Adding the Nokia 5110 LCD to your Arduino data logger

From the comments on our ChipKIT based weather station using BME280 sensor module post, Edward Mallon writes:

A lot of us have ended up at this sensor / screen combination. But I couldn’t afford the extravagance of six dedicated control lines on our little pro mini based loggers.
However with some slight modification, you can drive the Nokia 5110 LCD with only 3 control lines, and power the display from a digital pin

  1. This is a follow-up to our post about using Nokia 5110 screens on three unused analog lines with shift-out​. That saved me from messing with the hardware SPI bus which we reserve for the SD cards. A secondary benefit is that the code is really lean, on the order of about 250 bytes for the default font after the compile if you already have EEprom.h in the build anyway. The font, however takes up about 500 bytes, and I wanted the smallest possible footprint so that we could add live data output to loggers that are already compile near the memory limits. As it turns out, stuffing those fonts into the internal EEprom was pretty easy to do:
