比如说下面的第一个SR 寄存器定义,它只是定义了SR但是没有定义SR的值,那使用时怎么知道SR的地址是哪个???
typedef struct
{
__IO uint32_t SR; /*!< ADC status register, Address offset: 0x00 */
__IO uint32_t CR1; /*!< ADC control register 1, Address offset: 0x04 */
__IO uint32_t CR2; /*!< ADC control register 2, Address offset: 0x08 */
__IO uint32_t SMPR1; /*!< ADC sample time register 1, Address offset: 0x0C */
__IO uint32_t SMPR2; /*!< ADC sample time register 2, Address offset: 0x10 */
__IO uint32_t JOFR1; /*!< ADC injected channel data offset register 1, Address offset: 0x14 */
__IO uint32_t JOFR2; /*!< ADC injected channel data offset register 2, Address offset: 0x18 */
__IO uint32_t JOFR3; /*!< ADC injected channel data offset register 3, Address offset: 0x1C */
__IO uint32_t JOFR4; /*!< ADC injected channel data offset register 4, Address offset: 0x20 */
__IO uint32_t HTR; /*!< ADC watchdog higher threshold register, Address offset: 0x24 */
__IO uint32_t LTR; /*!< ADC watchdog lower threshold register, Address offset: 0x28 */
__IO uint32_t SQR1; /*!< ADC regular sequence register 1, Address offset: 0x2C */
__IO uint32_t SQR2; /*!< ADC regular sequence register 2, Address offset: 0x30 */
__IO uint32_t SQR3; /*!< ADC regular sequence register 3, Address offset: 0x34 */
__IO uint32_t JSQR; /*!< ADC injected sequence register, Address offset: 0x38*/
__IO uint32_t JDR1; /*!< ADC injected data register 1, Address offset: 0x3C */
__IO uint32_t JDR2; /*!< ADC injected data register 2, Address offset: 0x40 */
__IO uint32_t JDR3; /*!< ADC injected data register 3, Address offset: 0x44 */
__IO uint32_t JDR4; /*!< ADC injected data register 4, Address offset: 0x48 */
__IO uint32_t DR; /*!< ADC regular data register, Address offset: 0x4C */
} ADC_TypeDef;

封装在一个结构体里面了啊,你要用就直接对结构体成员进行操作就好啦
