Visual C++ 串口通信编程实践 第9章和第10章源码

RS232 是异步串行通信协议，广泛应用在计算机上。异步意味着它不会有任何单独的同步时钟信号，所以它必须同步本身对传入的数据-这是通过使用开始和停止脉冲。信号本身是略有不寻常的计算机，而是作为比正常 0V 到 5V 范围、 它使用 + 12V-12V-到这做是为了提高可靠性，并极大地增加了它可以工作在可利用的范围-不需要提供此确切电压摆动和实际使用 PIC 0V 到 5V 电压摆动和几个电阻可以做一个简单的 RS232 接口，通常会很好但并不保证与所有串行端口的工作。为此我设计了串行板能使用 MAX232 芯片，这是专为 5V 的逻辑级别之间的接口设计的芯片和 + 12V /-12V 的 RS232-它生成的 + 12V /-12V 内部使用电容器充电泵，并包括四个转换器，两个传输和两个接收，只采用的每-其他两个一个串行董事会明确标记为电路如果需要可以用别的东西。

一个基于UDP的网络编程，我自己写的，希望对大家有帮助-UDP-based network programming, I wrote it myself, in the hope that everyone has to help

java编程入门文档，适合初学者，内容比较好，欢迎下载！-java programming Start document, suitable for beginners as well. Welcome download!

本程序仿真做出了一个RS编码器。运行本软件，可得到一个可视化界面，按界面提示随意输入信息序列，即可对其进行RS编码。一般的RAR解压即可-made an RS encoder. Running the software, will be a visual interface, interface suggested by the random input sequences can be encoded its RS. General RAR can extract

In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.-In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.

这是一个十分经典的异步收发器的设计，将发送和接受分开，并带有校验位，同时附赠结构图和仿真结构-This is a very classic asynchronous transceiver will be designed to send and receive separately, and with a parity bit, and comes with charts and simulation of the structure

This simple example uses the Peripheral Support libraries to provide diagnostic functionality for a HCI firmware configuration. LEDs provide status information on the number of ACL connections in use and transmit/receive events. This application does not manage any Bluetooth connections.

一个用VB编写的电话应答软件，可以进行录间和播放。使用TAPI 技术实现的，对串口编程有一定的指导作用-Using VB to prepare a telephone answering software, can be recorded and broadcast between. The use of TAPI technology and programming of serial port a certain guiding function
