STM32F407信号发生器输入一个正弦波，AD采样，DA输出，系统频率应该是输入的波形的频率的10倍以上保证输出波形的完整性，系统的输出频率可以使用示波器测试出。(Stm32f407 signal generator input a sine wave, AD sampling, Da output and system frequency should is 10 times the frequency of the input waveform to guarantee that the above output waveform of integrity, the output frequency of the system can use oscilloscope to test out. )

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)
