stm32f407vgt6的modbus程序，使用max485通信方式可与昆仑通态触摸屏直接通信，已调试通过。原创源码请勿转载。

编写程序定义一个vector对象，其每个元素都是指向string类型的指针，读取该vector对象，输出每个string的内容及其相应的长度。(Write a program to define a vector object, which each element is a pointer pointing to the string type, reads the vector object, the output of each string and the corresponding length.)

本作品基于matlab与vc++混合编程的一个语言信号处理平台，实现了matlab与vc++的接口通信，利用matlab强大的语言信号处理能力，再结合c++语言的强大的算法描述能力，两者取长补短，取得了很好的效果(This work is based on the matlab and vc++ mixed programming, a language signal processing platform, the matlab and vc++ interface communication, use of matlab strong language signal processing capabilities, combined with c++ language' s powerful description of the algorithm ability to both learn from each other, made good results)

串的一些基本运算，删除一段子串，置换，求s串中从start位置开始长度为len的子串等等(Some of the basic string operations, delete a substring, replacement, seeking s string starting from the start position of the sub-string of length len, etc.)

fft的c++语言实现，改自matlab的相关程序(fft c++)

用示波器测得比较标准的模拟IIC程序。STM32F103(A standard analog IIC program is measured by an oscilloscope. STM32F103)

QPSK调制解调程序，COSTA环，学习通信编程的好代码(QPSK modulation and demodulation process, COSTA ring, learning good communication programming code)

源代码包含mac802_11p.cc、mac802_11p.h、ofdm.cc、ofdm.h等一系列的代码，将其添加到NS2 可以实现对车载网的仿真

这是一段应用于opencv2.0以上版本，调用USB摄像头的源码。
