+    
+    Usage and assumptions:
+        the digital joystick device is directly attached to the used pins as per
+        function call, common contact to ground, using the internal pull-up's
+        but one can use external pull-up's too or even a small capaitor if device
+        shows signs of contact bounce.
+        
+    Operation modes:
+        By default it's using dynamic mode which means that the main program may
+        not see the expected pressed joystick contact in it's scan loop as another
+        joystick contact may already be active.
+        Using the static mode will capture the first joystick contact untill it's
+        been read by the getJoyValue function
+        
+    To do:
+        Adding a callable service routine to be used by the main program loop
