#085 Lcd5110/BareBack

Test driving a Nokia 5110 LCD Display with an Arduino and the raw command set

Here’s a quick video of the circuit in action:

Lcd5110BareBack demo

Notes

This quick demo is inspired by Julian Ilett’s tutorial series on YouTube.

It runs a simple demo cycle, including the reading and display of a voltage from the A0 pin.

There are a few commonly-used libraries - such as ladyada’s - however this sketch uses the instruction set for device directly, as documented in the PCD8544 datasheet.

A couple of observations:

  • it seems different modules have different pin arrangements, so it is important to match the 5110 pins to the Arduino correctly.
  • it works fine with 5V logic connections
  • with 5V logic connections, there appears to be no need to connect Vcc, it works fine disconnected! In fact, some circuits that “do the right thing” and connect 3.3V supply to Vcc are not behaving as might be execpted. At least with my module, the Vcc is already taken up to 4.2+V by the login pins.

This is the module I’m using:

This page is a web-friendly rendering of my project notes shared in the LEAP GitHub repository.

LEAP is my personal collection of electronics projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:

Feel free to borrow liberally, and if you spot any issues do let me know. See the individual projects for credits where due. There are even now a few projects contributed by others - send your own over in a pull request if you would also like to add to this collection.
