Function Documentation

void HAL_GPIO_DeInit	(	GPIO_TypeDef *	GPIOx,
		uint32_t	GPIO_Pin
	)

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

Parameters:

GPIOx	where x can be (A..H) to select the GPIO peripheral for STM32L4 family
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

void HAL_GPIO_Init	(	GPIO_TypeDef *	GPIOx,
		GPIO_InitTypeDef *	GPIO_Init
	)

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

Parameters:

GPIOx	where x can be (A..H) to select the GPIO peripheral for STM32L4 family
GPIO_Init	pointer to a GPIO_InitTypeDef structure that contains the configuration information for the specified GPIO peripheral.

Return values:

None
