| FlagStatus EXTI_GetFlagStatus | ( | uint32_t | 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: - EXTI_Linex: External interrupt line x where x(0..19)
- Return values

| ITStatus EXTI_GetITStatus | ( | uint32_t | EXTI_Line | ) |
Checks whether the specified EXTI line is asserted or not.
- Parameters

| void EXTI_Init | ( | EXTI_InitTypeDef * | EXTI_InitStruct | ) |
Initializes the EXTI peripheral according to the specified parameters in the EXTI_InitStruct.
Initializes the EXTI peripheral according to the specified parameters in the EXTI_InitStruct. EXTI_Line specifies the EXTI line (EXTI0....EXTI35). EXTI_Mode specifies which EXTI line is used as interrupt or an event. EXTI_Trigger selects the trigger. When the trigger occurs, interrupt pending bit will be set. EXTI_LineCmd controls (Enable/Disable) the EXTI line.
- Parameters
-
EXTI_InitStruct pointer to a EXTI_InitTypeDef structure that contains the configuration information for the EXTI peripheral.
- Return values
-
None

| void EXTI_StructInit | ( | EXTI_InitTypeDef * | EXTI_InitStruct | ) |
Fills each EXTI_InitStruct member with its reset value.
- Parameters
-
EXTI_InitStruct pointer to a EXTI_InitTypeDef structure which will be initialized.
- Return values
-
None
