haar小波分析的类，只有头文件，输入为一个序列的信号，输出为haar小波分解后的各级参数(haar wavelet class)

STM32 IAP官方源码程序，Ymodem 发送 接收。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。

PCB工艺介绍以及规范，里面内容非常详细，虽然资料是13年的，但是很实用。(PCB technology introduction and specification, content is very detailed, although the information is 13 years, but very practical.)

说明：  基于正点原子stm32精英开发板和openmv通讯，含openmv端配置，通过openmv（usart3）输出端连接到开发板（usart1）接收端，再由开发板（usart1）输出端输出到电脑，可以用xcom看到(Based on the communication between STM32 elite development board and openmv, including the configuration of openmv terminal, it is connected to the receiving end of development board (usart1) through the output end of openmv (usart3), and then output to the computer by the output end of usart1, which can be seen by XCOM)

此程序避免了对于大学期间的学生登记注册功能(This procedure avoids the college students for the registration function)

本程序是关于文件的操作源码，用于像ini文件中写入数据(This program is operating on the source file for write data as the ini file)

计算空间几何距离的MATLAB计算机算法(Spatial geometric distance calculation algorithm MATLAB computer)

说明：  C8051F USB MASS STORAGE example code

说明：  使用libsvm进行三分类，svm多分类可以类似编程(Use libsvm for three categories, svm classification can be more similar to programming)
