STM32 uint32_t 在哪个头文件里

应当包含类似typedef.h之类的头文件

或者在前面加：

typedef

signed

char

int8

//!<

signed

8

bit

integer

typedef

unsigned

char

uint8

//!<

unsigned

8

bit

integer

typedef

signed

short

int16

//!<

signed

16

bit

integer

typedef

unsigned

short

uint16

//!<

unsigned

16

bit

integer

typedef

signed

long

int32

//!<

signed

32

bit

integer

typedef

unsigned

long

uint32

//!<

unsigned

32

bit

integer

typedef

unsigned

char

bool

//!<

boolean

data

type

__IO就是volatile

uint32_t就是32位无符号整形数。

这都是

ARM公司

无聊滴在CMSIS库里面定义的。

STM32

库1.x

2.x都没有这玩意，到了3.0以后引入了CMSIS就有了。
