一个基于串口的手机短信发送/接收程序；Demo很简单，是以异步方式读写串口的；在对话框初始化中修改串口的配置参数正确后，能100 的正常发送/接收短信(Based on the serial port of a cell phone message to send/receive process Demo is very simple, based on asynchronous serial reading and writing at initialization dialog box to modify the configuration of serial port parameters correctly, the can 100 of the normal Send/receive message)

说明：  1. 硬件接线 （1）调试串口(UART_Debug)使用UART2，在“printf.h”文件中宏定义， 对应引脚为TX-PTD7，RX-PTD6 （在“uart.h文件中宏定义）。 （2）灯0~3（LIGHT_0~LIGHT_3）对应的引脚是PTC0~PTC3，高电平点亮（由硬件接法决定） （3）SPI0_CLK对应的引脚是PTE0， SPI0_MOSI对应的引脚是PTE1， SPI0_MISO对应的引脚是PTE2，SPI0_PCS对应的引脚是PTE3， SPI1_CLK对应的引脚是PTG4， SPI1_MOSI对应的引脚是PTG5， SPI1_MISO对应的引脚是PTG6，SPI1_PCS对应的引脚是PTG7。 （4）SPI0作为master,SPI1作为slave，SPI1接收SPI0发送的数据并产生中断。 用导线将PTE0与PTG4对接，将PTE1与PTG5对接，将PTE2与PTG6对接，将PTE3与PTG7对接。(1. Hardware wiring (1) Debugging Serial Port (UART_Debug) uses UART2, macro-defined in "printf.h" file, corresponding pins are TX-PTD7, RX-PTD6. (macro definition in the uart.h file). (2) The pins corresponding to the lamp 0~3 (LIGHT_0~LIGHT_3) are PTC0~PTC3, and the high-level lighting is determined by the hardware connection. (3) The pin corresponding to SPI0_CLK is PTE0, and the pin corresponding to SPI0_MOSI is PTE1. The pin corresponding to SPI0_MISO is PTE2, and the pin corresponding to SPI0_PCS is PTE3. The pin corresponding to SPI1_CLK is PTG4, and the pin corresponding to SPI1_MOSI is PTG5. The pin corresponding to SPI1_MISO is PTG6, and the pin corresponding to SPI1_PCS is PTG7. (4) SPI0 acts as master and SPI1 acts as slave. SPI1 receives data sent by SPI0 and generates interruption. PTE0 and PTG4 are docked by wire, PTE1 and PTG5 are docked, PTE2 and PTG6 are docked, PTE3 and PTG7 are docked.)

说明：  dnn的训练及搭建源代码，非常实用，对初学者是一个不错的起点，特别是深度学习方面的(Training and building source code of DNN)

一个分形维的代码，用差分盒维计算图像的分形维值！还不错！(a fractal dimension of the code, with the difference box dimension calculations images of fractal dimension values! Also good!)

MATLAB—linear equation with one unkown(linear equation with one unkown)

深入理解指针,很详细 要搞清一个指针需要搞清指针的四方面的内容：指针的类型、指针所指向的 类型、指针的值或者叫指针所指向的内存区、指针本身所占据的内存区(the essence of pointer)
