I2C

ESP8266直接接在开发板的WIFI接口，本代码为完整的程序源代码，手机装上我们提供的APP，开机就可以实现手机与开发板的WIFI链接(STM32F407ZGT6 & ESP8266 WIFI)

共5个文件。2个描述了一些时钟的初始化以及时钟的使用。2个描述了UART的使用。一个文件是一个简单的使用示例。(This zip file contains the simple code to control the stm32 components. It tells how to initialize the clock module, use the clock module, and how to do the same thing to UART.)

一维或二维卡尔曼滤波，可用于飞控系统，运动跟踪系统(One dimensional or two dimensional Calman filtering can be used in flight control system and motion tracking system.)

说明：  用stm32f10x实现can和串口通信功能(use stm32 can to usart)

RS422编程，单片机的源码RS422编程，单片机的源码，环境MDK。(RS422 programming, microcontroller source)

说明：  一份从网上获取的SX1278官方文档，手册(sx1278 office document)

For Jamp Board (ARM9 develop board from Design gateway)

基于stm32的开关电源，采用PID算法，包含整个工程！(Based on stm32 switching power supply, using PID algorithm, including the entire project!)

基于stm32f10的四轴飞行器控制程序(stm32f107 programming fly control)

说明：  三星2440 adc裸机源码，可以调试修改(S3C2440 adc source code)
