Interrupt Config

Definition

    typedef struct INTERRUPT_CONFIG{
        Interrupt extInt;
        Pin pin;
        Polarity polarity;
        int enable;
        Resistor resistor;
        void *callback;
    } Interrupt_Config;

The Interrupt_Config structure is used for interrupt initialization and updating.

Parameters

• extInt: extInt specifies which interrupt should be modified.
• pin: pin specifies which pin should be used as the interrupt trigger.
• polarity: this specifies what type of edge an interrupt should be triggered on.
• enable: this defines whether an interrupt is enabled on initialization or not.
• resistor: this specifies whether a pull-up or pull-down resistor should be used internally.
• callback: This is the callback function that will be triggered when an interrupt is generated. Please refer to the callback function for more information.
