贪婪算法

开关磁阻电机的仿真模型，主要涉及是电流斩波控制，里面模型是MATLAB自带(a simulation model of switched reluctance motor，mainly about current chopping control)

在51 单片机控制下，控制64 个LED灯做流星灯旋转，已量产的程序，可以使用。。(51 MCU control, control 64 LED lights do the meteor light rotation, production program, you can use. .)

主要实现功能： 1 tcp server并发（主要涉及文件app_lwip.c、app_tcp_server.c） 2 网线热插拔（主要涉及文件app_lwip.c、app_tcp_server.c） 3 不重启修改ip地址（主要涉及文件app_lwip.c、app_tcp_server.c、app_key.c（按键修改ip地址）） 4 将lwip的数据接收从中断方式改成单独的接收任务方式（主要涉及文件app_lwip.c） 5 usb串口信息打印（115200波特率） 6 注意：使用的stm32的HAL库而不是标准库(The main functions are: 1 TCP server concurrency (mainly related to file app_lwip.c, app_tcp_server.c) Hot plugging of 2 network lines (mainly related to documents app_lwip.c, app_tcp_server.c) 3 do not reset the IP address (mainly related to file app_lwip.c, app_tcp_server.c, app_key.c (key modify IP address)) 4 change the data reception of LwIP from the interrupt mode to the individual receiving task (mainly involving the file app_lwip.c) 5 USB serial port information printing (115200 baud rate) 6 note: the HAL Library of the STM32 used instead of the standard library)

说明：  sh-1的加密解密算法的实现，有相关文件和代码(sh-1 encryption and decryption algorithm, related documents and code)

说明：  just to active my account sss

因为是windows服务 所以最后要手动安装一下这个服务程序，在cmd窗口输入命令：InstallUnit BackupFileService.exe。

说明：  国产ARM芯片，GD32F103系列，替代STM32F103系列，I2C采集项目，编译即可通过，多支持国产芯片。(Domestic ARM chip, gd32f103 series, replace STM32F103 series, I2C acquisition project, compile can pass, support domestic chips.)

一个很好很好的文档。一个不错的文档。(A very, very good documentation. A documentation that is useful.)
