我想要具体操作的步骤，官方那个文档看完之后，真的不知道怎么操作？？？

就是把你先前用的那些文件换成新的就可以了。记住头文件和.C文件都要换。

将文件夹STM32F10xFWLib替换为STM32F10x_StdPeriph_Lib_V3.0.0\Libraries,
将文件”stm32f10x_conf.h”替换为标准外设库V3.0.0附带的最新版本,在用户把代码从旧的stm32f10x_it.c复制到新的中以后，还需要把stm32f10x_it.h替换为在标准外设库V3.0.0提供的新版本。
做了以上几步，但不行，一大堆警告D:\keil\ARM\Examples\ST\Libraries\CMSIS\Core\CM3\startup\gcc\startup_stm32f10x_hd.c(60): warning:  #1207-D: attribute "__interrupt__" ignored

startup_stm32f10x_hd.c
警告肯定有的，需要你把里面部分内容修改一下。这个都好处理，你可以加深理解。

非常感谢版主的指点

一般是更改头文件和一些设置文件

我在升级的过程中也遇到问题,编译后提示错误：
