介绍了一种构建在定点DSP上的高速瑞利衰落信道仿真模型。通过应用确知性瑞利过程的理论，使得仅需要较少的低频正弦波分量以及简单的运算即可实现较高精度的信道建模；进而可采用查表法并结合TMS320C6202定点数字信号处理器的高并行性和处理能力构造高速的仿真模型-Construction of a fixed-point DSP in the high-speed Rayleigh fading channel simulation model. Through the application process unascertained Rayleigh theory, only need to make small low-frequency sine wave components and the simple operation can achieve higher accuracy Channel modeling; then use look-up table method and combination TMS320C6202 fixed-point digital signal processor parallel and can handle Construction of the high-speed simulation model

一个封装很好的串口类。是基于MFC的 。想编写rs 232串口编程，可应用此类。-a good serial category. Based on the MFC. Rs 232 to prepare serial programming, such application.

NRF2401无线模块，STM32程序实现了数据双向通信.它分为接收和发送两部分，发送时发送的源程序，接收是接收的源程序，分别设置了俩个文件夹。nrf24l01在stm32的模块上，通过spi接口连接，实行通信，最终实现两块单独的stm32模块实现短距离的无线通信，速度高，功耗小。

使用softAP实现多方聊天通讯的例子源码，首先把多部手机连接到一个局域网中，在一个手机上安装服务端，然后服务端会自动显示一个可访问的IP地址并等待客户端连接，在其他手机上安装客户端，输入服务端显示的IP地址点击连接就可以与服务端进行连接，不需要改动源码里面的任何东西，亲测有效。
