Adafruit’s PCD8544 library makes it easier and providing more features for playing Nokia 5110 LCD module with Arduino. I re-packaged the library files and it can be downloaded here.
LCD module connection with Arduino (LCD pin – Arduino pin):
- RST – Pin 3
- CE – Pin 4
- D/C – Pin 5
- DIN – Pin 6
- CLK – Pin 7
- VCC – 3.3v
- LIGHT – Pin 13
- GND – GND
You can easily get the example code run with Arduino IDE (don’t forget to place library files in IDE’s libraries folder). This time I managed to compile and upload the test sketch to Arduino Leonardo with my just-updated Arduino Uploader (with PCD8544 libraries packaged in).
