用的是时钟芯片pcf8583，可以正常显示时间,并带有有Proteus仿真，非常形象！，已通过测试。 (Is clock chip pcf8583, can properly display the time, and with Proteus simulation, the very image of , Has been tested.)

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)
