MNVETJM014

说明：  2015年电赛频率计，优点：简单易实现，精密度高(2015 frequency race frequency meter, advantages: simple and easy to implement, high precision)

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)

使用51单片机，通过BH1750获得光强值，数据处理后，使用lcd1602显示。(The light intensity value is obtained by BH1750 using 51 single chip computer. After data processing, it is displayed by lcd1602)
