问，编译usart.c无法连接，怎么改？ 错误提示及源码文件都粘贴如下：

如上错误怎么改？  注明不能使用stm32f10x.h这个库， 因为使用这个库我的工程里头好多函数都要改

stm3201

回复【4楼】augustedward:
---------------------------------
改成這样子就可以了：
#include "stm32f10x_gpio.h"
#include "stm32f10x_usart.h"
#include "misc.h"
#include "stm32f10x_rcc.h"
#include "stdio.h"
因为3.50以上的nvic不在有专门 stm32f10x_nvic.h来写了，而是放在了misc.h中，所以包含 misc.h就可以了

八度空间

是不是没添加stm32f10x_usart.h头文件

stm3201

回复【2楼】Badu_Space:
---------------------------------
加了， 看我上面的头文件源码，里头什么都加了
usart.h文件：
#ifndef __USART_H
#define __USART_H

//#include "stm32f10x_lib.h"
// #include "stm32f10x.h"
#include "stm32f10x_gpio.h"
#include "stm32f10x_usart.h"
#include "stm32f10x_nvic.h"
#include "stm32f10x_rcc.h"
//////////////////////////////////////////////////////////////////////////////////

augustedward

//#include "stm32f10x_lib.h" 
#include "stm32f10x.h" 
#include "stm32f10x_gpio.h" 
#include "stm32f10x_usart.h" 
#include "stm32f10x_nvic.h" 
#include "stm32f10x_rcc.h" 
这样改试试
