STM32头文件的选择

jiaozhu

估计有很多人跟我一样，不是很清楚头文件的选择，下面将有一个很详细的介绍。

#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
/*  Tip: To avoid modifying this file each time you need to switch between these
        devices, you can define the device in your toolchain compiler preprocessor.

 - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers
   where the Flash memory density ranges between 16 and 32 Kbytes.
 - Low-density value line devices are STM32F100xx microcontrollers where the Flash
   memory density ranges between 16 and 32 Kbytes.
 - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers
   where the Flash memory density ranges between 64 and 128 Kbytes.
 - Medium-density value line devices are STM32F100xx microcontrollers where the
   Flash memory density ranges between 64 and 128 Kbytes.  
 - High-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 256 and 512 Kbytes.
 - High-density value line devices are STM32F100xx microcontrollers where the
   Flash memory density ranges between 256 and 512 Kbytes.  
 - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 512 and 1024 Kbytes.
 - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.

应该是启动文件吧。。。。

回复【3楼】xiaoyan:
---------------------------------
不是  启动文件应该是startup文件，不过与启动文件的选择有点关系
