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.

3. What if Adafruit libraries are not displaying with the desired colors. This is a little hard to solve. Our suggestion, create a small function that display each color and note the number. Affordable electronics require a little more hacking, that"s all, it"s part of the fun. Check the following colors first, and adjust accordingly.

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.

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.

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.

Having a big Color TFT display for your Arduino Projects can make things much more impressive. Today I am going to show how to use the low cost 3.2″ inch Color TFT display with Arduino Mega and Arduino Due.

I always wanted to have a big display for my Arduino projects. So, a few weeks ago I decided to buy this 3.2 Inch color TFT display for Arduino Mega from Banggood.com because the price is so tempting! Less than 7$ for a 3.2’ color TFT display. With that price you can’t go wrong. Here’s the link.

The display has a resolution of 480×320 pixels and has an SD card adapter on the back. I haven’t used SD card functionality so far. I will try to use it in the future. If you look carefully you can see that the display also uses a 3.3V regulator so it works fine with 5V and 3.3V logic levels.

As you can see the connection with an Arduino Mega board is extremely easy. All you have to do, is to plug the display in, and load the sketch. I have also loaded the demo sketch on the Arduino Due and as you can see it works fine on an Arduino Due as well. Arduino Due, is much faster than the Arduino Mega. The demo sketch needs around 44 seconds to run on the Arduino Mega, and only 22 seconds on the Arduino Due. That’s a huge performance difference. Now let’s go to the computer in order to see what drivers we need in order to use the display with Arduino.

The display uses the HX8357C controller. Unfortunately, the UTFT library does not support it anymore. I am using other libraries to drive the display:

In this tutorial, we are going to interface a 3.5-inch TFT display with Raspberry Pi Zero Wdevelopment board. Although Raspberry pi zero itself has an HDMI output that can be directly connected to a Monitor, but in projects where space is a constrain, we need smaller displays. This TFT touch screen display can be easily interfaced to the Raspberry Pi to display the system console, movies, and images, as well as control a relay board and other devices at your fingertips. We’ve used software like MobaXterm or putty to connect to the PC remotely in past tutorials. Here, we are going to use MobaXterm software to install the required drivers for interfacing TFT display with Raspberry Pi Zero W.

This TFT LCD display has a 3.5-inch resistive touch screen display and is compatible with any hardware of the Raspberry Pi family. This 3.5" TFT display has 480x320 pixels with a 16-bit resolution and resistive touch option. It can fit directly on top of the Raspberry Pi Zero W board and gets powered from the Vcc pin, the display communicates through SPI protocol with the Pi. Additionally, you can also use the HDMI port on the Pi to connect it to another display as well. It is designed for Raspberry Pi Zero/Pi 2 /Pi 3 Model B / B+ and can also be used on other hardware platforms which have SPI interfaces. The highlights of this display module is that it supports plug and play without rebooting the Pi and the SPI speed runs as fast as 32MHz to support games and videos.

There are 26 pins in TFT RPi LCD display. It"s used to establish SPI communication between the Raspberry Pi and the LCD, as well as to power the LCD from the Raspberry Pi"s 5V and 3.3V pins. The description of pins is shown below.

It is very easy to connect Raspberry Pi Zero W with a 3.5” TFT LCD display. There are 40 pins on the Raspberry Pi Zero W, but only 26 pins on the LCD, so make sure you connect the pins to your Pi correctly. A strip of female header pins on the LCD will fit snugly into the male header pins. To establish the connection, simply align the pins and press the LCD on top of the Raspberry Pi zero W. When everything is in place, your Pi and LCD should look like the one given below.

It"s expected that your Raspberry Pi already has an operating system installed and can connect to the internet. If it is not then you can follow our previous tutorial Getting Started with the RASPBERRY PI ZERO W – Headless Setup without Monitor. It"s also assumed that you have access to your Raspberry Pi"s terminal window. In this tutorial, we are going to use MobXterm in SSH mode to connect it with Raspberry Pi Zero W.

Step-5: Now, restart your Raspberry Pi Zero W. When the Raspberry Pi Zero W restarts, you will see the boot information on the LCD display before the desktop appears, as shown below.

I would like to add one thing at the end of this tutorial that while doing this interfacing, I faced a problem related to OS. TFT display interfacing with Raspberry Pi Zero W was not working on Raspberry Pi OS LiteandRaspberry Pi OS with desktopbut when I used the Raspberry Pi OS with desktop and recommended software then TFT display interfacing with Raspberry Pi Zero W worked as expected.

This is how you can interface Raspberry Pi Zero W with a 3.5 inch TFT Raspberry Pi display. In our next tutorials, we are going to interface different sensors with Raspberry Pi Zero and you will see some amazing DIY projects using Raspberry Pi Zero W. I Hope you"ve enjoyed the project and learned something useful. If you have any questions, please leave them in the comment section below or use our forum to start a discussion on the same.

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 ST7789 TFT module contains a display controller with the same name: ST7789. It’s a color display that uses SPI interface protocol and requires 3, 4 or 5 control pins, it’s low cost and easy to use. This display is an IPS display, it comes in different sizes (1.3″, 1.54″ …) but all of them should have the same resolution of 240×240 pixel, this means it has 57600 pixels. This module works with 3.3V only and it doesn’t support 5V (not 5V tolerant).

The ST7789 display module shown in project circuit diagram has 7 pins: (from right to left): GND (ground), VCC, SCL (serial clock), SDA (serial data), RES (reset), DC (or D/C: data/command) and BLK (back light).

As mentioned above, the ST7789 TFT display controller works with 3.3V only (power supply and control lines). The display module is supplied with 3.3V (between VCC and GND) which comes from the Arduino board.

To connect the Arduino to the display module, I used voltage divider for each line which means there are 4 voltage dividers. Each voltage divider consists of 2.2k and 3.3k resistors, this drops the 5V into 3V which is sufficient.

The first library is a driver for the ST7789 TFT display which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “st7789” and install the one from Adafruit).

This is a low-cost but powerful TFT display that makes your project look awesome! The display has 240 x 240 pixels resolution, and its size is only 1.3inch. This allows you to display a high-quality picture, to make your project really cool.

The module interface is SPI, to make the display small the CS pin is not breakout, but you can still drive it without connecting a CS pin, here is a library working library for this particular display, to make it working properly, you also need to install Adafruit’s GFX library.

This is a small graphics library, specifically aimed at ATtiny microcontrollers, for the variety of small colour TFT displays available at low cost from suppliers like Adafruit, AliExpress, or Banggood:

It"s an updated version of my Tiny TFT Graphics Library. This latest version of the library supports both the classic ATtiny processors, such as the ATtiny85, and the new 0-series, 1-series, and 2-series ATtiny processors, such as the ATtiny402. Like the original library it allows you to plot points, draw lines, draw filled rectangles, and plot characters and text with an optional scale factor, in 16-bit colour.

This version adds the ability to plot outline rectanges, and outline and filled circles. I"ve included demo curve-plotting and histogram-plotting programs that adjust to fit any display.

This library supports TFT displays that use an SPI interface and require four pins to drive the display. This leaves one pin free on an 8-pin chip such as the ATtiny85 or ATtiny402. If you need more pins choose a larger chip, such as the ATtiny84 or ATtiny404.

Unlike my Compact TFT Graphics Library which uses standard Arduino SPI calls, this library uses direct I/O pin manipulations. This means that you can use any assignment of pins to the four I/O lines needed by the display, and makes it about twice as fast as one using SPI calls. I"ve also added support for some additional displays, so it now supports 16 different TFT displays.

So provided you set all the pins to their disabled state at startup, the display routines can simply toggle the appropriate pins to enable or disable them.

The differences between each family of processors are handled by constants to define the pin assignments, and preprocessor macros to define the bit manipulations. If you use the circuits given below you won"t need to change anything, apart from specifying which display you"re using.

The ClearDisplay() routine has been optimised further by realising that we don"t need to keep setting the mosi bit, since to clear the display it is always zero, so the routine only needs to toggle the sck bit the appropriate number of times. I"m grateful to Thomas Scherer for suggesting this.

This library will work with displays based on the ST7735 which supports a maximum display size of 162x132, or the ST7789 and ILI9340/1 which support a maximum display size of 320x240. It includes parameters for the following colour TFT displays:

* These Adafruit displays conveniently all have the same edge-connector layout, so you can make a prototyping board or PCB that will take any of them, such as my Universal TFT Display Backpack.

Some of the AliExpress displays include a LDO 3.3V regulator, but not logic-level translation, so I recommend only interfacing them to a processor running from 3.3V.

The Adafruit displays all include an LDO 3.3V regulator and logic-level translation, so can be safely interfaced to processors powered from either 5V or 3.3V.

On the AliExpress red 160x128 display you need to connect the backlight pin to Vcc to turn it on. This doesn"t seem to be necessary with the other displays.

The library will probably support other TFT displays that use the same ST7735, ST7789, ILI9340/1 driver chips, but you may need to experiment with the parameters to get the image scaled and centered correctly.

The display needs to be connected to the microcontroller via four I/O lines: MOSI, SCK, CS, and DC. You can use any pins for these, but they should all be in the same port. You need to specify the port pin numbers of the pins you are using at the start of the Tiny TFT Graphics Library listing.

The 33kΩ pullup resistor from the display"s CS pin is optional; it is only needed on the AliExpress displays, and holds the chip select high to prevent the display from flickering while programming the ATtiny85.

The different displays are catered for by seven constants which specify the size of the display, the offsets relative to the area supported by the display driver, whether the display is inverted, the rotation value, and the order of the colours; for example:

By default the parameters give the correct orientation assuming you"re using the display with the header pins along the top, except in the case of the larger displays which have the header pins along the shorter edge, in which case the header pins are assumed to be on the left.

To check or adjust the values for each display you can run the TestChart() program, which draws a one-pixel border around the display area, and plots a red "F" to show the orientation:

The library will probably support other TFT displays that use the same driver chips, but you may need to experiment with the parameters to get the image scaled and centered correctly.

The library includes basic graphics routines for plotting points and drawing lines. These work on a conventional coordinate system with the origin at lower left. For example, on the 80x160 display:

The TFT display provides a semiconductor switch for each pixel and each pixel is directly controlled by pulse. Therefore, each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display, but also can be accurately controlled. The color level is displayed to make the TFT LCD color more realistic, the brightness is good, the contrast is high, the layering is strong and the color is bright.
