Interfacing of Nokia display with an Arduino

In this tutorial, we will see the complete guide on NOKIA 5110 and its interfacing with Arduino. This display has a wide application of displaying data. This display module is very cheap, and you can use it with many development boards and micro-controller. Nokia display is an 84×48(or 48×84) graphic LCD that can control/display any data with the help of an internal controller called PCD8544. It is a great choice to display data.

The main objective of this tutorial will be:

• We will learn the basics about NOKIA5110 LCD
• We will learn how to interface it with Arduino
• We will generate the code for displaying a text

Basics About Nokia 5110 Display:

Nokia 5110 has an interior controller/Driver named PCD8544. With the assistance of this, we will display the info onto LCD. The PCD8544 could be a low-power CMOS LCD controller/driver designed to drive a graphic display of 48 rows and 84 columns.

All necessary functions for the display are provided during a single chip, including on-chip generation of LCD supply and bias voltages, leading to a minimum of external components and low power consumption.

The PCD8544 are going to be interfacing to microcontrollers by a serial bus interface. The PCD8544 is manufactured in n-well CMOS technology.

from the below link, you can download the datasheet for:

• Nokia5110 LCD
• PCD8544 controller/driver

NOKIA 5110 LCD screen uses SPI protocol to search out a DIN pin which might even be called MOSI(Master-Out Slave-In). So, all we'll do is pass commands with a pair of 8-bit data through the DIN pin while using the opposite pins(like DC, CE, and CLK pins) simultaneously and appropriately.

Specifications

• 48 x 84 Dot LCD
• Serial Bus Interface with maximum high speed 4.0 Mbits/S
• Internal Controller No.PCD8544
• LED Back-Light
• Run at Voltage 2.7 -5.0 Volt
• Low power consumption; it is suitable for battery applications
• Temperature range from -25 ̊C to +70 ̊C
• Support Signal CMOS Input

Pinout

Let's understand the pinout of this display. We will also see the significance of each pin.

• RST – Signal RESET for the operation of LCD
• CE – Chip Enable, Pin CHIP ENABLE to control operation.
• D/C – Pin to configure the information formats between Data and Command.
• DIN – Serial Input, Pin DATA (SERIAL DATA LINE)
• CLK – Pin CLOCK (SERIAL CLOCK LINE)
• VCC – 3.3V, to provide power supply from the microcontroller
• LIGHT – Backlight Control, to control operation of LED (Back Light)
• GND – Ground

Components Required

For interfacing and LCD with the Arduino, we will need the following components :

	Arduino with cable	Add to cart
	Jumper wires	Add to cart
	Breadboard	Add to cart
	Nokia5110 LCD	Add to cart

Interfacing with Arduino

Make connections as shown in the diagram:

The wiring of Nokia5110 LCD with Arduino is explained as follows:

Nokia 5110 LCD	The Arduino
RST	3
CE	4
DC	5
DIN	6
CLK	7
VCC	3.3V
BL	3.3V (through 220Ω resistor)
GND	GND

Coding

Before proceeding to the coding part, we need to download few libraries to execute code properly. In the Arduino IDE, go to Tools -> Manage Libraries. Search for “PCD8544 Nokia”.

You need to select the library “Adafruit PCD8544 Nokia 5110 LCD Library ” and click on install. One more additional library we need to install for displaying graphics on the LCD, which is ” Adafruit GFX Library. “

After installing these two libraries, we need to write code. With the help of the following code, we will display the text on Nokia LCD

#include <SPI.h>
#include <Adafruit_GFX.h>
#include <Adafruit_PCD8544.h>

/* Declare LCD object for software SPI
 Adafruit_PCD8544(CLK,DIN,D/C,CE,RST);*/
Adafruit_PCD8544 display = Adafruit_PCD8544(7, 6, 5, 4, 3);

void setup()
{
  /* Initialize the Display*/
  display.begin();

  /* Change the contrast using the following API*/
  display.setContrast(57);

  /* Clear the buffer */
  display.clearDisplay();
  
  /* Now let us display some text */
  display.setTextColor(WHITE, BLACK);
  display.setCursor(4,8);
  display.setTextSize(1);
  display.println("|Electronics|");
  display.setCursor(28,20);
  display.println("|Hub|");
  display.setCursor(12,32);
  display.setTextColor(BLACK);
  display.println("Nokia 5110");
  display.display();
  delay(1000);    
}

void loop()
{
  /* You can implement your display logic here*/  
}

Output

Conclusion

We just learned a simple project of displaying text on this LCD. At the advanced level, you can display bitmap images and much more. I hope you will find this article helpful. please comment if
