Function Documentation

◆ HAL_GPIO_Init()

void HAL_GPIO_Init	(	GPIO_TypeDef *	GPIOx,
		GPIO_InitTypeDef *	GPIO_Init )

#include <stm32f4xx_hal_gpio.h>

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

Parameters

GPIOx	where 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_Init	pointer to a GPIO_InitTypeDef structure that contains the configuration information for the specified GPIO peripheral.

Return values

None

◆ HAL_GPIO_DeInit()

void HAL_GPIO_DeInit	(	GPIO_TypeDef *	GPIOx,
		uint32_t	GPIO_Pin )

#include <stm32f4xx_hal_gpio.h>

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