  DogLcd Library - PingPong
 
  Demonstrates the basic use two DOGM text LCD displays.
  This sketch prints "Ping" and "Pong" alternately 
  to the displays.
 
  See the hardware documentation for wiring instuctions
  We assume  the following pins are connected:
  * For boths displays SI pin to digital pin 2
  * For boths displays CLK pin to digital pin 3
  * For boths displays RS pin to digital pin 4
  * For the "Ping" display" the CSB pin is connected to pin 5
  * For the "Pong" display" the CSB pin is connected to pin 6
  * For boths displays the RESET pin is not used (connected to +5V)
  * For boths displays the Backlight switching is not used
