应用程序的连接方法，以及如何利用GUID找到设备接口名这一关键步骤。

The device computes degree of slip on the basis of wheel rpm calculated by the ABS sensors and activates two different control systems to restore grip: when an excessive power demand causes both drive wheels to slip (e.g. in the case of aquaplaning or when accelerating over an unsurfaced, snowy or icy road), it reduces engine torque by reducing the throttle opening angle and thus air flow; if only one wheel slips (e.g. the inside wheel following acceleration or dynamic load changes), this is automatically braked without the driver touching the brake pedal.

该设备计算对车轮转速传感器的ABS的基础上计算的滑移程度和激活两个不同的控制系统，以恢复地力：当一个权力过大，导致需求驱动车轮都滑倒在打滑的情况（例如，通过一个或加速unsurfaced，积雪或结冰的道路），它减少了通过减少节气门开度角，从而空气流通发动机扭矩；如果只有一个轮子单（如车轮内的下列加速或动态负载变化），这是自动完成，无需驱动程序的触摸制动刹车踏板。

I also thought that the beginning of the phenomenon of the failure was due to display card driver caused the destruction, so I right-click the desktop system, the "My Computer" icon on the shortcut menu from the pop-up the implementation of "property "command, open the System Properties settings window, click the window of the" hardware "tab, and in the corresponding tab page, click" Device Manager "button, open the device list window, use the mouse to start the window "Show card" option, and then double-click the mouse "standard VGA graphics adapter" project, open the corresponding project page the driver tab, click the tab page in the "Uninstall" button to display the current card driver procedure removed, and then restart the computer system, then let the system automatically re-installed the graphics card driver.

开始阶段笔者还以为该故障现象是由于显示卡驱动程序遭到破坏引起的，于是笔者用鼠标右键单击系统桌面中的&我的电脑&图标，从弹出的快捷菜单中执行&属性&命令，打开系统的属性设置窗口，单击该窗口中的&硬件&标签，并在对应的标签页面中单击&设备管理器&按钮，打开系统的设备列表窗口，用鼠标展开该窗口中的&显示卡&选项，再用鼠标双击&标准 VGA 图形适配器&项目，打开对应项目的驱动程序标签页面，单击该标签页面中的&卸载&按钮，来将当前的显示卡驱动程序删除掉，之后将计算机系统重新启动了一下，同时让系统自动重新安装了显示卡驱动程序。

Then, for the multimedia device's sake, the Kernel stream driver's principle, architecture and the development process are analyzed in details.

本文首先对Windows WDM驱动程序进行了研究，深入分析了针对多媒体设备设计的内核流驱动架构的工作原理、体系架构和开发流程。

it is very important to compile driver connecting operating system with corresponded hardware device.based on stream interface driver model,the design of spi driver in embedded operating system win ce in development environment of platform builder 4.2 and design method are introduced and analysed,realizing virtual address map,key code and the relationship between driver and spi application program in evc program environment is discussed.driver and corresponded application program can be operated on fs_ep9315 development platform of ucdragon rightly.experience indicates the methord is right and feasible.

编写联系操作系统和相应硬件设备的驱动程序至关重要。在platform builder 4.2开发环境下，基于流接口驱动程序模型，详细阐述嵌入式操作系统win ce下ep9315芯片的spi接口的驱动程序设计方法，就设计步骤、虚拟地址映射实现和关键程序代码编写等进行具体分析，并论述驱动程序与evc编程环境下spi应用程序之间的关系。驱动程序和相应应用程序能正确运行于优龙的fs_ep9315开发平台。实践证明，该方法正确可行。

Such as Loadable Kernel Modules in Linux or device drivers in Microsoft Windows.

这里上面的朋友刚才倒了过来，应该是：比如Linux中的可加载模块和Windows中的设备驱动程序。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
