ST中关于变量的定义都在一个独立的stdint.h中，关于变量的定义如下
- /* exact-width signed integer types */
- typedef signed char int8_t;
- typedef signed short int int16_t;
- typedef signed int int32_t;
- typedef signed __int64 int64_t;
- /* exact-width unsigned integer types */
- typedef unsigned char uint8_t;
- typedef unsigned short int uint16_t;
- typedef unsigned int uint32_t;
- typedef unsigned __int64 uint64_t;
- /* 7.18.1.2 */
- /* smallest type of at least n bits */
- /* minimum-width signed integer types */
- typedef signed char int_least8_t;
- typedef signed short int int_least16_t;
- typedef signed int int_least32_t;
- typedef signed __int64 int_least64_t;
- /* minimum-width unsigned integer types */
- typedef unsigned char uint_least8_t;
- typedef unsigned short int uint_least16_t;
- typedef unsigned int uint_least32_t;
- typedef unsigned __int64 uint_least64_t;
- /* 7.18.1.3 */
- /* fastest minimum-width signed integer types */
- typedef signed int int_fast8_t;
- typedef signed int int_fast16_t;
- typedef signed int int_fast32_t;
- typedef signed __int64 int_fast64_t;
- /* fastest minimum-width unsigned integer types */
- typedef unsigned int uint_fast8_t;
- typedef unsigned int uint_fast16_t;
- typedef unsigned int uint_fast32_t;
- typedef unsigned __int64 uint_fast64_t;
- /* 7.18.1.4 integer types capable of holding object pointers */
- typedef signed int intptr_t;
- typedef unsigned int uintptr_t;
- /* 7.18.1.5 greatest-width integer types */
- typedef signed __int64 intmax_t;
- typedef unsigned __int64 uintmax_t;
