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：  基于无人机，组合导航实现联邦滤波器。代码(UAV-based, integrated navigation filter to achieve Federation. Code)

说明：  MSP430红外解码驱动，占用了一个定时器资源。(MSP430 IR decoding drive, taking up a timer resources.)

Radar simulation in visual c++

stm32下跑通usb外设，编译环境基于keil(stm32 next run through usb peripherals, based on keil compiler environment)

说明：  51单片机控制GSM模块发短信和打电话的C源码(GSM single-chip control module 51 send text messages and phone calls the C source)

该C语言例程为AM波，DSB波调幅程序，适用于单片机等等。(The C language routines for the AM wave, DSB wave amplitude modulation procedures, for single-chip and so on.)

中英文电子词典，可以联网和在线进行翻译。(English electronic dictionary, can be networked and online.)

单片机c程序集(伟福）,环境为LAB6000，包含所有实验的程序，并附有详细的注释，难得的好资料，网上很难找。(Singlechip c assembly (Fu Wei), the environment LAB6000, contains all the experimental procedure, together with detailed notes, rare good information hard to find online.)
