32 位基于 ARM 微控制器 STM32F101xx 与 STM32F103xx
固件函数库
UM0427 用户手册
介绍
本手册介绍了 32 位基于 ARM 微控制器 STM32F101xx 与 STM32F103xx 的固件函数库。
该函数库是一个固件函数包，它由程序、数据结构和宏组成，包括了微控制器所有外设的性能特征。该函
数库还包括每一个外设的驱动描述和应用实例。通过使用本固件函数库，无需深入掌握细节，用户也可以
轻松应用每一个外设。因此，使用本固态函数库可以大大减少用户的程序编写时间，进而降低开发成本。
每个外设驱动都由一组函数组成，这组函数覆盖了该外设所有功能。每个器件的开发都由一个通用 API
(application programming interface 应用编程界面)驱动，API 对该驱动程序的结构，函数和参数名称都进行
了标准化。
所有的驱动源代码都符合“Strict ANSI-C”标准（项目于范例文件符合扩充 ANSI-C 标准）。我们已经把驱动
源代码文档化，他们同时兼容 MISRA-C 2004 标准（根据需要，我们可以提供兼容矩阵）。由于整个固态
函数库按照“Strict ANSI-C”标准编写，它不受不同开发环境的影响。仅对话启动文件取决于开发环境。
该固态函数库通过校验所有库函数的输入值来实现实时错误检测。该动态校验提高了软件的鲁棒性。实时
检测适合于用户应用程序的开发和调试。但这会增加了成本，可以在最终应用程序代码中移去，以优化代
码大小和执行速度。想要了解更多细节，请参阅 Section 2.5。
因为该固件库是通用的，并且包括了所有外设的功能，所以应用程序代码的大小和执行速度可能不是最优
的。对大多数应用程序来说，用户可以直接使用之，对于那些在代码大小和执行速度方面有严格要求的应
用程序，该固件库驱动程序可以作为如何设置外设的一份参考资料，根据实际需求对其进行调整。
此份固件库用户手册的整体架构如下：
定义，文档约定和固态函数库规则。
固态函数库概述（包的内容，库的架构），安装指南，库使用实例。
固件库具体描述：设置架构和每个外设的函数。
STM32F101xx 和 STM32F103xx 在整个文档中被写作 STM32F101x。
