void HAL_GPIO_DeInit ( GPIO_TypeDef *  GPIOx,
uint32_t  GPIO_Pin 
)

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

Parameters:
GPIOxwhere x can be (A..K) to select the GPIO peripheral for STM32F429X device or x can be (A..I) to select the GPIO peripheral for STM32F40XX and STM32F427X devices.
GPIO_Pinspecifies 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:
GPIOxwhere x can be (A..K) to select the GPIO peripheral for STM32F429X device or x can be (A..I) to select the GPIO peripheral for STM32F40XX and STM32F427X devices.
GPIO_Initpointer to a GPIO_InitTypeDef structure that contains the configuration information for the specified GPIO peripheral.
Return values:
None
