LPC2148 USB Audio Device Example This USB example project implements an USB Audio Device that connects via the USB interface to the PC. It may be used on the following devices: LPC2141 LPC2142 LPC2144 LPC2146 LPC2148 An USB Audio Device (HID) does not require any special USB driver, since the USB Audio support is already built into Windows 2000 and Windows XP. Therefore USB Audio devices can be directly connected to the computer. This example project is designed to work with Keil MCB2140 Evaluation Board. Refer to Running USBAudio for information on how to operate this example project.

CBC下写的串口编程，API函数实例 I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.

．数据结构 假设有M个进程N类资源，则有如下数据结构： MAX[M*N] M个进程对N类资源的最大需求量 AVAILABLE[N] 系统可用资源数 ALLOCATION[M*N] M个进程已经得到N类资源的资源量 NEED[M*N] M个进程还需要N类资源的资源量 2．银行家算法 设进程I提出请求Request[N]，则银行家算法按如下规则进行判断。 (1)如果Request[N]<=NEED[I，N]，则转(2)；否则，出错。 (2)如果Request[N]<=AVAILABLE，则转(3)；否则，出错。 (3)系统试探分配资源，修改相关数据： AVAILABLE=AVAILABLE-REQUEST ALLOCATION=ALLOCATION+REQUEST NEED=NEED-REQUEST (4)系统执行安全性检查，如安全，则分配成立；否则试探险性分配作废，系统恢复原状，进程等待。 3．安全性检查 (1)设置两个工作向量work=AVAILABLE；FINISH[M]=FALSE (2)从进程集合中找到一个满足下述条件的进程， FINISH[i]=FALSE NEED<=work 如找到，执行(3)；否则，执行(4) (3)设进程获得资源，可顺利执行，直至完成，从而释放资源。 work=work+ALLOCATION FINISH=TRUE GO TO 2 (4)如所有的进程Finish[M]=true，则表示安全；否则系统不安全。

<===== 关于 GANT 鼠标集 (M) =====> 此“GANT 鼠标集 (M)”包含黄色和蓝色两种颜色主题，每种颜色主题分别有两套鼠标。换句话说，这个鼠标集共提供4套鼠标，分别放在4个文件夹内。 这里，我简单介绍一下每套鼠标，以所在文件夹名来指代： - yellow_normal_24x24：黄色，9个 ani 文件（动态鼠标）和6个 cur 文件（静态鼠标），与预览图中所示一样； - yellow_colorful_24x24：黄色，除“work in Background.ani”和“Wait.ani”两个鼠标为12色变换之外，其他13个鼠标与上面一套完全相同； - blue_normal_24x24：蓝色，9个 ani 文件和6个 cur 文件； - blue_colorful_24x24：蓝色，除“work in Background.ani”和“Wait.ani”两个鼠标为12色变换之外，其他13个鼠标与上面一套完全相同。 所有鼠标的尺寸都是 24像素 x 24像素。 感谢 mattahan 准许我使用他的 GANT 图标来制作这几套鼠标！ 同时非常感谢 cyberchaos05（http://cyberchaos05.deviantart.com），他为我制作了鼠标的预览图。 “GANT 鼠标集 (M)”仅供个人使用，不得用于任何商业目的！

The subject which is to us propos¨¦ is as follows: calculation of the degr¨¦ d¡ ¯ inconsistance d¡ ¯ un logical program possibilist in C++. We thus work on a logical program possibilist, it be-¨¤-statement a logical program resulting from non-classique logic. The goal first of this project is of d¨¦ terminer if a logical program is consisting or not of share the calculation of sound degr¨¦ d¡ ¯ inconsistance.

This book is about using Python to get jobs done on Windows.This intended to be a practical book focused on tasks. It doesn t aim to teach Python programming, although we do provide a brief tutorial. Instead, it aims to cover:How Python works on Windows The key integration technologies supported by Python on Windows, such as the Win32 extensions, which let you call the Windows API, and the support for COM Examples in many topic areas showing what Python can do and how to put it to work.

Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.
