void GPIO_DeInit ( GPIO_TypeDef * GPIOx )

De-initializes the GPIOx peripheral registers to their default reset values.

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..K) to select the GPIO peripheral for STM32F405xx/407xx and STM32F415xx/417xx devices x can be (A..I) to select the GPIO peripheral for STM32F42xxx/43xxx devices. x can be (A, B, C, D and H) to select the GPIO peripheral for STM32F401xx devices.

Return values

None

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 for STM32F40xx/41xx and STM32F427x/437x devices.

Return values

None

Parameters

GPIOx where x can be (A, B, C, D, E or F) to select the GPIO peripheral.

Return values

None

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..K) to select the GPIO peripheral for STM32F405xx/407xx and STM32F415xx/417xx devices x can be (A..I) to select the GPIO peripheral for STM32F42xxx/43xxx devices. x can be (A, B, C, D and H) to select the GPIO peripheral for STM32F401xx devices.
GPIO_InitStruct	pointer to a GPIO_InitTypeDef structure that contains the configuration information for the specified GPIO peripheral.

Return values

None

Parameters

GPIOx	where x can be (A..I) to select the GPIO peripheral for STM32F40xx/41xx and STM32F427x/437x devices.
GPIO_InitStruct	pointer to a GPIO_InitTypeDef structure that contains the configuration information for the specified GPIO peripheral.

Return values

None

Parameters

GPIOx	where x can be (A, B, C, D, E or F) to select the GPIO peripheral.
GPIO_InitStruct	pointer to a GPIO_InitTypeDef structure that contains the configuration information for the specified GPIO peripheral.

Note: GPIO_Pin: selects the pin to be configured: GPIO_Pin_0->GPIO_Pin_15 for GPIOA, GPIOB, GPIOC, GPIOD and GPIOE; GPIO_Pin_0->GPIO_Pin_2, GPIO_Pin_4, GPIO_Pin_6, GPIO_Pin_9 and GPIO_Pin_10 for GPIOF.

void GPIO_PinLockConfig	(	GPIO_TypeDef *	GPIOx,
		uint16_t	GPIO_Pin
	)

Locks GPIO Pins configuration registers.

Locks GPIO Pins configuration registers. The locked registers are GPIOx_MODER, GPIOx_OTYPER, GPIOx_OSPEEDR, GPIOx_PUPDR, GPIOx_AFRL and GPIOx_AFRH.

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..K) to select the GPIO peripheral for STM32F405xx/407xx and STM32F415xx/417xx devices x can be (A..I) to select the GPIO peripheral for STM32F42xxx/43xxx devices. x can be (A, B, C, D and H) to select the GPIO peripheral for STM32F401xx devices.
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

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 for STM32F40xx/41xx and STM32F427x/437x devices.
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

Note: The configuration of the locked GPIO pins can no longer be modified until the next reset.

Parameters

GPIOx	where x can be (A or B or D) to select the GPIO peripheral.
GPIO_Pin	specifies the port bit to be written. This parameter can be any combination of GPIO_Pin_x where x can be (0..15).

Return values

None
