IAR编译器中STM32F10X_XX宏定义的选择

             IAR编译器中STM32F10X_XX宏定义的选择


其中USE_STDPERIPH_DRIVER和STM32F10X_HD什么意思?

(1)USE_STDPERIPH_DRIVER 

to use or not the peripheral’s drivers in application code (i.e. code will be based on direct access to peripheral’s registers rather than drivers API) , this option is controlled by the #define USE_STDPERIPH_DRIVER

即这个定义控制了是否在应用中启用外设驱动。我们使用标准外设库本来就为了方便控制外设,所以要添加这个定义,以启用外设驱动。

(2)STM32F10X_HD

     如果你使用stm32f10x_stdperiph_lib,会发现在stm32f10x.h文件会有一段关于宏选择的代码,如:

#if !defined (STM32F10X_LD) && !defined (STM32F10X_MD) && !defined (STM32F10X_HD) && !defined (STM32F10X_CL)  
  /* #define STM32F10X_LD */   /*!< STM32F10X_LD: STM32 Low density devices */  
  /* #define STM32F10X_MD */   /*!< STM32F10X_MD: STM32 Medium density devices */  
  /* #define STM32F10X_HD */   /*!< STM32F10X_HD: STM32 High density devices */  
  #define STM32F10X_CL    /*!< STM32F10X_CL: STM32 Connectivity line devices */  
#endif  

 

    至于要使用哪个宏,则需要根据具体的芯片来进行选择。如果是STM32F105xx和STM32F107xx,是Connectivity Line Devices,则宏定义选择的是STM32F10X_CL;如果是别的型号,则根据FLASH的容量来进行选择。可能文字写的有点不太清楚,还是以表格来说明:

MCU 型号

FLASH大小

STM32F10X_LD

STM32F101xx

STM32F102xx

STM32F103xx

16 ~ 32 Kbytes

STM32F10X_MD

STM32F101xx

STM32F102xx

STM32F103xx

64 ~ 128 Kbytes

STM32F10X_HD

STM32F101xx

STM32F103xx

256 ~ 512 Kbytes

STM32F10X_CL

STM32F105xx

STM32F107xx

忽略
