원래 노키아 핸드폰에서 사용되던 LCD인데 PCD8544 컨트롤러를 사용하고 있습니다. 그래픽 LCD라 간단한 그래픽 출력도 가능한데 가로 x 세로가 84x48의 해상도를 가집니다.

문자를 출력해보니 가로 12자가 들어가고 6줄이 가능합니다..

아래 5개 핀은 순서대로 아래처럼 연결해주고

아두이노 7번핀 ---- LCD 3번핀

아두이노 6번핀 ---- LCD 4번핀

아두이노 5번핀 ---- LCD 5번핀

아두이노 4번핀 ---- LCD 6번핀

아두이노 3번핀 ---- LCD 7번핀

LCD8번핀과 LCD1번핀은 3.3V에 같이 연결해주고 LCD2번핀은 GROUND에 연결해주었습니다...

https://github.com/sparkfun/GraphicLCD_Nokia_5110/tree/master/Firmware/Nokia_5110_Arduino_Example에 공개되어 있는 예제를 올려서 태스트 해봤는데.. 대문자는 제대로 나오는데 소문자는 한칸씩 밀리는 현상이 있어서 ~~아래 처럼 한줄을 넣어주었더니...일단 대소문자는 제대로 나 옵니다..~~

오른쪽 처럼 \ 문자를 지워줘야 제대로 나오네요.. 예제 코드 문제가 아니었습니다..

사진은 흐리게 나왔지만 실제로 보면 백라이트가 상당히 밝습니다.. \는 두번 \\ 해주어야 출력이 됩니다.

This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license).
This code writes a series of images and text to the Nokia 5110 84x48 graphic LCD:
http://www.sparkfun.com/products/10168
Do not drive the backlight with 5V. It will smoke. However, the backlight on the LCD seems to be
happy with direct drive from the 3.3V regulator.
Although the PCD8544 controller datasheet recommends 3.3V, the graphic Nokia 5110 LCD can run at 3.3V or 5V.
No resistors needed on the signal lines.
You will need 5 signal lines to connect to the LCD, 3.3 or 5V for power, 3.3V for LED backlight, and 1 for ground.
