1.8 serial spi tft lcd module display arduino pricelist

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

Hi guys, welcome to today’s tutorial. Today, we will look on how to use the 1.8″ ST7735  colored TFT display with Arduino. The past few tutorials have been focused on how to use the Nokia 5110 LCD display extensively but there will be a time when we will need to use a colored display or something bigger with additional features, that’s where the 1.8″ ST7735 TFT display comes in.

The ST7735 TFT display is a 1.8″ display with a resolution of 128×160 pixels and can display a wide range of colors ( full 18-bit color, 262,144 shades!). The display uses the SPI protocol for communication and has its own pixel-addressable frame buffer which means it can be used with all kinds of microcontroller and you only need 4 i/o pins. To complement the display, it also comes with an SD card slot on which colored bitmaps can be loaded and easily displayed on the screen.

The schematics for this project is fairly easy as the only thing we will be connecting to the Arduino is the display. Connect the display to the Arduino as shown in the schematics below.

Due to variation in display pin out from different manufacturers and for clarity, the pin connection between the Arduino and the TFT display is mapped out below:

We will use two libraries from Adafruit to help us easily communicate with the LCD. The libraries include the Adafruit GFX library which can be downloaded here and the Adafruit ST7735 Library which can be downloaded here.

We will use two example sketches to demonstrate the use of the ST7735 TFT display. The first example is the lightweight TFT Display text example sketch from the Adafruit TFT examples. It can be accessed by going to examples -> TFT -> Arduino -> TFTDisplaytext. This example displays the analog value of pin A0 on the display. It is one of the easiest examples that can be used to demonstrate the ability of this display.

The second example is the graphics test example from the more capable and heavier Adafruit ST7735 Arduino library. I will explain this particular example as it features the use of the display for diverse purposes including the display of text and “animated” graphics. With the Adafruit ST7735 library installed, this example can be accessed by going to examples -> Adafruit ST7735 library -> graphics test.

The first thing, as usual, is to include the libraries to be used after which we declare the pins on the Arduino to which our LCD pins are connected to. We also make a slight change to the code setting reset pin as pin 8 and DC pin as pin 9 to match our schematics.

Next, we create an object of the library with the pins to which the LCD is connected on the Arduino as parameters. There are two options for this, feel free to choose the most preferred.

Next, we move to the void setup function where we initialize the screen and call different test functions to display certain texts or images.  These functions can be edited to display what you want based on your project needs.

The complete code for this is available under the libraries example on the Arduino IDE. Don’t forget to change the DC and the RESET pin configuration in the code to match the schematics.

Uploading the code to the Arduino board brings a flash of different shapes and text with different colors on the display. I captured one and its shown in the image below.

That’s it for this tutorial guys, what interesting thing are you going to build with this display? Let’s get the conversation started. Feel free to reach me via the comment section if you have any questions as regards this project.

To interface TFT LCD Display with Arduino, for designing custom HMI TFT LCD Display provide rich colours, detailed images, and bright graphics with their full-colour RGB mode it comes in different pixels 128 x 160 pixels, 320×240 pixels and many more.

In this tutorial, we’ll interface the 1.8 TFT LCD display with Arduino Uno. You’ll learn how to interface the TFT LCD with Arduino to write text on this LCD. This tutorial presents the coding, wiring diagram and components list required for the LCD display.

Creating an interface between the user and the system is very important. This interface can be created by displaying useful data, and menus. There are several components to achieving this. LEDs, 7-segments, OLEDs, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, and the type of user interaction.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. In the case of Arduino, the processor frequency is low. So it is not possible to display complex and high-speed motions. Therefore, full-colour TFT LCDs can only be used to display simple data and commands. This TFT has 128 x 160 pixels. 1.8 TFT display can load images from an SD card. It has an SD card slot at the back. You can see the front and back views of the TFT LCD in the figures below.

TFT is an abbreviation of “Thin Film Transistor”. It has transistors made up of thin films of Amorphous silicon. It serves as a control valve to provide an appropriate voltage onto liquid crystals for individual sub-pixels. The working principle is very simple the TFT LCD composes of many pixels that can emit light of any colour. The desired image achieves by controlling each pixel to display the corresponding colour. In TFT LCD, the backlight technology is generally used. In order to accurately control the colour and brightness of each pixel, it is necessary to install a shutter-like switch after each pixel. When the “blinds” are opened, light can pass through them. When the shutters are closed, light cannot pass through them.

Connect your PC to Arduino and open Arduino IDE. For the very first steps, you can refer to Connecting Windows PC with Arduino tutorial. You can get the .ino code and libraries from my download area with the following link:

This is the section before setup which uses for globe variables defining and libraries additions. TFT.h is the library for TFT LCD Display and uses for writing and drawing on the display. The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library.

This is the setup section in which Serial.begin(9600) initialize. TFTscreen.begin() is use to initialize the library. TFTscreen.background(0, 0, 0) is use to customize the screen background color here TFTscreen.background(0, 0, 0) means the background colour is black. TFTscreen.setTextSize(2) is use to set the font size.

In the loop section first, we will print the “Hi_peppe8o!” in the centre of the LCD and this will be in three different colours (Red, Green, Blue) you can choose any colour using the different colour codes. After 300 milliseconds a straight line will be displayed, after 300 milliseconds a square will be displayed, after 300 milliseconds a circle will be displayed, and after 300 milliseconds screen will be black/ erase and these all shapes and the text will be repeated in the void loop.

The LCD displays the text of “Hi_peppe80” and after that displays the line, square, and circle and then erases everything after completing this sequence. The command used for clearing all the data is TFTscreen.background(0,0,0):

This Bare Basic deals with connecting an Arduino with a breakout, serial SPI interfaced, 160×128 pixel color TFT display with a screen diagonal of 1.8 inch. The controller chip is a ST7735S.

The Sitronics ST7735 is a versatile display controller chip used to drive affordable, Arduino compatible TFT screens with moderate dimensions (1.8 inch display diameter; 160×128 pixels; 16-bit color). Displays with this chip can be applied as output color graphics / text display in an Arduino environment. An interesting library written by Adafruit exits that provides sufficient tools to create colorful, attractive presentation of data.

Once an Arduino has collected and manipulated data, display of the output is obvious. Reporting can be arranged via the Arduino IDE and Serial Monitor, but in this situation the Arduino must be connected to a computer while there is no way to directly produce graphical output. A separate display can be very handy for graphical data display and is especially recommended in standalone applications.

Displays for the Arduino are available in all kinds and price classes. I distinguish three groups: LCD, OLED and TFT. Well known is the monochrome LCD display with a blue or green background, usually with two lines of 16 characters or 4 lines of 20 characters, with each ‘character’ created in its own 8×5 pixel matrix. These LCD displays are good for displaying short messages or numerical values while they lack graphical capabilities and colors. Special LCD displays are the 128×64 monochrome numerical/graphical LCD display whose library offers a few primitive graphics, and the Nokia 5110 84×48 LCD display with a PCD8544 controller. LCD displays do not offer colors other than background versus character.

Figure 1: 1.8 inch 160×128 color TFT display with SPI interface on a breakout board (ST7735 compatible). Left: simple sketch showing text mode; right: graphics test mode.

A special kind of LCD is the OLED display. This family includes small, programmable graphical displays (64×32 or 128×32 pixels) in monochrome or full color.

More versatile than the LCD displays, as well as larger, are TFT displays (fig 1). These are capable of graphics and a spectrum of colors (65,536 up to 256,000 colors) to the degree that they support realistic display of color pictures. TFT displays can be bought in a dazzling array of sizes, resolution, interfaces and prices.

TFT displays for the Arduino microcontroller boards can be accessed via an 8-bit parallel data interface – fast but consuming at least 8 pins of the Arduino. An alternative is the serial SPI interface which needs only five pins.

See the Table below, and Figure 2. Here, an Arduino Nano is used whose pin layout is identical to that of an Arduino Uno. Figure 2 shows the details of the wiring.

Figure 2: Wiring of the 160×128 SPI 1.8 inch color TFT display. Note that more expensive displays have a voltage level shifter on board. This makes it possible to connect VCC with 5V instead of 3.3V as in this clone situation.

Here is a no-frills sketch that does what is needed; display some message on the display, with some color and two graphic element (one visible: the frame rectangles and one invisible: the rectangles filled with the same color as the background used to wipe out text).

ST7735 controller based TFT displays are very handy displays for use in Arduino applications. One typical application is a standalone weather station built around an Arduino platform and decorated with temperature, humidity and barometric pressure sensors. The ST7735 is less sophisticated as the bigger parallel TFT screens but displays based on this chip form a nice intermediate between the ‘big’ TFTs and the basic LCD displays.
