Description: 在STM32的I2C上摔了一跤，测试了官方提供的几个例程和库，都有不同缺陷，也无法弥补：
1、查询方式，在连续读数据的过程中不能中断
2、DMA方式类似，在同一DMA中I2C的级别必须最高，否则同1.
3、中断方式也不能有更高优先级中断I2C，否则同1.
鉴于以上原因，无奈的口线模拟了I2C。（仅仅代表个人看法，欢迎指正）
附件中的项目文件已经过测试，为感谢OUR这几年的帮助，先开源这个小程序-I2C on the STM32' s fall, the official offered few tested routines and libraries, have different defects, can not make up: 1, query methods, in a continuous process of reading the data can not be interrupted 2, DMA similar to at the same level of DMA in the I2C to be the highest, or with 1.3, can not interrupt higher priority interrupt I2C, or with 1. For these reasons, but unfortunately the port line to simulate the I2C. (Only represent my personal views, please correct me) the attached project document has been tested and OUR for the past few years thanks to help, first open the applet Platform: |

Description: 该文件是RT-Thread STM32的工程模板。
各目录说明如下：
1. Applications：应用文档
- 包含了main文件, 中断处理文件, 系统配置文件
2. Compiler：编译器文档
- 目前提供了 RealView MDK 的工程模板
3. Documents：文档说明，
- 提供模板使用教程
- 提供了模板版本说明
- 提供了模板分层说明，请重点阅读！！！
- 提供 doxygen 注释风格的模板，说明，软件
4. Drivers：PCB板级驱动文档
- 如按键、EEPROM、模拟I2C等等
- 该层要能对上屏蔽掉最底层 Libraries
这样起到承上启下的作用,方便跨平台移植
5. Libraries：MCU外设库文档
- 此部分由芯片厂商提供，是标准库
- 用户不得修改此层
6. Modules：组件层文档
- 按大功能划分的软件组件。如UI组件、网络通信组件、文件系统组件
- 不建议直接调用最底层 Libraries
7. OS：操作系统文档
- 提供 RT-Thread V0.3.3 系统-This file is the template of RT-Thread the STM32 engineering.
Each directory is as follows:
Applications: Application document
- Contains the main file, interrupt handling files, system configuration files
Compiler,: Compiler documentation
- The current RealView MDK project templates
3 Documents: Document Description
- Provide a template using the tutorial
- Provides a template Imprint
- Provides a template hierarchical description, please focus on reading! ! !
- Doxygen comment style template, instructions, software
4 Drivers: PCB board-level driver documentation
- Such as buttons, EEPROM, analog I2C, etc.
- The layer on a masked the bottom of Libraries
So play a connecting role to facilitate cross-platform portability
Libraries: MCU peripherals library documentation
- This section provided by the chip manufacturer, the standard library
- User may not modify this layer
Modules: component layer document
