STM32G070的CPUID地址：
1 2 3 4 5 | /*!< Device Electronic Signature */ #define PACKAGE_BASE (0x1FFF7500UL) /*!< Package data register base address */ #define UID_BASE (0x1FFF7590UL) /*!< Unique device ID register base address */ #define FLASHSIZE_BASE (0x1FFF75E0UL) /*!< Flash size data register base address */ /** |
HAL库已经预留了API可以直接读取：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | /** * @brief Returns first word of the unique device identifier (UID based on 96 bits) * @retval Device identifier */ uint32_t HAL_GetUIDw0(void) { return (READ_REG(*((uint32_t *)UID_BASE))); } /** * @brief Returns second word of the unique device identifier (UID based on 96 bits) * @retval Device identifier */ uint32_t HAL_GetUIDw1(void) { return (READ_REG(*((uint32_t *)(UID_BASE + 4U)))); } /** * @brief Returns third word of the unique device identifier (UID based on 96 bits) * @retval Device identifier */ uint32_t HAL_GetUIDw2(void) { return (READ_REG(*((uint32_t *)(UID_BASE + 8U)))); } |
