我用的处理器是
STM32F107VCT6
在stm32f10x.h文件中看到如下内容:
#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_CL */ /*!< STM32F10X_CL: STM32 Connec
tivity 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.
按照Tip的描述,在Preprocessor symbol中添加了STM32F10X_CL
工程编译没有问题,但是发现把STM32F10X_CL去掉,编译也没有问题
按照stm32f10x.h中的描述,编译应该会抱错啊
#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)
#error "Please select first the target STM32F10x device used in your application (in stm32f10x.h file)"
#endif
请问为什么在Preprocessor symbol中不添加STM32F10X_CL也不会抱错呢?
