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)

C8051F060 自带高速AD进行数据采集 可达100兆采样率 并切缓存与片外ram 并把采集数据通过串口发送给PC ( Data Acquisition example for C8051F060 Description: This example illustrates the use of ADC1 and the DMA to acquire and store data. It is intended for use with the C8051F060 target board in the development kit. // This code measures a signal at the AIN0 input with the 16-bit SAR ADC0. // The data is sampled at a rate of 100kHz. ADC output data is transferred to XDATA memory space using the DMA. // // With the EMIF configured for off-chip XRAM access (on the upper ports), this code moves the ADC data to the C8051F060TB target boards s SRAM device. // Once data acquisition is complete, the code then prompts the user to press the P3.7 // button on the target board when ready to receive the data via the UART0 serial port. The TB features an RS-232 transceiver and connector, so the data can be transferred // to a PC via its serial port. // The code is set to acquire up to 32768 samples (for 64kbytes of data). The SRAM device - can accommodate up to 128kbytes, )
