在keil中需添加这两个宏

一、宏USE\_STDPERIPH\_DRIVER

1.这个宏控制了是否在应用中启动外设驱动。

2.在函数Stm32f10x.h中（在keil中设置后无需在此处开启）

\#if !defined  USE\_STDPERIPH\_DRIVER  
/\*\*  
 \* @brief Comment the line below if you will not use the peripherals drivers.  
   In this case, these drivers will not be included and the application code will   
   be based on direct access to peripherals registers   
   \*/  
  /\*\#define USE\_STDPERIPH\_DRIVER\*/  
\#endif  
\#ifdef USE\_STDPERIPH\_DRIVER  
  \#include "stm32f10x\_conf.h"  
\#endif  
==》决定了是否用stm32f10x\_conf.h，此头文件中包含了各种外设的头文件，以及用于调试的assert\_param函数和assert\_failed函数（assert\_failed 自定义--发生错误时执行的操作，用于调试，但此会影响stm32运行，调试结束后，不可在用）

二、宏STM32F10X\_HD

在stm32f10x.h中

\#if !defined (STM32F10X\_LD) && !defined (STM32F10X\_LD\_VL) && !defined (STM32F10X\_MD) && !defined (STM32F10X\_MD\_VL) && !defined (STM32F10X\_HD) && !defined (STM32F10X\_HD\_VL) && !defined (STM32F10X\_XL) && !defined (STM32F10X\_CL)   
  /\* \#define STM32F10X\_LD \*/     /\*!< STM32F10X\_LD: STM32 Low density devices \*/  
  /\* \#define STM32F10X\_LD\_VL \*/  /\*!< STM32F10X\_LD\_VL: STM32 Low density Value Line devices \*/    
  /\* \#define STM32F10X\_MD \*/     /\*!< STM32F10X\_MD: STM32 Medium density devices \*/  
  /\* \#define STM32F10X\_MD\_VL \*/  /\*!< STM32F10X\_MD\_VL: STM32 Medium density Value Line devices \*/    
  /\* \#define STM32F10X\_HD \*/     /\*!< STM32F10X\_HD: STM32 High density devices \*/  
  /\* \#define STM32F10X\_HD\_VL \*/  /\*!< STM32F10X\_HD\_VL: STM32 High density value line devices \*/    
  /\* \#define STM32F10X\_XL \*/     /\*!< STM32F10X\_XL: STM32 XL-density devices \*/  
  /\* \#define STM32F10X\_CL \*/     /\*!< STM32F10X\_CL: STM32 Connectivity line devices \*/  
\#endif

这个宏根据具体的芯片来选择，与启动文件有关
