STM32G0系列通过HAL库读取CPUID

STM32G070的CPUID地址：

/*!< 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：

/**

  * @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))));

}
