基于Linux下的pwm驱动测试程序，可根据自己的需要修改设备节点。(This is a pwm drivers test procedure based on Linux，you can modify device nodes according to your needs.)

实现简单的数据传输,可以传送字符形式的数据,分为服务器和客户端(For simple data transfer, you can transfer data in the form of characters, divided into servers and clients)

QT creator 编的串口C++上位机程序(QT creator series of serial C++ PC program)

串口输出：LED_KEP test!； 程序运行后8LED会数字滚动，LED跑马，然后按键盘8LED会显示不同的键值； 屏幕上显示相关的文字。(Serial port output: LED_KEP test!; After the program runs, the 8LED will scroll digitally, the LED will run horse, and then the keypad 8LED will display different keys. The relevant text is displayed on the screen.)

在linux平台下,纯c写的盲信号分离的代码.它采用基于卷积混合的盲信号分离算法,不但可以分离人工合成的混合信号,而且对于真实环境中的卷积混合的语音信号也能够分离.在本程序中,包含了两个测试文件,makefile后便可以直接使用. 另外值得一提的是,压缩包里包含有一些语音处理方面的常用函数.例如fft变换,读取写入wav文件,以及一些常用的一维向量和二维矩阵变换的函数.这些可以直接应用在其他应用程序里去.(Linux platform, the blind signal separation of pure c write code. Blind signal separation algorithm based on convolution mixed, can be separated not only synthetic mixed-signal and voice signal convolution mixed in real environment can separation in the program, contains two test files can directly use the makefile after. Also worth mentioning is that the compressed bundle includes voice processing commonly used functions such as fft transform read write wav file, as well as some of the commonly used one-dimensional vector and two-dimensional matrix transform function. these can be applied directly into other applications.)

it is CASTALIA source in linux

分析嵌入式linux中telnet服务器的实现(analysis for telnet server in embeded linux.)

《嵌入式Linux应用程序开发详解》 写得不错的一本书，比较适合嵌入式Linux的入门人员学习，一步一步把你引入Linux的世界（比较针对嵌入式Linux开发的初学者，若想从头学习完整的Linux操作系统，可选择《鸟哥的Linux私房菜》这本书）。(" Embedded Linux application development detailed a well-written book, more suitable for embedded Linux Getting Started to learn, step by step, you introduce the world of Linux (compare for beginners embedded Linux development, if you want to start from scratch learning complete Linux operating system, select " Just Linux private kitchens" in this book).)

如果您刚接触嵌入式开发，那么大量可用的引导装载程序（bootloader）、规模缩小的分发版（distribution）、文件系统和 GUI 看起来可能太多了。但是这些丰富的选项实际上是一种恩赐，允许您调整开发或用户环境以完全符合您的需要。对 Linux 嵌入式开发的概述将帮助您理解所有这些选项。(Embedded fourth year of development, so much available bootloader (Bootloader). smaller scale version of the distribution (distribution), file system and GUI may seem too much. But these rich options is a gift, allows you to adjust the development or user environment to meet your needs. Embedded Linux for the development of the outline will help you understand all these options.)
