Stm32f1官方hal库

一、前言

进入正篇前，需要介绍一些预备知识。
St的软件开发库有两套：标准库和hal库，通常早期的开发都是使用的标准库，不过现在标准库已经停止维护了，而且新出的芯片都没有适配标准库，只有hal库。而mbed底层正是使用的hal库。
在此处我们还需要了解一点东西就是在st的标准库中，我们将芯片分为hd，md，xl等系列，而在hal库中并没有沿用这样的命名方式，而是使用xb、xe、xg等命名方式

那么相关的头文件就是

相关的启动文件就是

startup_stm32f100xb.S
startup_stm32f100xe.S
startup_stm32f101x6.S
startup_stm32f101xb.S
startup_stm32f101xe.S

startup_stm32f102xb.S
startup_stm32f103x6.S
startup_stm32f103xb.S
startup_stm32f103xe.S
startup_stm32f103xg.S
startup_stm32f105xc.S
startup_stm32f107xc.S

相关的分散文件就是

stm32f100xb.sct
stm32f100xe.sct
stm32f101x6.sct
stm32f101xb.sct
stm32f101xe.sct
stm32f102x6.sct
stm32f102xb.sct
stm32f103x6.sct
stm32f103xb.sct
stm32f103xe.sct
stm32f103xg.sct
stm32f105xc.sct
stm32f107xc.sct

由于STM32f103RB属于xb系列，而stm32f103RC属于xe系列，所以我们需要使用xe系列的文件。上面提到的有些文件有现成的可以使用，有些则需要基于stm32f103xb系列文件做适配得到。
