Novell.Press.Linux.Kernel.Development linux内核开发的经典书籍之一 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

本代码为编码开关代码，编码开关也就是数字音响中的 360度旋转的数字音量以及显示器上用的（单键飞梭开 关）等类似鼠标滚轮的手动计数输入设备。 我使用的编码开关为5个引脚的，其中2个引脚为按下 转轮开关（也就相当于鼠标中键）。另外3个引脚用来 检测旋转方向以及旋转步数的检测端。引脚分别为a,b,c b接地a，c分别接到P2.0和P2.1口并分别接两个10K上拉 电阻，并且a，c需要分别对地接一个104的电容，否则 因为编码开关的触点抖动会引起轻微误动作。本程序不 使用定时器，不占用中断，不使用延时代码，并对每个 细分步数进行判断，避免一切误动作，性能超级稳定。 我使用的编码器是APLS的EC11B可以参照附件的时序图 编码器控制流水灯最能说明问题，下面是以一段流水 灯来演示。

【问题描述】 在一个N*N的点阵中，如N=4,你现在站在（1，1），出口在（4，4）。你可以通过上、下、左、右四种移动方法，在迷宫内行走，但是同一个位置不可以访问两次，亦不可以越界。表格最上面的一行加黑数字A[1..4]分别表示迷宫第I列中需要访问并仅可以访问的格子数。右边一行加下划线数字B[1..4]则表示迷宫第I行需要访问并仅可以访问的格子数。如图中带括号红色数字就是一条符合条件的路线。 给定N，A[1..N] B[1..N]。输出一条符合条件的路线，若无解，输出NO ANSWER。（使用U，D，L，R分别表示上、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 【输入格式】 第一行是数m (n < 6 )。第二行有n个数，表示a[1]..a[n]。第三行有n个数，表示b[1]..b[n]。 【输出格式】 仅有一行。若有解则输出一条可行路线，否则输出“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.
