比较常见的问题
当软件复杂包含的各种组件多了就可能出这个
先理解提示，明显是什么原因
\libaraies\CMSIS\stm32f10x.h(511): error: #256: invalid redeclaration of type name "uint32_t" (declared at line 64 of "C:\Keil_v5\ARM\ARMCC\Bin..\include\stdint.h")
意思是说uint32_t 出现了两处定义，编译器不知道该用哪个，所以报错
你分别找到这两处定义，在stm32f10x.h 511行，和stdint.h里
写这标准的.h文件的人都是很专业的，他们会考虑到可能出现的问题，所以你在至少其中一处能看到
#ifndef uint32_t
或者类似的对uint32_t 进行预判断的宏定义，假设是在stm32f10x.h文件
那么你的各种C文件里
#include <stdint.h>
#include <stm32f10x.h>
包含的顺序就必须stdint.h在前面
