arduino 1.8 tft display in stock
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.
Download each library and unzip the folders. Rename them to "Adafruit_ST7735" and "Adafruit_GFX" and place each folder inside your Arduino Libraries folder. I"ve attached a screenshot of the libraries in the correct folder. Once installed, you are ready to operate the screen! Inside the Adafruit ST7735 library is a file called graphicstest.ino which you can upload to your Arduino and it will run through a number of functions that draw objects to the screen. However, this file will need some altering to adapt the pins to your layout.
Alternatively, you can copy/paste the code below into the Arduino IDE and upload it. This is a modified version of Adafruit"s graphictest.ino, the primary difference being the assignment of pins. I also played with the code a bit to see what kind of functions there are. Let me know if you experience any issues with code. It worked fine for me./***************************************************
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 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.
This is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 396 source line and 162 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial Peripheral Interface (SPI), 8-bit/9-bit/16-bit/18-bit parallel interface.
The 1.8inch LCD uses the PH2.0 8PIN interface, which can be connected to the Raspberry Pi according to the above table: (Please connect according to the pin definition table. The color of the wiring in the picture is for reference only, and the actual color shall prevail.)
ST7735S is a 132*162 pixel LCD, and this product is a 128*160 pixel LCD, so some processing has been done on the display: the display starts from the second pixel in the horizontal direction, and the first pixel in the vertical direction. Start to display, so as to ensure that the position corresponding to the RAM in the LCD is consistent with the actual position when displayed.
Note: Different from the traditional SPI protocol, the data line from the slave to the master is hidden since the device only has display requirement.
Framebuffer uses a video output device to drive a video display device from a memory buffer containing complete frame data. Simply put, a memory area is used to store the display content, and the display content can be changed by changing the data in the memory.
If you need to draw pictures, or display Chinese and English characters, we provide some basic functions here about some graphics processing in the directory RaspberryPi\c\lib\GUI\GUI_Paint.c(.h).
Set points of the display position and color in the buffer: here is the core GUI function, processing points display position and color in the buffer.
The fill color of a certain window in the image buffer: the image buffer part of the window filled with a certain color, usually used to fresh the screen into blank, often used for time display, fresh the last second of the screen.
Display time: in the image buffer,use (Xstart Ystart) as the left vertex, display time,you can choose Ascii visual character font, font foreground color, font background color.;
Note: Each character library contains different characters; If some characters cannot be displayed, it is recommended that you can refer to the encoding set ro used.
The first parameter is a tuple of 2 elements, with (40, 50) as the left vertex, the font is Font2, and the fill is the font color. You can directly make fill = "WHITE", because the regular color value is already defined Well, of course, you can also use fill = (128,255,128), the parentheses correspond to the values of the three RGB colors so that you can precisely control the color you want. The second sentence shows Micro Snow Electronics, using Font3, the font color is white.
For the screen, if you need to draw pictures, display Chinese and English characters, display pictures, etc., you can use the upper application to do, and we provide some basic functions here about some graphics processing in the directory STM32\STM32F103RB\User\GUI_DEV\GUI_Paint.c(.h)
Image buffer part of the window filling color: the image buffer part of the window filled with a certain color, generally as a window whitewashing function, often used for time display, whitewashing on a second
Display time: in the image buffer,use (Xstart Ystart) as the left vertex, display time,you can choose Ascii visual character font, font foreground color, font background color.

The TFT display is a kind of liquid crystal LCD that is connected to each pixel using a transistor and it features low current consumption, high-quality, high-resolution and backlight. This 1.8-inch full color LCD has a narrow PCB screen. The resolution is 128×160 pixels and it has a four-wire SPI interface and white backlight. The driver is ST7735R.
Spice up your Arduino project with a beautiful small display shield . This TFT display is small (1.8" diagonal) bright (4pcs white-LED chips) and colorful (18-bit 262,000 different shades)! 128x160 pixels with individual pixel control.
The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Due/Mega 2560).
This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.
Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!
If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.
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):
