Espruino Pico and Nokia 5110 display example

These displays were used in old Nokia 5110 cell phones. It is a 84×48 pixel monochrome LCD display and you can use it for graphics, text or bitmaps. To use the display, you will require 5 digital output pins. Another pin can be used to control the backlight.

The display driver is a PCD8544 chip (which is another name for the display), and you can safely run the display off 3.3v

Here is the connections I used
