Function Documentation

void GPIO_DeInit ( GPIO_TypeDef *  GPIOx )

Deinitializes the GPIOx peripheral registers to their default reset values.

Note:
By default, The GPIO pins are configured in input floating mode (except JTAG pins).
Parameters:
GPIOx,:where x can be (A..I) to select the GPIO peripheral.
Return values:
None

Definition at line 120 of file stm32f4xx_gpio.c.

void GPIO_Init ( GPIO_TypeDef *  GPIOx,
GPIO_InitTypeDef *  GPIO_InitStruct 
)

Initializes the GPIOx peripheral according to the specified parameters in the GPIO_InitStruct.

Parameters:
GPIOx,:where x can be (A..I) to select the GPIO peripheral.
GPIO_InitStruct,:pointer to a GPIO_InitTypeDef structure that contains the configuration information for the specified GPIO peripheral.
Return values:
None

Definition at line 182 of file stm32f4xx_gpio.c.

void GPIO_PinLockConfig ( GPIO_TypeDef *  GPIOx,
uint16_t  GPIO_Pin 
)

Locks GPIO Pins configuration registers.

Note:
The locked registers are GPIOx_MODER, GPIOx_OTYPER, GPIOx_OSPEEDR, GPIOx_PUPDR, GPIOx_AFRL and GPIOx_AFRH.
The configuration of the locked GPIO pins can no longer be modified until the next reset.
Parameters:
GPIOx,:where x can be (A..I) to select the GPIO peripheral.
GPIO_Pin,:specifies the port bit to be locked. This parameter can be any combination of GPIO_Pin_x where x can be (0..15).
Return values:
None

Definition at line 255 of file stm32f4xx_gpio.c.

void GPIO_StructInit ( GPIO_InitTypeDef *  GPIO_InitStruct )

Fills each GPIO_InitStruct member with its default value.

Parameters:
GPIO_InitStruct: pointer to a GPIO_InitTypeDef structure which will be initialized.
Return values:
None

Definition at line 234 of file stm32f4xx_gpio.c.
