How to Display Bitmap Images on Nokia Arduino LCD

Hello world! I would like to introduce you to this project on how to load graphical images on nokia display using arduino, those images are Bitmap Graphics, We are going to design our own bitmap graphics using Paint.net application and then learn how to load them using the Arduino IDE. Let's get started!

What Will I Learn?

Write here briefly the details of what the user is going to learn in a bullet list.

• You will learn connect eclectronic components to arduino
• You will learn how to convert image to bmp format
• You will learn how to load graphic to nokia 5110 display
• You will learn how to make a sketch code to arduino IDE

Requirements

• Step 1: Gather all the Requirements

HARDWARE

• Nokia 5110 LCD Display
• Arduino Microcontroller board
• Connecting wires
• Breadboard
• Usb cable
• PC
• Extra battery pack

Difficulty

This is BASIC electronic tutorial I will provide the connection of pin to arduino and the sketch code to make our programming easily.

• Step 2: Build the Display

I use this display on my recent gamebuino tutorial, This display is made of 84x48 individual pixels, so you can use it for graphics, text or bitmaps. so less expensive than using oled display. this display module has built in 8 pin outputs, the power pins GND and VCC the LIGHT pin and the 4 data pin which will be connected to specified arduino pins. the connection of the pins on my recent gamebuino tutorial is different from this tutorial.

Nokia LCD	ARDUINO
RST	D12
CE	D11
DC	D10
DIN	D9
CLK	D8
VCC	3.3V
LIGHT	GND
GND	GND

Follow the 'Nokia 5110/3310 Monochrome LCD' tutorial from Adafruit to hookup and test your lcd.

Arduino Nokia LCD address Code:

LCD5110 lcd(8,9,10,12,11);
#define SCR_CLK 8;  
 #define SCR_DIN 9;
 #define SCR_DC  10;
 #define SCR_CS  11;
 #define SCR_RST 12;

• Step 3: Download the arduino software and libraries

1. Download the Arduino IDE for your specific operating system. I’ll leave a link to where you can download this software: https://www.arduino.cc/en/Main/Software

2. Adafruit-GFX-Library; https://github.com/adafruit/Adafruit-GFX-Library

3. Adafruit-PCD8544-Nokia-5110-LCD-library; https://github.com/adafruit/Adafruit-PCD8544-Nokia-5110-LCD-library/

INCLUDE LIBRARIES TO ARDUINO IDE

We have 2 options to add library to arduino software , the option (1) Add zipfile library by manually selecting the library .zipfile to do this, Open the arduino software and look for SKETCH navigate on include library- select .ZIP library then locate the downloaded nokia 5110 library, wait for the process until its successfully added to your libraries folder.

The option (2) is easier than the option 1, the search and download process. select the include library then manage libraries, search for the libraries you want to run in the program, select file version to download.

libraries belong in a subdirectory of the Arduino application directory: ARDUINO/lib/targets/libraries, On Windows, it would be My Documents\Arduino\libraries. To add your own library, create a new directory in the libraries directory with the name of your library. The folder should contain a C or C++ file with your code and a header file with your function and variable declarations. It will then appear in the Sketch | Import Library menu in the Arduino IDE.

• Step 4: Build Graphics .Bitmap format

Let’s create a simple bitmap image in Paint and then load it into the Nokia 5110 display. you can download the paint application using this paint.net 4.0.21

First, we are going to create a new File by ctrl+n, the dimensions are 84 width pixels and 48 hight, these are dimensions of the Nokia 5110 LCD display

The white board will going zoom out that’s the new file. As you can see, it is too small we have to zoom in with Ctrl + in order to be able to work with it. So, let’s now create some simple graphics. I’m going to use the shape tool here, you can use any tool you like from the software and draw some simple shapes you can click here and choose any shape you like.

We can be able move it around, then I have to deselect it and next to it I’m going to draw a star. I can move it around as well and now we are ready to save this document.

We are going to save it as a bitmap, NOT the other image format png/imag .etc be careful, bitmap and we can give it any name we want for example star.bmp and save. Okay, it is now saved.

---

• Step 6: Convert Bitmat image to Byte C arrays

We are going to use the LCD Assistant software, it is a free tool for converting monochromatic bitmaps images to data C file arrays for for embedded systems with microcontrollers and graphics monochromatic LCD displays download LCD Assistant software

We are going to use the instruction from the website, so first convert image from bitmap file to data array select from File menu command 'Load image'. then locate the bmp file, remember the file name you used on saving the image from paint, lets say star look for the filename star in bmp format from your dicuments.

Next, select byte orientation If in data array must be image size (width and height) select 'Include size' checkbox and specify endianness of size. Size are placed in two 16-bit variables at the begin of data array. Next, specify pixels/byte parameter, the width must be 84 pizels and the height is 48 pixels of the nokia 511- lcd Display

click on FILE then SAVE OUPUT edit the filename you want to use the click save button.

Select the .c from you documents open the file with your notes app, the byte arrays should reflect from the file, for example the code .c of the star that i make recently.

#include <avr/pgmspace.h>
const unsigned char star [] PROGMEM = {
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 
};

• Step 7: PROGRAMMING

By using the the nokia5110 lcd graph library we can be able to write a code easily

The first line should include the nokia5110 library and define the address pin, you can get the address from the address code on the build the display part of the tutorial.

#include >LCD5110_Graph.h>
LCD5110 lcd(8,9,10,12,11);

Define the External address of the .c file from example i used the code star name of the byte arrays you can edit the uint8_t code from your own .c filename

extern uint8_t star[];

setup() method is ran once at the just after the Arduino is powered up and the loop() method is ran continuously afterwards.
setup() is where you want to do any initialisation steps, and in loop() you want to run the code over and over again.

void setup()
{
  lcd.InitLCD(); // start the lcd
}
void loop()
{
  lcd.clrScr();
  lcd.drawBitmap(0,0,star,84,48); // .c address and dimension of the image to be displayed
  lcd.update();
  delay(2000); // delay time 1000 is 1sec.
}

• Step 8: Experimental Procedures

Include .C file to lcd5110_graph library, locate the .c file lets say star.c, cut the file then paste it to nokialcd library ARDUINO/LIBRARIES/LCD5110_GRAPH

• Step 9: Upload code to Microcontroller board

Connect the arduino uno board nano/mega/r3 to your computer via type b usb cable.
your computer will automatically scan the device driver, to verify the board of the arduino, on the IDE click >. TOOLS then verify the board type and PORT where the USB is connected.

once done click upload, it will compile the sketch first before uploading.

When the LCD main screen is turned on as shown below without any problem! Youre now ready to make your own images to be shown from the LCD( you can turn off the backlight by unpining the LIGHT pin of the LCD to arduino)

---

We can also use bitmap images on google and convert it to byte C arrays code to display on 5110 LCD for example i will use thid mini BMW

_{ACTUAL IMAGE}

_{IMAGE DISPLAYED TO LCD}

You cannot load any colored pictures only monochrome dots photos with 84x48 pixels, you can use any dots to bitmap softwares to convert or make your own images to be display. so thats it thank you for reading.
