Introduction 

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.

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

It has 8 pins.

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

Example

Displaying text, rectangular, circle, line, images etc. on Nokia5110 display.

Here, we will be using nokia-5110-lcdlibrary from Particle Library. 

There is very small change in this developed library to work. To make the changes to the nokia-5110-lcd library we have to edit that library. But these existing libraries are readable only.

So, to make changes follow the steps given below to add and change the library.

1.      Go to web or Desktop IDE

2.      Create a new APP.

3.      Copy the code given below and paste it in the ino file that you created in the new APP.

4.      Now click on create a new library and give the name nokia-5110-lcd.

5.      Now Click on Library Icon.

6.      Type nokia-5110-lcd and click on that and open it.

7.      Copy the code from nokia-5110-lcd.cpp and nokia-5110-lcd.h and paste inthe respective library files you created in step 4.

8.      Click on nokia-5110-lcd.cppin your library, and add SPI.setClockSpeed(4, MHZ); after SPI.begin();asshown in figure below

9.      Now compile and flash it on your photon board.
