Analog input (the axes) is delivered as a whole, positive number. If you need to know
if the axis is at zero (centered) or not, you will first have to calculate that center
based on the max and min values. The demo shows a bar graph for each axis expressed
-in native numerical format, plus a 'centered' X-Y axis compas showing the relationship
-of that input to the calculcated stick position.

Analog input may be jumpy and spurious, so the control has a means of 'smoothing' the
analog data by setting a movement threshold. This demo sets the threshold to 10, but
POV hats come in two flavors: four-way, and continuous. four-way POVs are restricted to
the cardinal points of the compass; continuous, or CTS POV hats can deliver input in
.01 degree increments, theoreticaly. The data is returned as a whole number; the last
-two digits are to the right of the decimal point, so in order to use this information,
-you need to divide by 100 right off the bat.

<p>Different methods are provided to retrieve the POV data for a CTS hat
versus a four-way hat.
