EV-DO

EVDO(EV-DO)实际上是三个单词的缩写:Evolution(演进)、DataOnly。其全称为:CDMA20001xEV-DO,是CDMA20001x演进(3G)的一条路径的一个阶段。这一路径有两个发展阶段,第一阶段叫1xEV-DO,即“DataOnly”,它可以使运营商利用一个与IS-95或CDMA2000相同频宽的CDMA载频就可实现高达2.4Mbps的前向数据传输速率,已被国际电联ITU接纳为国际3G标准,并已具备商用化条件。第二阶段叫1xEV-DV。1xEV-DV意为“DataandVoice”,它可以在一个CDMA载频上同时支持话音和数据。

    AC97 Sample Driver and Related Code Samples. This directory contains a sample AC97 adapter driver and several related code samples. These samples need to be compiled with the Windows .NET or Windows XP build environment but are binary compatible with older operating systems like Windows 2000. To build the samples, enter any Windows .NET or Windows XP build environment and run build –cZ from this directory. The AC97 sample driver also runs in Windows 98 Second Edition or Windows Me, but the property page DLL and control panel application do not. For more information, please refer to the readme.htm files in each subdirectory. The INF file in the driver directory installs all of the samples in the subdirectories. The header file in this directory defines the private property used by each of the samples.

  • 此函数把SPI的读写功能集成在一块

    此函数把SPI的读写功能集成在一块,传递的val既是向SPI写的数据,也是从SPI读取的数据,只需要在执行读或写之前把MCU的I/O脚设置成相应的输出或输入即可。(因为在大部分应用中,是把SPI的DI和DO相连并用MCU的一个IO口来读写)。

  • 一种比较好的抗锯齿算法 Add myaa.m to your path and enjoy anti-aliased professionally looking graphics in Matla

    一种比较好的抗锯齿算法 Add myaa.m to your path and enjoy anti-aliased professionally looking graphics in Matlab at any time. Myaa works with any kind of graphic (3-D, plots, scatterplots, ...) and even adds anti-aliasing to text, ui controls and grids. Myaa is ideal for complex, cluttered and saturated plots. See attached screenshot for a demonstration. More examples included in the code, just run help myaa . Curiosa: For those of you who publish your code often, an undocumented anti-aliasing option is included in the snapnow.m function in Matlab. To publish a file called test.m you can do: opts.figureSnapMethod = antialiased publish( test.m ,opts) However, you will have more control over the process using myaa, which is also the best choice when using Matlab interactively.

    If you d like to create web-based applications easily, then this book is for you. More importantly, it shows you how to do that with joy and feel good about your own work! You don t need to know servlet or JSP while your productivity will be much higher than using servlet or JSP directly. This is possible because we re going to use a library called "Tapestry" that makes complicated stuff simple and elegant.

  • Get more out of your legacy systems: more performance, functionality, reliability, and manageability

    Get more out of your legacy systems: more performance, functionality, reliability, and manageability Is your code easy to change? Can you get nearly instantaneous feedback when you do change it? Do you understand it? If the answer to any of these questions is no, you have legacy code, and it is draining time and money away from your development efforts.

    DSR-UU is a DSR implementation that runs in Linux and in the ns-2 network simulator. DSR-UU implements most of the basic DSR features specified in the DSR draft (version 10). One big exception is flow extensions. DSR-UU does NOT use ARP, so do not be surprised if you do not see ARP traffic. DSR-UU instead uses its own neighbor table that sets up the MAC-to-IP translation during route discovery.

    Use the links below to download a source distribution of Ant from one of our mirrors. It is good practice to verify the integrity of the distribution files, especially if you are using one of our mirror sites. In order to do this you must use the signatures from our main distribution directory. Ant is distributed as zip, tar.gz and tar.bz2 archives - the contents are the same. Please note that the tar.* archives contain file names longer than 100 characters and have been created using GNU tar extensions. Thus they must be untarred with a GNU compatible version of tar. If you do not see the file you need in the links below, please see the master distribution directory or, preferably, its mirror.
