关于keil编译的问题

巫妖

我按照原子的教程，自己新建了一个F4的工程文件，但编译的时候出现两个stm32f4xx.h,导致编译不通过，很多定义重复了


但我USER文件下只有一个stm32f4xx.h，我也试过原子自带教程的工程文件，编译没有问题，能够通过。

肯定是我哪里没设置对出现的问题，我试着打开过这两个头文件，应该是同一个.h，请教一下谁遇到过这个问题

错误提示是什么

我查过这些错误，都是在stm32f4xx.h头文件里定义命名的

添加了stm32f4xx_fmc.c这个文件没

巫妖

qiuzhicheng 发表于 2018-9-5 17:05添加了stm32f4xx_fmc.c这个文件没

添加了，都是照搬的工程文件。而且stm32f4xx_fmc.h里面也有stm32f4xx.h.其他.c里都只有一个stm32f4xx.h，就main.c里有两个，莫名其妙啊

qiuzhicheng

发你工程看一下

ytc

FMC必须去掉，头文件引入是不是重复了

Soux

我也是一样的问题。选择Manage Project Items，往group里添加文件的时候，FWLIB的stm32f4xx_fmc.c 要删掉

stm32f4xx_fmc.c编译报错的真正原因并不是头文件重复包含或者工程只定义了STM32F40_41xxx宏，而是stm32f4xx.h中FMC_R_BASE和FSMC_R_BASE的基地址数值相等造成的，理由如下：
1.工程中同样添加了STM32F40_41xxx系列器件没有的其他外设驱动c文件，编译时并没有报错
2.头文件包含没有问题，报错的宏已经在stm32f4xx.h中条件定义过

至于为什么会这样我猜测可能和arm编译器具体的编译规则有关，可能同一个地址编译出两个命名不同的外设模块是不被允许的
