stm32中#define GPIO_Pin_0 ((u16)0x0001) /* Pin 0 selected

stm32中#define GPIO_Pin_0 ((u16)0x0001) /* Pin 0 selected stm32中#define LCD_cs(x) x GPIO_SetBits(GPIOB,LCD_CS) :GPIO_ResetBits(GPIOB,LCD_CS) 宏定义,stm32中#define GPIO_Pin_0 ((u16)0x0001) /* Pin 0 selected */为什么后面要加括号（外面那个括号）? STM32 stm32中重映像是什么意思? stm32中使用的这个 STM32 疑惑,#ifdef _TIM2#define TIM2 ((TIM_TypeDef *) TIM2_BASE)#endif /*_TIM2 */#ifdef _TIM2EXT TIM_TypeDef *TIM2;#endif /*_TIM2 */ Stm32中宏定义是什么意思呢#ifndef DEBUG#ifdef _TIM2#define TIM2 ((TIM_TypeDef *) TIM2_BASE)#endif /*_TIM2 */typedef struct{vu16 CR1;u16 RESERVED0;vu16 CR2;u16 RESERVED1;vu16 SMCR;u16 RESERVED2;vu16 DIER;u16 RESERVED3;vu16 SR;u16 RESERVED4;vu stm32中如何进行位定义 stm32中如何测量脉冲个数 STM32中 TIM_EncoderInterfaceConfig()函数有什么作用?
