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

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。
