| 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
