昨晚在github发现了一个老外自己整理的封装库，有很多，比如一些通讯啊啥的，一些显示屏驱动等等

STM32F4

Libraries and projects

Here are listed all libraries for STM32F4 devices.Libraries are designed to work with STM32F4xx series of MCU. Every project hereis created with Keil uVision, but tested with GCC compiler too (Coocox). Eachproject includes 4 targets:

1. STM32F429-Discovery board (STM32F429ZI, 180MHz)

2. STM32F4-Discovery board (STM32F407VG, 168MHz)

3. STM32F401-Discovery (STM32F401, 84MHz)

4. STM32F411C-Discovery (STM32F411, 100MHz)

5. Nucleo F411-RE (STM32F411RE, 100MHz)

6. Nucleo F401-RE (STM32F401RE, 84MHz)

7. STM32F446xx (180MHz)

8. STM32439-Eval (STM32F439NI, 180MHz)

When you download repository and open project, you haveto set correct your target, for device you use. If you use other device in yourproject, then set your project and copy settings there from target options.

来看看真正的东西吧~~~激动

随意show两个代码：

（GPIO）

（IIC）

老外写的很是完善，英文的注释就连小编这种英语渣渣都能简单易懂，能直接用，不用怎么配置了，当然可以改装成为我们自己习惯的库。

虽然st的库很完善，但是以后我们写代码都可以有自己的库，拿来即用，很是方便。
