STM32⾥的类型定义，见如下说明：
/* Exported types ------------------------------------------------------------*/
typedef signed long s32;
typedef signed short s16;
typedef signed char s8;
typedef signed long const sc32; /* Read Only */
typedef signed short const sc16; /* Read Only */
typedef signed char const sc8; /* Read Only */
typedef volatile signed long vs32;
typedef volatile signed short vs16;
typedef volatile signed char vs8;
typedef volatile signed long const vsc32; /* Read Only */
typedef volatile signed short const vsc16; /* Read Only */
typedef volatile signed char const vsc8; /* Read Only */
typedef unsigned long u32;
typedef unsigned short u16;
typedef unsigned char u8;
typedef unsigned long const uc32; /* Read Only */
typedef unsigned short const uc16; /* Read Only */
typedef unsigned char const uc8; /* Read Only */
typedef volatile unsigned long vu32;
typedef volatile unsigned short vu16;
typedef volatile unsigned char vu8;
typedef volatile unsigned long const vuc32; /* Read Only */
typedef volatile unsigned short const vuc16; /* Read Only */
typedef volatile unsigned char const vuc8; /* Read Only */ Exported_types
类型定义
typedef int32_t s32
typedef int16_t s16
typedef int8_t s8
typedef const int32_t sc32
typedef const int16_t sc16
typedef const int8_t sc8
typedef __IO int32_t vs32
typedef __IO int16_t vs16
typedef __IO int8_t vs8
typedef __I int32_t vsc32
typedef __I int16_t vsc16
typedef __I int8_t vsc8
typedef uint32_t u32
typedef uint16_t u16
typedef uint8_t u8
typedef const uint32_t uc32
typedef const uint16_t uc16
typedef const uint8_t uc8
typedef __IO uint32_t vu32
types是什么意思
typedef __IO uint16_t vu16
typedef __IO uint8_t vu8
typedef __I uint32_t vuc32
typedef __I uint16_t vuc16
typedef __I uint8_t vuc8
所以，前⾯三者依次与后者等价，即：
typedef uint32_t u32
typedef uint16_t u16
typedef uint8_t u8
所述。
