/* Nokia 5100 LCD Example Code with Added Joystick by Robojax
   Graphics driver and PCD8544 interface code for SparkFun's
   84x48 Graphic LCD.
   https://www.sparkfun.com/products/10168
   Original Source code
https://github.com/sparkfun/GraphicLCD_Nokia_5110

  This stuff could all be put into a library, but we wanted to
  leave it all in one sketch to keep it as transparent as possible.

  Hardware: (Note most of these pins can be swapped)
    Graphic LCD Pin ---------- Arduino Pin
       1-VCC       ----------------  5V
       2-GND       ----------------  GND
       3-SCE       ----------------  7
       4-RST       ----------------  6
       5-D/C       ----------------  5
       6-DN(MOSI)  ----------------  11
       7-SCLK      ----------------  13
       8-LED       - 330 Ohm res --  9
   The SCLK, DN(MOSI), must remain where they are, but the other 
   pins can be swapped. The LED pin should remain a PWM-capable
   pin. Don't forget to stick a current-limiting resistor in line
   between the LCD's LED pin and Arduino pin 9!
