1．集成计数器、译码器或数据选择器、逻辑门、数码管、开关等分立元件若干； 2．+5V电源一个； (1. Integrated counter, decoder or data selector, logic gates, digital control, a number of discrete components, such as switches 2.+5 V supply one )

基于周立功CAN的上位机软件，可以实现对CAN的打开，波特率设置，滤波设置，消息发送，消息接受等等。亲测可用。完全可以作为二次开发的资料。(Based ZLG CAN PC software can be achieved on the open CAN baud rate settings, filter settings, the message is sent, the message to accept more. Pro-test available. Can be used as secondary development information.)

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)

说明：  基于stm32固件库的跑马灯范例，供参考(An Example of Racing Horse Lamp Based on STM32 Firmware Library)
