μC/OS-II Goals Probably the most important goal of μC/OS-II was to make it backward compatible with μC/OS (at least from an application’s standpoint). A μC/OS port might need to be modified to work with μC/OS-II but at least, the application code should require only minor changes (if any). Also, because μC/OS-II is based on the same core as μC/OS, it is just as reliable. I added conditional compilation to allow you to further reduce the amount of RAM (i.e. data space) needed by μC/OS-II. This is especially useful when you have resource limited products. I also added the feature described in the previous section and cleaned up the code. Where the book is concerned, I wanted to clarify some of the concepts described in the first edition and provide additional explanations about how μC/OS-II works. I had numerous requests about doing a chapter on how to port μC/OS and thus, such a chapter has been included in this book for μC/OS-II.

两种解决方案 Richard just finished building his new house. Now the only thing the house misses is a cute little wooden fence. He had no idea how to make a wooden fence, so he decided to order one. Somehow he got his hands on the ACME Fence Catalogue 2002, the ultimate resource on cute little wooden fences. After reading its preface he already knew, what makes a little wooden fence cute. A wooden fence consists of N wooden planks, placed vertically in a row next to each other. A fence looks cute if and only if the following conditions are met: ?The planks have different lengths, namely 1, 2, . . . , N plank length units. ?Each plank with two neighbors is either larger than each of its neighbors or smaller than each of them. (Note that this makes the top of the fence alternately rise and fall.)

This source code has been tested under OpenWindows 2.0, Sun s X11/NeWS server. For Xlib programs that use KeyPress events you should either (1) set the FocusLenience resource to `True , or (2) specifically notify the window manager that you want to receive KeyPress/KeyRelease events (but only in programs that need these events).

When working with mathematical simulations or engineering problems, it is not unusual to handle curves that contains thousands of points. Usually, displaying all the points is not useful, a number of them will be rendered on the same pixel since the screen precision is finite. Hence, you use a lot of resource for nothing! This article presents a fast 2D-line approximation algorithm based on the Douglas-Peucker algorithm (see [1]), well-known in the cartography community. It computes a hull, scaled by a tolerance factor, around the curve by choosing a minimum of key points. This algorithm has several advantages: 这是一个基于Douglas-Peucker算法的二维估值算法。

可连接SQL，ORACLE等数据库。 首先建立SHOP用户，密码为SHOP，赋予连接和resource权限。再建立SHOP表空间，再建立表和触发器（在SQL源代码.doc里）并在PASSWORD表里添加新项name:‘admin ,psw: admin 这是管理员登陆帐户。 剩余的就看帮助文件吧。

非常适合内嵌式mp3播放,例如控制台!注意看压缩包里readme.doc 详细过程,在ARM及MIPS下通过 新建一个 wce application,选择 a simple windows ce application 在 1.tool->options->directories>include files里包含必要的头文件 D:\WINCE500\pubilc\directx\SDK\INC D:\WINCE500\pubilc\common\SDK\INC D:\WINCE500\pubilc\common\OAK\INC D:\WINCE500\pubilc\common\DDK\INC 2. >Library files D:\WINCE500\PUBLIC\DIRECTX\SDK\LIB\MIPSII\RETAIL D:\WINCE500\PUBLIC\COMMON\SDK\LIB\MIPSII\RETAIL D:\WINCE500\PUBLIC\COMMON\OAK\LIB\MIPSII\RETAIL 3.可能要在Project->Settings->link的object/library modules 加入 commctrl.lib coredll.lib ole32.lib oleaut32.lib uuid.lib strmiids.lib newres.h play.cpp play.vcw resource.h StdAfx.cpp StdAfx.h 下面为播放源码 #include "stdafx.h" #include<dshow.h> #include<streams.h> .......其实编译时的 object/library modules 只要看 sourse 文件包含哪个dll,或lib 就行

SimpliciTI™ -1.0.3.exe for CC11xx and CC25xx SimpliciTI is a simple low-power RF network protocol aimed at small (<256) RF networks. Such networks typically contain battery operated devices which require long battery life, low data rate and low duty cycle and have a limited number of nodes talking directly to each other or through an access point or range extenders. Access point and range extenders are not required but provide extra functionality such as store and forward messages. With SimpliciTI the MCU resource requirements are minimal which results in the low system cost.

WINDOWS调试工具很强大，但是学习使用它们并不容易。特别对于驱动开发者使用的WinDbg和KD这两个内核调试器（CDB和NTSD是用户态调试器）。本教程的目标是给予一个已经有其他调试工具使用经验的开发者足够信息，使其能通过参考WINDOWS调试工具的帮助文件进行内核调试。本文将假定开发者熟悉一般WINDOWS操作系统和进程的建立过程。 本文的重点是集成内核模式和用户态模式的图形化调试器WinDbg。KD在脚本和自动化调试中更有用，并且在资深程序员中拥有一定地位，但是本教程将集中讨论WinDbg，只会偶尔提到KD。 本文讨论的是Windows NT 4.0，Windows 2000或以后的版本，而且目标电脑的处理器基于X86架构。对于64位平台，将不会特别提及。 总之，本教程由简单介绍调试器的安装开始，大体分成2部分，基础知识和选择技术。基础知识包括基本调试命令和常用调试命令。选择技术是其他命令和在很多情况下都有用的调查方法。后者并不是调查象deadlocks, memory corruption或者resource leaks的唯一方法。第一次阅读本教程，你可能会跳过选择技术。你可以停止阅读本教程而转向微软调试器讨论组，也可以通过调试器的反馈e-mai解决更多的问题。
