? ???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。那么,这些宏又对应着哪些具体的芯片呢?其实我们可以在《Reference manual》的第九章中找到答案,如文档截图:

? ? 这段话的意思很明显,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:
宏 |
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 |
? ? 这些参数,和MDK的设备参数一致,如图所示:
