#366 Nokia 5110 LCD/AdafruitSoftwareSPI

A quick Nokia 5110 LCD test using software SPI and the Adafruit PCD8544 library.

Notes

I've been having SPI conflicts with other libraries I've used for controlling the Nokia 5110 LCD, so time to pull out the big guns - the wonderful Adafruit library set which includes a PCD8544 module.

5110 LCD SPI Configuration

This is a test of the software SPI configuration, which means we steer clear of the hardware SPI pins (10-13 on an Arduino Uno).

Here's the mapping from the terminology used by my particular 5110 module and pins on an Arduino Uno.

Pin Usage Arduino Uno Pin
RST reset 7
CE/SCE/SS chip enable 6
DC/CSN data/command select 5
DIN data in 8 SPI MOSI
CLK clock 9 SPI SCK
VCC power 5V
BL Backlight on when GND n/c
GND Ground GND
