LCD Nokia 5110 + sistem Arduino

by
[ [ images, codes & links ] ]

The Nokia 5110 display has long been an Arduino Hobbyist favorite and a search of the internet will show that there are tons of different ways to drive this device.

There are a few varieties of this module are out there.   Mine are labeled as you see below.   Others should work just fine with this tutorial if you map your pins correctly.

Remember,  VCC is 3.3 Volts.   The LIGHT Control can use pulse width modulation through a 330 ohm resistor.

Untuk penggunaan LCD Nokia 5110, salah satu pustaka yang bisa dipergunakan adalah u8glib (atau versi yang lebih baru u8g2). Sebagai contoh untuk uji coba, dapat diikuti kode program dari: henrysbench.capnfatz.com berikut:

// Henry's Bench
// Arduino Nokia 5110 U8Glib Tutorial


#include "U8glib.h"

 

#define backlight 11
 
//Delcare the display and assign the pins
 
//U8GLIB_PCD8544 u8g(8, 4, 7, 5, 6);  // CLK=8, DIN=4, CE=7, DC=5, RST=6
 
 
U8GLIB_PCD8544 u8g(8, 4, 7, 5, 6);  // CLK=8, DIN=4, CE=7, DC=5, RST=6

 
void draw() {
 
  u8g.setFont(u8g_font_profont11);  // select font
  u8g.drawStr(0, 15, "Nokia 5110..");  // put string of display at position X, Y
  u8g.drawStr(29, 35, "HELLO!!!!");
  
  
}
 
void setup() 
{
  // Set Backlight Intensity
  // 0 is Fully bright
  // 255 is off
  analogWrite(backlight, 20);
  //
  // Enter the U8Glib Picture Loop
  //
  
}
 
void loop() 
{ 
 u8g.firstPage(); 
  do 
  {
    draw();
  } while( u8g.nextPage() ); 
  
}

Salah satu pustaka/library yang umum dipergunakan untuk LCD Nokia 5110 adalah pustaka  yang dikeluarkan oleh Adafruit. Terdapat dua bagian pustaka untuk lcd ini, satu adalah untuk driver hardware dan satu untuk pustaka grafik.

Urutan pin LCD 5110 pada produk Adafruit bisa jadi tidak sama dengan urutan pin LCD 5110 yang bisa dibeli di pasaran lokal (impor dari China). Meskipun begitu, pustaka dapat dipergunakan dan berfungsi secara normal.

 

Testing

You can find our Nokia Display Arduino library on github. To install it, click this button to download the compressed ZIP file then install it. This guide will help you with the install process if you have never installed an Arduino library.

Then you’ll have to do the same for the Adafruit GFX Graphics core library, available from github. Click the button to download it. Then install Adafruit_GFX just like the library you’ve done except this time name it Adafruit_GFX, etc.

Restart the Arduino software. You should see a new example folder called Adafruit_PCD8544 and inside, an example called pcdtest. Open up that sketch and upload it to your Arduino. You should see the example test sequence.

Graphics Library

We have a ready to go basic graphics library that has primitives for bitmaps, shapes and text. You can probably do everything you want using it. Because of the way the display works we need to buffer the entire display in ram which is 84×48 bits (504 bytes). However, screen updates are very fast.

For more details about the Adafruit GFX library, please visit http://learn.adafruit.com/adafruit-gfx-graphics-library – it supports lines, rectangles, roundrects, circles, text of different sizes etc.

Note that since this display is MONOCHROMATIC it only supports two colors: BLACK or WHITE. BLACK is a displayed dot and WHITE is for erasing pixels

Dont forget, after drawing anything to the screen, call display() to write it out to the LCD!

Downloads

Our PCD8544 (Nokia 5110) LCD display Arduino library is on github which comes with example code. This library uses 1/2 Kbytes of RAM since it needs to buffer the entire display but its very fast! The code is simple to adapt to any other microcontroller.

You’ll also need to get the Adafruit GFX Graphics core library which can print text, bitmaps, pixels, rectangles, circles and lines, also available on github.

The PCD8544 datasheet tells you all about what the display can do.

  U8glib Example Overview:
    Frame Buffer Examples: clearBuffer/sendBuffer. Fast, but may not work with all Arduino boards because of RAM consumption
    Page Buffer Examples: firstPage/nextPage. Less RAM usage, should work with all Arduino boards.
    U8x8 Text Only Example: No RAM usage, direct communication with display controller. No graphics, 8x8 Text only.

  U8glib Example Overview:
    Frame Buffer Examples: clearBuffer/sendBuffer. Fast, but may not work with all Arduino boards because of RAM consumption
    Page Buffer Examples: firstPage/nextPage. Less RAM usage, should work with all Arduino boards.
    U8x8 Text Only Example: No RAM usage, direct communication with display controller. No graphics, 8x8 Text only.

baghayi/Nokia_5110

A little bit of a history:

Nokia 5110 LCD was meant to be used in one of my projects yet to fail. Not having thoroughly read its datasheet, started looking for drivers and libraries to get it up and running as quickly as I could, but failed dramatically.

Target Platforms

Currently, it is written to be used with Arduino platform.

How to use it, then?

First, you need to copy or clone this library into your Arduino’s libraries folder so that you can address it in your Arduino programs.

To do that, you can either download and move this library into libraries folder, or if you have Git installed in your computer then you can go to libraries folder and clone this library into libraries folder (which is a way of downloading).

In order to download this library, there is a Download button in this page, somewhere :), by clicking on it you can download the library, then unzip and finally move it to libraries folder.

To clone it, you open a terminal or console window in the libraries folder then type git clone REPO_URL (replace REPO_URL, with repository’s link which is located in this page somewhere), then hit enter and after it is completly downloaded, you are good to go.

Then, you need to include this library in your program in order to use it. To achieve this, add this piece of code in top of your program: #include "Nokia_5110.h"

Now, its time to instantiate Nokia_5110 class to have access to its APIs. Which is also a way of telling the driver which pins of LCD is associated with I/O pins of Micro-controller. How do we do that? easy:

In setup function of your program, or outside of it, create a variable to hold Nokia_5110 class’ object:

Nokia_5110 lcd = Nokia_5110(RST, CE, DC, DIN, CLK);

in this case variable is called lcd. And as you can see, Nokia_5110’s constructor needs 5 parameters.

  • RST is for lcd’s reset pin.
  • CE is for lcd’s chip enable pin.
  • DC is for lcd’s Command/Data pin.
  • DIN is for lcd’s data in pin.
  • CLK is for lcd’s clock pin.

You need to pass the constructor, digital pin numbers of arduino to which LCD pins are connected.

At this point, if everything goes as planned, you should be able to access this driver’s APIs (meaning, being able to call its methods, functions) in you program.

So, let me list and explain each and every API availabe in your program by this driver (Nokia_5110.h).

Public APIs

  • void setContrast(unsigned short value);This method allows us to change LCD’s contrast.It accepts a value between 0 and 127 (0 >= value <= 127) as its parameter.By default, in the driver, contrast value is set to 60. If it is not satisfactory, you can easily change it using setContrast method.
  • void setTemperatureCoefficient(unsigned short value);This method allows us to set temperature coefficient. As stated in the datashee, in lower temperatures, LCD’s controlling voltage needs to be increased to make it work properly. Which is what this method is for. (Please refere to PCD8544 driver’s datasheet for more information on this topic.)This method accepts a value between 0 and 3 (0 >= value <= 3) as its parameter.
  • void print(value);
  • void print(value, format);
  • void println(value);
  • void println(value, format);These methods lets us display information on the LCD. It prints data that is passed to its parameter on the LCD.At the moment, English upper and lower characters are supported. Numbers and some other characters are supported as well. For the list of supported characters please refer to the src/Font.h file.Note: In case of unknown characters, question mark (?) will be displayed, instead.println method works exactly like print method, only with the exception of jumping to the next line after printing the last character.Since this driver uses built-in Print class, which is what provided by the Arduino, they work exactly like print and println methods in Serial and LiquidCrystal libraries.They can accept different data types, such as string, char, integers and etc.For more information on these methods parameters, check out this link: https://www.arduino.cc/en/Serial/Print
  • void clear();Clears the display and then moves the cursor to the first row and column.
  • void clear(position inRow, position fromColumn, position toColumn);This method is for when you only want to clear a portion of the LCD.First parameter, inRow accepts a value between 0 and 5 as an indication of the row number. Second parameter, fromColumn is the beginning of a portion you want to start clearing from. And the third parameter, toColumn is the end of the column, you want to be cleared. So, from the start to the end of the specified column, in the specified row, will be cleared.Second and third parameter accepts a value between 0 to 83.Note that, third parameter, toColumn, is included in the clearing process, and that column’s data will be removed as well.Note: After clearing process is done, cursor will be moved to the fromColumn column. So that you would not need to manually set the cursor after clearing, if all you want is to clear and print some other data in the place of the previous one.
  • void setCursor(position x, position y);This method is for specifying cursor position. Like when you want to write some characters on the middle of the screen, you can use this method to jump to the middle of the screen, by passing it the exact location, and then you can start printing characters right there.first parameter, x, accepts a value between 0 and 83 (column). and second parameter, y, accepts a value between 0 and 5 (row).
  • void setDisplayMode(display_mode mode);As stated in the datasheet, LCD has four different display modes. One is for normal mode. One for blank display. One for turning all display’s segments on. And the last one is inverse video.This method as its parameter expects a hex value. But it is not nice, is it? :D. For ease of use, driver has four constants defined with respective display mode hex values as their values. So you only need to pass those constant as parameter value instead of hex values.Defined constants for display mode are as follows:

Display_Mode::BLANK is for a blank display.

Display_Mode::NORMAL is normal mode, which by default is set by the driver.

Display_Mode::ALL_SEGMENTS_ON for turning all segments (pixels) on.

Display_Mode::INVERSE_VIDEO In normal mode, you have black text in a white background. This mode is the inverse of normal mode (white text in a black background).

  • void setBiasSystem(mux_rate rate);This method is for system biasing. For setting the view angle. By default by the driver it is set to Mux_Rate::FORTY, but you can change it any time you want. Not to mention that by changing it, you may also need to change the contrast value of the display.Like setDisplayMode you need to pass a hex value as its parameter, but for ease of use, for all of available biasing hex values, constant values is defined. List of constants are as follows:

Mux_Rate::HUNDRED

Mux_Rate::EIGHTY

Mux_Rate::SIXTY_FIVE

Mux_Rate::FORTY_EIGHT

Mux_Rate::FORTY

Mux_Rate::TWENTY_FOUR

Mux_Rate::EIGHTEEN

Mux_Rate::TEN

For more information on this topic, please refer to datasheet.

About the development of this driver

There are things I would love to add to this driver, but until I need them in my projects I might not work on them, so appologies in advance 😀 .

Some of the thins are:

  • adding comma (,) to the font file. Which I had forgotten to do so when developing this driver.
  • returning current cursor position after printing, from the print and println methods. So if you need to move a bit further in a row (meaning moving cursor in the X position) and then print new characters, you wouldn’t have to guess what column to set the cursor. You could easily add some random (:D) number to the current cursor position to avoid printing on the already printed charcters. and probably a new method for separately requesting cursor position without the need of calling print methods.
  • Supporting right to left languages.
  • Bigger font sizes.
  • And then, living happily ever after.

Library: LCD5110_Basic

These displays were used in old Nokia 5110/3310 cell phones. It is a 84×48 pixel monochrome LCD display. These displays are small, but very readable and come with backlight. This display is made of 84×48 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 5 digital output pins. Another pin can be used to control (via on/off or PWM) the backlight, but the library has no support for this function.

The display driver is a PCD8544 chip, and it runs at 3.3V so you will need a 3V supply handy. Logic levels must be 3V to prevent damage so you must use some kind of levelshifter.

This library uses an SPI-like software protocol and does require exclusive access to the pins used. You will not be able to share pins with other SPI devices.
