dumbledore其中USE_STDPERIPH_DRIVER和STM32F10X_HD什么意思？
（1）USE_STDPERIPH_DRIVER
to u or not the peripheral’s drivers in application code (i.e. code will be bad on direct access to peripheral’s registers rather than drivers API) , this option is controlled by the #define USE_STDPERIPH_DRIVER
上海培训班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 */chine food
/* #define STM32F10X_MD */ /*!< STM32F10X_MD: STM32 Medium density devices */
初三数学教案/* #define STM32F10X_HD */ /*!< STM32F10X_HD: STM32 High density devices */
#define STM32F10X_CL /*!< STM32F10X_CL: STM32 Connectivity line devices */
#endif
camel toe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：
