Digital-loop-display

这是一个用于工控的上位机系统，可以实时监测温度，露点，湿度。用户可以根据具体情况设定报警点，当达到报警点，系统通过邮件发送报警信息给用户。(This is a PC for industrial control of the system, can be real-time monitoring of temperature, dew point and humidity. Users can set alarms based on specific circumstances, when the police reached, the system, through e-mail warning messages to users.)

Visual C++数据库编程与实例 pdf超高清电子版与原书光盘，非常不容易搞来的，福利来啦！200多M，只能分割，敬请见谅！主卷是VisualCDatabaseProgramAndExamples.zip，还需要下载12个分卷，此为第5分卷(Visual C++ database programming with examples pdf electronic version of ultra-high-definition optical disc with the original book, is not easy to engage in, and benefit coming! More than 200 M, only split, please forgive me!)

基于STM32F4的四轴航拍平台。以STM32F407为控制核心，四轴飞行器为载体，辅以云台的航拍系统。硬件上由飞控电路，电源管理，通信模块，动力系统，机架，云台伺服系统组成。算法上采用简洁稳定的四元数加互补滤波作为姿态解算算法，PID作为控制器，实现飞行，云台增稳等功能(Four axis aerial platform based on STM32F4. Taking STM32F407 as the control core, the four axis flying vehicle as the carrier, and the aerial camera system with ptz. The hardware is composed of flight control circuit, power management module, communication module, power system, frame and PTZ servo system. The algorithm uses a simple and stable four yuan number plus complementary filtering as the attitude calculation algorithm, and PID is used as a controller to achieve flight, PTZ stability, and other functions)
