Module Contents
---------------

.. py:class:: ExtInt(pin, mode, pull, callback)

   Create an ExtInt object:

     - ``pin`` is the pin on which to enable the interrupt (can be a pin object or any valid pin name).
     - ``mode`` can be one of:
       - ``ExtInt.IRQ_RISING`` - trigger on a rising edge;
       - ``ExtInt.IRQ_FALLING`` - trigger on a falling edge;
       - ``ExtInt.IRQ_RISING_FALLING`` - trigger on a rising or falling edge.
     - ``pull`` can be one of:
       - ``pyb.Pin.PULL_NONE`` - no pull up or down resistors;
       - ``pyb.Pin.PULL_UP`` - enable the pull-up resistor;
       - ``pyb.Pin.PULL_DOWN`` - enable the pull-down resistor.
     - ``callback`` is the function to call when the interrupt triggers.  The
       callback function must accept exactly 1 argument, which is the line that
       triggered the interrupt.


   .. py:method:: disable() -> None

      Disable the interrupt associated with the ExtInt object.
      This could be useful for debouncing.



   .. py:method:: enable() -> None

      Enable a disabled interrupt.



   .. py:method:: line() -> int

      Return the line number that the pin is mapped to.



   .. py:method:: regs() -> _typeshed.Incomplete
      :classmethod:


      Dump the values of the EXTI registers.



   .. py:method:: swint() -> _typeshed.Incomplete

      Trigger the callback from software.



   .. py:attribute:: IRQ_FALLING
      :type:  _typeshed.Incomplete

      interrupt on a falling edge


   .. py:attribute:: IRQ_RISING
      :type:  _typeshed.Incomplete

      interrupt on a rising edge


   .. py:attribute:: IRQ_RISING_FALLING
      :type:  _typeshed.Incomplete

      interrupt on a rising or falling edge
