Detailed Description

Macro Definition Documentation

◆ __HAL_GPIO_EXTI_GET_FLAG

#define __HAL_GPIO_EXTI_GET_FLAG ( __EXTI_LINE__ )

#include <stm32f4xx_hal_gpio.h>

Value:

(EXTI->PR & (__EXTI_LINE__))

Checks whether the specified EXTI line flag is set or not.

Parameters

__EXTI_LINE__ specifies the EXTI line flag to check. This parameter can be GPIO_PIN_x where x can be(0..15)

Return values

The	new state of EXTI_LINE (SET or RESET).

◆ __HAL_GPIO_EXTI_CLEAR_FLAG

#define __HAL_GPIO_EXTI_CLEAR_FLAG ( __EXTI_LINE__ )

#include <stm32f4xx_hal_gpio.h>

Value:

(EXTI->PR = (__EXTI_LINE__))

Clears the EXTI's line pending flags.

Parameters

__EXTI_LINE__ specifies the EXTI lines flags to clear. This parameter can be any combination of GPIO_PIN_x where x can be (0..15)

Return values

None

◆ __HAL_GPIO_EXTI_GET_IT

#define __HAL_GPIO_EXTI_GET_IT ( __EXTI_LINE__ )

#include <stm32f4xx_hal_gpio.h>

Value:

(EXTI->PR & (__EXTI_LINE__))

Checks whether the specified EXTI line is asserted or not.

Parameters

__EXTI_LINE__ specifies the EXTI line to check. This parameter can be GPIO_PIN_x where x can be(0..15)

Return values

The	new state of EXTI_LINE (SET or RESET).

#include <stm32f4xx_hal_gpio.h>

Value:

(EXTI->SWIER |= (__EXTI_LINE__))

Generates a Software interrupt on selected EXTI line.

Parameters
