网络聊天用VC编写的，还不错哦！

本文主要阐述了DTMF的原理及如何在MATLAB上产生DTMF信号，主要涉及到电话拨号音合成的基本原理及识别的主要方法，利用 MATLAB 软件以及 FFT 算法实现对电话通信系统中拨号音的合成与识别。并进一步利用 MATLAB 中的图形用户界面 GUI 制作简单直观的模拟界面。 能够利用矩阵不同的基频合成 0 － 9 不同按键的拨号音，并能够对不同的拨号音加以正确的识别，实现由拨号音解析出电话号码的过程，完成对电话拨号音系统的简单的实验仿真。-This paper described the principle and how DTMF in MATLAB to generate DTMF signals, mainly related to the telephone dial tone of the basic principles of synthesis and identification of the main methods, the use of MATLAB software and the FFT algorithm on the telephone communication system dial tone Synthesis and Recognition . And further the use of MATLAB in the production of graphical user interface simple and intuitive GUI interface simulation. Able to take advantage of matrix synthesis of different fundamental frequency 0- 9 different keys of the dial tone and be able to different dial tone to be the correct identification, the dial tone from a telephone number to resolve the process of completion of the telephone dial tone system, a simple experiment simulation

基于手机平台的人脸识别系统设计，很前沿的东西。值得珍藏-Mobile phone platform based on face recognition system design, it is the forefront of things. Worthy of collection

Abstract: By using gateway systems on large 32-bit platforms, networks of small, 8- and 16-bit microcontrollers can be monitored and controlled over the Internet. With embedded Linux, these gateways are easily moved from full-blown host PCs to embedded platforms like the PC104. In this class you will learn about hardware platforms that support embedded Linux, Linux kernel configuration, feature selection, installation, booting and tuning.

fd_set参数：一个用于检查可读性（readfds），一个用于检查可写性（writefds），另一个用于例外数据（exceptfds）。从根本上说， fd_set数据类型代表着一系列特定套接字的集合-fd_set parameters : a check for readability (readfds) one could write a check for (writefds) Another exception for the data (exceptfds). Fundamentally speaking, fd_set data types represent the range of specific set of socket

用delphi做的，用来模拟can主控节点测试分模块节点的测试程序-used to do, used to simulate the control nodes can test-node module testing procedures

云台解码器派尔高D协议，已经包含所有命令，想对来说一般都能看的懂，无特别之处，此版本非变异版本，属于原版！-PTZ decoder Pelco D protocol, already contains all the orders, would like to look for the knowledge generally available and no special feature of this version of non-variant version, belongs to the original!

资源描述 平台：windows或linux 语言：python、opencv 功能：可实现windows平台或Linux平台下，在本地计算机拍照，可在局域网内的一台计算机上显示图片。 流程：1、运行server.py          2、运行video.py          3、运行client.py

uwb_ppm_bpsk的源码,可以由此学习UWB的调制解调方式,对研究UWB有很大帮助-uwb_ppm_bpsk source code, which can study the UWB modulation and demodulation, UWB research will be of great help

可以自己设置读取路径，也可以使用默认的路径，界面比较友好，在用户输入指令错误的情况下会自动提示重新输入，可以根据中文查找，可以添加和删除内容，还可以修改指定的内容，总之功能还算比较强大吧，更加重要的是能够识别电话号码，唯一美中不足的是没有能够自动识别电子邮件地址的格式，相信高手一定能够帮我完善这样一个功能啊！（我已经把那个源文本文件包含进去了，大概的格式就是那样，大家要更改内容就按照我给的那个文件更改，输出结果支持自动对齐）
