84 48 lcd module arduino price

This is a quick tutorial for our 84x48 pixel monochrome LCD display. These displays are small, only about 1.5" diameter, but very readable due and comes with a backlight. This display is made of 84x48 individual pixels, so you can use it for graphics, text or bitmaps. These displays are inexpensive, easy to use, require only a few digital I/O pins and are fairly low power as well.To drive the display, you will need 3 to 5 digital output pins (depending on whether you want to manually control the chip select and reset lines). Another pin can be used to control (via on/off or PWM) the backlight.To make things easy for you, we"ve written a nice graphics library that can print text, pixels, rectangles, circles and lines!The library is written for the Arduino but can easily be ported to your favourite microcontroller.

In the previous tutorial I showed how to build a weather station using DHT11 and BMP180 with an Arduino. However, the project has a downside which is the power consumption of the 16X2 LCD. If we were building a battery powered project with the desire to last for several weeks and probably several months, like a weather station for instance, then we’ll have to replace the LCD keypad shield from the previous tutorials and go for something like the low powered Nokia 5110 84×84 LCD display. In this tutorial I will be showing you how to drive this display with the Arduino and thus build projects with longer battery life.

Since we are just going to drive the display we won’t be needing sensors for this tutorial, however we will need the components listed below which include the Nokia 5110 itself and we will show how to drive the display using an Arduino board.

The Nokia 5110 display is basically a graphic LCD display useful for a lot of applications. It was intended originally to be used as a screen for cell phones and was used in lots of mobile phones during the 90’s. This display uses a low powered CMOS LCD controller/driver PCD8544, which drives the graphic display of size 84×48. It is very cheap and costs about 3$. You can get one here.

The Nokia 5110 LCD can display text, graphics as well as bitmaps. When this display is fully lit, it draws about 10mA but with the backlight off, it draws as low as 0.4mA. The power consumed by this display is very low compared to that of the keypad LCD shield used in the previous tutorial. I will be using the Arduino Mega for this tutorial as usual and you can buy one here. You can also buy jumpers, breadboards and power bank which you will be needing for this tutorial.

Before we start writing the code for this project, first we need to download the 5110 LCD graph library that was made by rinky-dink electronics. The library does most of the heavy lifting and makes it easy for us o use the LCD. Click here to visit the download page and then download the LCD5110_graph zip file. When done, unzip the file to your preferred location and then rename the unzipped folder to something simple like “LCD5110”. Copy and paste this folder in your arduino library folder, then run your arduino IDE.

Click on the file, then on examples and then click on LCD5110. Since we are using the Arduino Mega, under the LCD5110 drop down click on Arduino (AVR) and the open up the LCD graph demo file.

In the code we only have to change a few things. we can see from the comment section above that the RST pin of the display was connected to pin 11 but in our case we connected this pin to pin 12 of the Arduino Mega. We also have to change the CS from pin 12 to 11.

The first line after the comment section, the LCD5110 library was included and after that a myGLCD object was created with the numbers being the pins to which the LCD is connected. The last two values in the myGLCD object is the RST and CS values which has been changed as explained initially.

with this done, we move to the setup function. In the setup function, the InitLCD method is used to initialize the display and this method takes in a parameter for the display contrast. The contrast value is between 0-127 and since we didn’t pass in any value the default value which is 70 will be used. Next, the setFont method is called which sets smallFont as the display font style is called and lastly, the randomSeed function which is used to initialize the random number generator using analogRead on an unconnected pin as a random input.

In the loop function, on the first line the screen buffer is cleared using the clrScr method. The drawBitmap method was used to draw the arduino logo and this logo is placed in the screen buffer when the method is called. The update method is used to copy the screen buffer to the screen then we give it a delay of 2 seconds before clearing the screen buffer again.

Most of the functions used in the project have names that are self-explanatory like myGLCD.drawLine needs no explanation for instance as its clear the function draws a line.

Here is the full code for this project. Its an example from the Library named LCD5110_Graph_Demo and how to get to it has been described at the beginning of this section.

This is a monochrome LCD module comprised of 84x48 pixels that can be used to display rich graphics and text content. Though it"s an industrial module, this LCD display is extremely easy to use. This module is a revision that accepts 3-5v input. So no extra level shifter is needed. To have full control, you just need 5 pins. and as a classic display module among open source communities.

It uses the PCD8544 controller, which is the same used in the Nokia 3310 LCD. The PCD8544 is 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 in a single chip, including on-chip generation of LCD supply and bias voltages, resulting in a minimum of external components and low power consumption. The PCD8544 interfaces to microcontrollers through a serial bus interface.

Can use conductive glue to connect the module to the printed board, without cables. The metal hooks on the module can fix the module on the printed board, which is very easy to install and replace.

The name of this product itself is enough to explain its origin. Yes of course !!! this LCD module was used in old Nokia 5110/3310 cell phones.

Remember the pre-iPhone days when cell phones had buttons and you only touched that tiny black and white screen if you needed to clean it? Nokia used these little LCDs in their 3310 and 5110 cell phones.

Thanks to the PCD8544 controller’s versatility, it includes on-chip generation of LCD supply and bias voltages which results in low power consumption making it suitable for power sensitive applications. In a normal state, the LCD consumes as low as 6 to 7mA only.

As per datasheet, this chip operates in the range of 2.7 to 3.3 V and has 3v communication levels. So, for any 5V logic microcontroller like Arduino, some sort of logic level shifting is required (otherwise display may get damaged).

If you want to change the backlight of the LCD, just remove the LCD off the board by pushing the metal clips at the back side. When the screen comes off, you will notice the four LEDs soldered around the edges of the display. Just replace the LEDs with desired color LEDs.

There are many versions of these LCD displays that don’t come with any current limiting resistor. This means you have to be careful while connecting power supply to it. As a precautionary measure, you can place a 330Ω current limiting resistor in series with the ‘Backlight’ pin.

The PCD8544 LCD driver has a built-in 504 bytes Graphic Display Data RAM (GDDRAM) for the screen which holds the bit pattern to be displayed. This memory area is organized in 6 banks (from 0 to 5). Each bank contains 84 columns/segments (from 0 to 83). And each column can store 8 bits of data (from 0 to 7). That surely tells us we have

RST pin resets the display. It’s an active low pin meaning; you can reset the display by pulling it low. You can also connect this pin to the Arduino reset so that it will reset the screen automatically.

BL(Backlight) pin controls the backlight of the display. To control its brightness, you can add a potentiometer or connect this pin to any PWM-capable Arduino pin.

Connections are fairly simple. As we are implementing software SPI, we have flexible pin options. You can connect data transmission pins to any digital I/O pin. In our case the serial clock(CLK), serial data(DIN), data/command(DC), chip enable(CE) and reset(RST) pins are connected from pin 7 all the down to pin 3 on Arduino.

But unfortunately, the LCD has 3v communication levels, so we cannot directly connect these pins to the Arduino. We need some protection. This can be done by shifting levels.

Finally, The backlight(BL) pin is connected to 3.3V via 330Ω current limiting resistor. You can add a potentiometer or connect this pin to any PWM-capable Arduino pin, if you wish to control its brightness.

The PCD8544 LCD controller has flexible yet complex drivers. Vast knowledge on memory addressing is required in order to use the PCD8544 controller. Fortunately, Adafruit’s PCD8544 Nokia 5110 LCD library was written to hide away all the complexities so that we can issue simple commands to control the display.

Filter your search by typing ‘nokia’. There should be a couple entries. Look for Adafruit PCD8544 Nokia 5110 LCD library. Click on that entry, and then select Install.

This will give you complete understanding about how to use the Nokia 5110 LCD display and can serve as the basis for more practical experiments and projects. Try the sketch out and then we will dissect it in some detail.

The sketch starts by including three libraries viz. SPI.h, Adafruit_GFX.h and Adafruit_PCD8544.h. Next, we need to create an LCD object. This object takes 5 parameters and specifies which Arduino pins are connected to the LCD’s CLK, Din, D/C, CE and RST pin. We also defined rotatetext variable which will make sense a little later.

In setup function: we need to initialize the LCD object using begin() function. We also need to set the contrast of the display using setContrast(value) function with value can be anywhere between 0-100. However, value between 50-60 gives great results.

In order for the library to perform extremely fast mathematical operations on the screen buffer (more than 100 frames per second), calls to the print functions do not immediately transfer the contents of screen buffer to the PCD8544 controller. A display() command is required to instruct the library to perform the bulk transfer from the screen buffer in the ATmega328P to the internal memory of the PCD8544 controller. As soon as the memory is being transferred, the pixels corresponding to the screen buffer will show up on the LCD display.

Numbers can be displayed on the LCD display by just calling print() or println() function. An overloaded implementation of these functions accepts 32-bit unsigned int, so you can only display numbers from 0 to 4,294,967,295.

This last example shows how to draw bitmap images to the Nokia 5110 LCD Display. This is useful for creating splash screens of company logos, making sprites or just creating fun graphics for displaying information. Copy the following code, paste it into the Arduino IDE and click upload.

To show bitmap image on the Nokia 5110 LCD display we need to call drawBitmap() function. It takes six parameters viz. Top left corner X coordinate, top left corner Y coordinate, byte array of monochrome bitmap, width of bitmap in pixels, height of bitmap in pixels and Color.

But, before we can call the drawBitmap() function, we first need an image to draw. Remember, the screen resolution of Nokia 5110 LCD display is 84×48 pixels, so images larger than that will not display correctly. To get a correctly sized image, you can use your favorite drawing programs like Inkscape, Photoshop, Paint, etc., setting the canvas size to 84×48 pixels.

Once you have a bitmap, it’s time to convert it into an array that the PCD8544 controller can understand. This can be done using two ways: Online method using image2cpp and Offline method using LCD Assistant.

There’s an online application called image2cpp – http://javl.github.io/image2cpp/ which can convert your image into an array. Image2cpp is newer and much more powerful than LCD Assistant (later solution). It will allow you to:

The dimensions of your image will populate in Canvas size option under Image settings. If you have selected bigger image than 84×48, change it to 84×48 and select proper Scaling option. You can view the output in Preview section.

Once you are satisfied with the outcome, you can proceed generating the data array. Simply select Code output format as Arduino Code and click on Generate code button.

There’s another application called LCD assistant – http://en.radzio.dxp.pl/bitmap_converter/which can convert your bitmap image into data array. It’s not as powerful as image2cpp but still popular among hobbyists.

To start with, you need to convert you image into 84×48 1-bit monochrome bitmap. You can use your favorite drawing programs like Inkscape, Photoshop, Paint, etc. to do it, just like we did in MS paint.

Wiring: The Nokia LCD uses a serial interface for displaying images and text. This interface works very well with the SPI interface on the Teensy 2.0. Please be aware that the Teensy 2.0 is by default a 5V system while the Nokia module is 3.3V. You can either modify the Teensy to be 3.3V via the information below or insert a logic level shifting circuit in between the line. In this example we have already modified the Teensy to be 3.3V

After wiring the unit, you can download the C example code below. This code is tested to compile via avr-gcc under Windows and Linux. You may need to install the avr-gcc compiler prior to using these files. A pre-compiled .hex file is included for rapid use. There is a nokia5110.h and nokia5110.c file included in the example. The code initialized SPI on the Teensy 2.0 and displays a string of characters. The Nokia 5510 is a graphics LCD so to display text, the program also includes a bitmap that was used to create the font used to display text to the screen.
