PHP，即“PHP: Hypertext Preprocessor”，是一種廣泛用于 Open Source（開放源代碼）的尤其適合 Web 開發并可以嵌入 HTML 的多用途腳本語言。它的語法接近 C，Java 和 Perl，而且容易學習。該語言的主要目標是讓 Web 開發人員快速的書寫動態生成的網頁，然而，PHP 的功能并不局限于此。

Novell.Press.Linux.Kernel.Development linux內核開發的經典書籍之一 The Linux kernel is one of the most interesting yet least understood open-source projects. It is also a basis for developing new kernel code. That is why Sams is excited to bring you the latest Linux kernel development information from a Novell insider in the second edition of Linux Kernel Development. This authoritative, practical guide will help you better understand the Linux kernel through updated coverage of all the major subsystems, new features associated with Linux 2.6 kernel and insider information on not-yet-released developments. You ll be able to take an in-depth look at Linux kernel from both a theoretical and an applied perspective as you cover a wide range of topics, including algorithms, system call interface, paging strategies and kernel synchronization. Get the top information right from the source in Linux Kernel Development

本代碼為編碼開關代碼，編碼開關也就是數字音響中的 360度旋轉的數字音量以及顯示器上用的（單鍵飛梭開 關）等類似鼠標滾輪的手動計數輸入設備。 我使用的編碼開關為5個引腳的，其中2個引腳為按下 轉輪開關（也就相當于鼠標中鍵）。另外3個引腳用來 檢測旋轉方向以及旋轉步數的檢測端。引腳分別為a,b,c b接地a，c分別接到P2.0和P2.1口并分別接兩個10K上拉 電阻，并且a，c需要分別對地接一個104的電容，否則 因為編碼開關的觸點抖動會引起輕微誤動作。本程序不 使用定時器，不占用中斷，不使用延時代碼，并對每個 細分步數進行判斷，避免一切誤動作，性能超級穩定。 我使用的編碼器是APLS的EC11B可以參照附件的時序圖 編碼器控制流水燈最能說明問題，下面是以一段流水 燈來演示。

【問題描述】 在一個N*N的點陣中，如N=4,你現在站在（1，1），出口在（4，4）。你可以通過上、下、左、右四種移動方法，在迷宮內行走，但是同一個位置不可以訪問兩次，亦不可以越界。表格最上面的一行加黑數字A[1..4]分別表示迷宮第I列中需要訪問并僅可以訪問的格子數。右邊一行加下劃線數字B[1..4]則表示迷宮第I行需要訪問并僅可以訪問的格子數。如圖中帶括號紅色數字就是一條符合條件的路線。 給定N，A[1..N] B[1..N]。輸出一條符合條件的路線，若無解，輸出NO ANSWER。（使用U，D，L，R分別表示上、下、左、右。） 2 2 1 2 （4，4） 1 （2，3） （3，3） （4，3） 3 （1，2） （2，2） 2 （1，1） 1 【輸入格式】 第一行是數m (n < 6 )。第二行有n個數，表示a[1]..a[n]。第三行有n個數，表示b[1]..b[n]。 【輸出格式】 僅有一行。若有解則輸出一條可行路線，否則輸出“NO ANSWER”。

This book is about writing TinyOS systems and applications in the nesC language. This chapter gives a brief overview of TinyOS and its intended uses. TinyOS is an open-source project which a large number of research universities and companies contribute to. The main TinyOS website, http://www.tinyos.net, has instructions for downloading and installing the TinyOS programming environment. The website has a great deal of useful information which this book doesn’t cover, such as common hardware platforms and how to install code on a node.

LUFA (Lightweight USB Framework for AVRs) is my first foray into the world of USB. Originally based on the AT90USBKEY from Atmel, it is an open-source, driver for the USB-enabled AT90USBXXX AVR microcontroller series, released under the permissive MIT License (see documentation or project source for full license details). Currently, the AT90USB1286, AT90USB1287, AT90USB646, AT90USB647, AT90USB162, AT90USB82, ATMEGA16U4 and ATMEGA32U4 AVR microcontrollers are supported by the library. Supported boards are the USBKEY, STK525, STK526, ATAVRUSBRF01 and the RZUSBSTICK.
