/* 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!
