疑问：GPIO_TypeDef Struct Reference

3万 · 2010-7-9 15:09

以下内容出自帮助文件stm32f10x_stdperiph_lib_um.chm其中这个数据结构的数据字段
GPIO_TypeDef Struct Reference
[Peripheral_registers_structures] General Purpose I/O. More... #include <stm32f10x.h>


Data Fields
__IO uint32_t	BRR
__IO uint32_t	BSRR
__IO uint32_t	CRH
__IO uint32_t	CRL
__IO uint32_t	IDR
__IO uint32_t	LCKR
__IO uint32_t	ODR

Detailed DescriptionGeneral Purpose I/O.

typedef struct
{ __IO uint32_t CRL;
__IO uint32_t CRH;
__IO uint32_t IDR;
__IO uint32_t ODR;
__IO uint32_t BSRR;

__IO uint32_t BRR;
__IO uint32_t LCKR;
} GPIO_TypeDef;

关于这几个数据的解释，help文件里面相当含糊。找ST网站的芯片规格书，GPIO就一笔带过，所以看了还是不明白这几个字段什么意思。谁给我一个详细点的文档？

上面乱码：
是这样的文字：
GPIO_TypeDef Struct Reference
[Peripheral_registers_structures]
General Purpose I/O. More...
#include <stm32f10x.h>

Data Fields
__IO uint32_t  BRR
__IO uint32_t  BSRR
__IO uint32_t  CRH
__IO uint32_t  CRL
__IO uint32_t  IDR
__IO uint32_t  LCKR
__IO uint32_t  ODR

--------------------------------------------------------------------------------

Detailed Description
