class Digital Input
===================

Read the state of a Digital Input.
The idle state of a Digital Input is High due to the pull up resistor on the PCB. 


Constructor
-----------

.. class:: omc048.digital_input(id: integer)

   Create a digital input object associated with a digital input.

   - ``id`` is the Digital Input number 1 to 2, corresponding to pin 51 and 52.


Methods
-------

.. method:: digital_input.get()
   
   Returns the digital input state.

   - ``state`` is 1 or 0, corresponding to High and Low.



Example
-------

The following example reads the states from the digital inputs. ::

    import omc048
        
    d1 = omc048.digital_input(1)
    d2 = omc048.digital_input(2)

    d1.get()
    d2.get()
