Overview of Nokia5110 Display

Nokia5110 is a graphical display that can display text, images, and various patterns.

It has a resolution of 48x84 and comes with a backlight.

It uses SPI communication to communicate with a microcontroller/microprocessor.

Data and commands can be sent through the processor to the display to control the display output.

It has 8 pins.

For more information about the Nokia5110 display and how to use it, refer the topic Nokia5110 Graphical Display in the sensors and modules section.

As Nokia5110 uses SPI communication, we need to make sure that the SPI interface of Raspberry Pi is enabled. If it is not enabled then using we have to make it enable.

How to enable SPI?

To enable SPI on Raspberry Pi, enter the following command

sudo raspi-config

then, a window will pop up in which select  Interface Options

After selecting the Interface option, enable the SPI interface. And then reboot Raspberry Pi.

Now, we can establish SPI communication.

Here, we are going to interface the Nokia5110 display with Raspberry Pi 3

We will be using the theNokia5110 Python library by Adafruit from GitHub.

Download the Adafruit Nokia LCD Python library.

Extract the above library and install it in the directory of the above library by executing the following command,

sudo python setup.py install

Also, we need to install python imaging library as given below,

sudo apt-get install python-imaging

Once the library has been added, we can test the Nokia LCD interfacing with Raspberry Pi by executing existing examples kept in examples folder of the library.

Here, we are going to create a small python program in which we will display text, image,s and flying bird animation. This python program file along with sample images is kept in the “example” folder of the library provided in the attachment.

Note: While displaying image on Nokia5110 display, we have to provide image to the program. This image should be of display size (84x48 here). If we provide image with other resolution it will give error.
