一个集成了 BMP085 GP2Y1010 nrf2401 以及DHT11的以stm32f4 位控制核心的，天气预测程序！(An integrated BMP085 GP2Y1010 nrf2401 and DHT11 to stm32f4 bit control core, weather forecasting program!)

飞思卡尔9s12XET用PWM控制蜂鸣器(Freescale 9s12XET with PWM control buzzer)

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)

本包是汤竞南版的51单片机c语言开发与实例，其中包括pdf版的书，和对应书中源码例子，对学习c51开发的初学者很有用。(This package is a version of the 51 Southern Tang King SCM c language and examples, including the pdf version of the book, the book and the corresponding source code examples for beginners learning c51 develop useful.)
