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。(This manual introduces 32 firmware libraries based on ARM microcontroller, STM32F101xx and STM32F103xx.
The library is a firmware function package consisting of programs, data structures, and macros, including the performance characteristics of all of the microcontroller's peripherals. The library also includes driver descr iptions and application examples for each of the peripherals. By using the firmware library, you can easily apply each of the peripherals without having to dig into the details.)
