void HAL_GPIO_DeInit	(	GPIO_TypeDef *	GPIOx,
		uint32_t	GPIO_Pin
	)

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

Parameters:

GPIOx,:	where x can be (A..G depending on device used) to select the GPIO peripheral
GPIO_Pin,:	specifies the port bit to be written. This parameter can be one of GPIO_PIN_x where x can be (0..15).

Return values:

None

void HAL_GPIO_Init	(	GPIO_TypeDef *	GPIOx,
		GPIO_InitTypeDef *	GPIO_Init
	)

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

Parameters:

GPIOx,:	where x can be (A..G depending on device used) to select the GPIO peripheral
GPIO_Init,:	pointer to a GPIO_InitTypeDef structure that contains the configuration information for the specified GPIO peripheral.

Return values:

None
