     48      Specifies an array of numeric keycode values to
     49      be used for the channels. If this property is
     50      omitted, KEY_A, KEY_B, etc are used as defaults.
     51      The array must have exactly six entries.

     58      Defines the gain of the sensor circuitry. This
     59      effectively controls the sensitivity, as a
     60      smaller delta capacitance is required to
     61      generate the same delta count values.

     66      By default the interrupt pin is active low
