attachIntDio()

to enable DIO interrupt.

Enables DIO interrupts.

void attachIntDio(uint8_t u8pin, E_PIN_INT_MODE mode)

For a preconfigured pin, the first parameter is the pin number for which you want to enable interrupts, the second is the interrupt direction (rising, falling.

Interrupt handlers and event handlers are written in Application BEHAVIOR.

Example

Set up an interrupt to be generated when the DIO5 pin changes from HIGH to LOW.

void setup() {
  the_twelite.app.use<myAppClass>();
  
  pinMode(PIN_DIGITAL::DIO5, PIN_MODE::INPUT_PULLUP);
  attachIntDio(PIN_DIGITAL::DIO5, PIN_INT_MODE::FALLING);
}

void loop() {
  ;
}

Description of the interrupt handler of the application behavior myAppClass, which inverts the output setting of DIO12 when an interrupt of DIO5 is generated and displays * on the serial port Serial for events occurring after the interrupt handler is finished.
