  * @file stm32f10x.h                 ST 标准的头文件
  * @author  MCD Application Team    微控制器开发小组。
  * @version V3.5.0                              版本
  * @date 11-March-2011                   2011年3月11
  * @brief CMSIS Cortex-M3 Device Peripheral Access Layer Header File.(CMSIS：Cortex Microcontroller Software Interface Standard) 是 Cortex-M 处理器系列的与供应商无关的硬件抽象层。
  *       This file contains all the peripheral register's definitions, bits
  *       definitions and memory mapping for STM32F10x Connectivity line,
  *       High density, High density value line, Medium density,
  *       Medium density Value line, Low density, Low density Value line
  *       and XL-density devices.
  * 这个文件包含了芯片STM32F10X（接口增强型）内部的寄存器定义，位定义，内存地址变换定义，还有一些相应的高密度，低密度产品线的设备。

*       The file is the unique include file that the application programmer
  *       is using in the C source code, usually in main.c. This file contains:
  *          - Configuration section that allows to select:
  *             - The device used in the target application
  *             - To use or not the peripherals drivers in application code(i.e.
  *             code will be based on direct access to peripherals registers
  *             rather than drivers API), this option is controlled by
  *             "#define USE_STDPERIPH_DRIVER"
  *             - To change few application-specific parameters such as the HSE
  *             crystal frequency
  *          - Data structures and the address mapping for all peripherals
  *          - Peripheral's registers declarations and bits definition
  *          - Macros to access peripheral registers hardware
  *这个文件在应用程序中是至关重要的头文件，它是用C代码编写而成。通常包括在MAIN主程序中。它包括：1 设备中使用的目标应用程序。
2 决定是否使用外部设备的代码（例如使用基于寄存器的代码，而不是我们所熟悉的API应用程序接口代码）。这一设备可以通过设置 "#define USE_STDPERIPH_DRIVER" 来实现。
3  通过这一文件可以改变诸如外部设备的频率参数。
4 可以了解程序的数据结构以及外设的地址映射。
5  外设的寄存器声明和位定义可以在这个文件里面了解到。
