        ======
        
        An interrupt-based Python 2/3 library for reading matrix_ keypad_ key presses using Raspberry Pi GPIO pins.
        
        .. _matrix: http://www.adafruit.com/products/419
        .. _keypad: http://www.adafruit.com/products/1824
        
        .. code-block:: python
        
        	pip install pad4pi
        
        Tested on a Raspberry Pi B+ using a `4x3 matrix keypad`_ but it should work with 4x4 and other sizes.

        Usage
        =====
        
        .. code-block:: python
        
          from pad4pi import rpi_gpio
        
          KEYPAD = [
              [1, 2, 3],
              [4, 5, 6],
              [7, 8, 9],
              ["*", 0, "#"]
          ]
        
          ROW_PINS = [4, 14, 15, 17] # BCM numbering
          COL_PINS = [18, 27, 22] # BCM numbering
        
          factory = rpi_gpio.KeypadFactory()
        
          # Try factory.create_4_by_3_keypad 
          # and factory.create_4_by_4_keypad for reasonable defaults
          keypad = factory.create_keypad(keypad=KEYPAD, row_pins=ROW_PINS, col_pins=COL_PINS)
        
          def printKey(key):
              print(key)
        
          # printKey will be called each time a keypad button is pressed
          keypad.registerKeyPressHandler(printKey)
        
        When your program exits, call ``keypad.cleanup()`` to ensure the Raspberry Pi's GPIO pins are reset.
