- ******************************************************************************
- * @file stm32f0xx_hal_exti.c
- * @author MCD Application Team
- * @brief EXTI HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the Extended Interrupts and events controller (EXTI) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- *
- @verbatim
- ==============================================================================
- ##### EXTI Peripheral features #####
- ==============================================================================
- [..]
- (+) Each Exti line can be configured within this driver.
-
- (+) Exti line can be configured in 3 different modes
- (++) Interrupt
- (++) Event
- (++) Both of them
-
- (+) Configurable Exti lines can be configured with 3 different triggers
- (++) Rising
- (++) Falling
- (++) Both of them
-
- (+) When set in interrupt mode, configurable Exti lines have two different
- interrupts pending registers which allow to distinguish which transition
- occurs:
- (++) Rising edge pending interrupt
- (++) Falling
-
- (+) Exti lines 0 to 15 are linked to gpio pin number 0 to 15. Gpio port can
- be selected through multiplexer.
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
-
- (#) Configure the EXTI line using HAL_EXTI_SetConfigLine().
- (++) Choose the interrupt line number by setting "Line" member from
- EXTI_ConfigTypeDef structure.
- (++) Configure the interrupt and/or event mode using "Mode" member from
- EXTI_ConfigTypeDef structure.
- (++) For configurable lines, configure rising and/or falling trigger
- "Trigger" member from EXTI_ConfigTypeDef structure.
- (++) For Exti lines linked to gpio, choose gpio port using "GPIOSel"
- member from GPIO_InitTypeDef structure.
-
- (#) Get current Exti configuration of a dedicated line using
- HAL_EXTI_GetConfigLine().
- (++) Provide exiting handle as parameter.
- (++) Provide pointer on EXTI_ConfigTypeDef structure as second parameter.
-
- (#) Clear Exti configuration of a dedicated line using HAL_EXTI_GetConfigLine().
- (++) Provide exiting handle as parameter.
-
- (#) Register callback to treat Exti interrupts using HAL_EXTI_RegisterCallback().
- (++) Provide exiting handle as first parameter.
- (++) Provide which callback will be registered using one value from
- EXTI_CallbackIDTypeDef.
- (++) Provide callback function pointer.
-
- (#) Get interrupt pending bit using HAL_EXTI_GetPending().
-
- (#) Clear interrupt pending bit using HAL_EXTI_GetPending().
-
- (#) Generate software interrupt using HAL_EXTI_GenerateSWI().
