Nokia 5110 LCD를 arduino uno에 연결하기Arduino Uno2015. 11. 25. 18:47

반응형
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 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.
