《ARM嵌入式Linux系统开发技术详解》，该书由浅入深、通俗易懂地讲解了嵌入式Linux的系统设计与开发。全书共25章，从嵌入式处理器ARM开始，讲解了ARM处理器的资源、ARM的指令集、ADS开发工具、嵌入式系统硬件环境的构建、Boot Loader、Linux内核移植、嵌入式文件系统、嵌入式Linux多任务程序开发、嵌入式Linux设备驱动开发、嵌入式Linux网络程序开发、MiniGUI图形界面开发、设备驱动开发案例、综合案例等内容。书中通过大量的例程来讲解知识要点，并提供了大量极有参考价值的开发案例，读者可以通过这些例程和开发案例对嵌入式Linux开发有一个系统的学习和提高。 (" ARM embedded Linux system development techniques explain," the book easy-to-digest, easy to understand and explain the embedded Linux system design and development.)

How to Program the Casio QT6000 cash register and usage

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.)

DL/T645-97协议发送代码实例，这个部分能够通过串口接收和发送645协议包。(DL/T645-97 file send code)

本手册从获取内核源码开始,一步一步的讲解一个完整的内核的移植,使读者最终可以配置、移植、 裁剪内核,编写驱动程序,从而掌握整个嵌入式 Linux 系统的开发方法。 (This manual access to the kernel source code from the beginning, step by step explain the migration of a complete core, so that the reader could eventually configuration, migration, cutting the kernel, write drivers, so as to equip the entire embedded Linux system development methodology.)

用以测试Linux下的无线网络测试命令，静态编译，可以直接使用，改动均可见。(These tools was used for testing wifi in Linux system，and it has been compiled in static。Beside, you can find how to modify。)

说明：  利用Qt开发的仓库管理系统，包含数据库操作，实现出入库和库存查看等功能(The warehouse management system developed by Qt includes database operation, access to warehouse and inventory view functions.)

TQ2440开发板验证程序，例子很多很实用！(TQ2440 development board verification process, many examples of very practical!)

The QScriptStdMessageHandler class implements a message handler that writes to standard output for Linux.
