说明：  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.)

qt的一些基本源代码，以及一些参考资料。还有一些其它说明(demo for qt)

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.)

此代码为由QT开发的界面切换，可以实现从登陆界面切换到其他界面的功能(Development of this code grounds QT interface switching, can switch from the login screen to the other interface functions)

这是linux登陆时候的一小程序,主要功能实现了用户登陆时,只能执行我们定义的一些命令.其他对用户不可见.(This is the time of landing a small program, the main function of user landing, they can only enforce our definition of order. Other users can see.)

说明：  选用ZYNQ SoC作为智能相机系统的硬件处理平台，依据系统设计需求，将系统整体功能结构的开发划分到用户空间、内核空间、底层硬件三个层面。在硬件层，对系统硬件功能进行了模块化设计，分别对基于USB和OV7725的双通道图像采集模块、HDMI显示模块进行开发。(Zynq SOC is selected as the hardware processing platform of the intelligent camera system. According to the system design requirements, the development of the overall functional structure of the system is divided into three levels: user space, kernel space and bottom hardware. In the hardware layer, the hardware functions of the system are modularized, and the dual channel image acquisition module and HDMI display module based on USB and ov7725 are developed respectively.)

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.)

《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.)
