stm32官方库数据格式定义 uint16_t

STM32里的类型定义，见如下说明：

typedef volatile unsigned short vu16;

typedef __IO uint16_t  vu16 

/* IO definitions (access restrictions to peripheral registers) */

#ifdef __cplusplus

  #define   __I     volatile             /*!< defines 'read only' permissions                 */

#else

  #define   __I     volatile const       /*!< defines 'read only' permissions                 */

#endif

#define     __O     volatile             /*!< defines 'write only' permissions                */

#define     __IO    volatile             /*!< defines 'read / write' permissions              */
