arduino 1.8 tft display tutorial factory

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.

I got a few random displays of several types and it was, um, challenging to get them working. Now each has a minimum test program associated with it I can use as a starting point.

I have found the really cheap displays to function, but seem clearly to be factory seconds, like the OLED I had that aged out waaay too soon. And the touch screen that needed more than a touch alla time.

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./***************************************************

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (4.3" diagonal) bright (8 white-LED backlight) and colorfu 480x272 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default and a optional capacitive touch panel with controller FT5206 attached by default, so you can detect finger presses anywhere on the screen and doesn"t require pressing down on the screen with a stylus and has nice glossy glass cover.

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.

A number of display devices like LEDs, 7-segments, character and graphic displays can be attached to microcontrollers to create an interface between the user and an electronic system for displaying data or controlling the system. Sometimes you may need to add colorful images or graphics to your project, that’s where the TFT color displays come in handy.

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 this tutorial we are going to show how to interface a 1.44″ TFT color display based on the ST7735 driver. It has 128×128 color pixels and can display full 16-bit color.

This is the type of display am using but they come with various pin configurations. However all the displays will have the major pins stated below and should be connected to the Arduino board as follows:

This TFT display uses 3.3V but comes with an on board voltage regulator therefore the VCC can be connected to the Arduino 5V. However for best practice it’s better to use the 3.3V.

Most code Libraries for this TFT ST7735 display with Arduino are programmed with the SDA and SCL pins connected to Arduino pins 11 and 13 respectively. Make sure you don’t change that order otherwise the display may not work.

There are a number of libraries that have been developed to run the TFT ST7735 color display using Arduino but I found the Adafruit-ST7735-Librarythe best to use. Make sure you have this library installed in your IDE.

tft.fillRoundRect(x,y,w,h,r,t); function draws a filled Rectangle with r radius round corners in x and y location and w width and h height and t color.

There are many other functions and commands which you can use to program the TFT color display but the above are the commonest. You will meet many more with practice.

Before we can write our personal code we need to first test the display using the already made code examples from the installed library. This is done by going to File>Examples>Adafruit ST7735 and ST7789 Library. Then you can select any of the examples and upload it to the setup to see if the display works fine.In the diagram below I have shown how to access the graphics test code.

This ST7735S 1.8" TFT Display features a resolution of 128×160 and SPI (4-wire) communication. Integrated with an SD card slot, it allows to easily read full-color bitmaps from the SD card. The module provides users with two wiring methods: pin header wiring and GDI (General Display interface). You can directly use an FPC cable to connect the display to any controller with GDI interface like FireBeetle-M0. Plug and play, easy to wire. Besides, the display supports low refresh rate and offers good display effect and strong versatility. It can be used in applications like sensor monitoring and alarm, Arduino temperature monitor, fan controller, etc.

This product is a breakout module that features SPI communication mode and onboard GDI interface, which could reduce the complexity of wiring. It can easily display the read content from the SD card.

The BasicTest.ino code shows us the basic display functions of the screen: text display, number display, drawing lines, drawing rectangles and other demos.

screen.drawXBitmap(/*x=*/(screen.width()-146)/2,/*y=*/(screen.height()-128)/2,/*bitmap gImage_Bitmap=*/gImage_XBitmap,/*w=*/146,/*h=*/128,/*color=*/0x0000);

screen.drawRGBBitmap(/*x=*/(screen.width()-146)/2,/*y=*/(screen.height()-128)/2,/*bitmap gImage_Bitmap=*/(const unsigned uint16_t*)gImage_RGBBitmap,/*w=*/146,/*h=*/128);

We covered the basics of accelerometer previously inUsing Arduino with Parts and Sensors – Accelerometer Part 1andUsing Arduino with Parts and Sensors – Accelerometer Part 2. Today we’ll be testing KX022-1020 accelerometer using TFT liquid crystal panel. We’ll discuss how to control the TFT LCD in more detail in the next article. In addition, we’ll further exploreArduino Create. For more information about Arduino Create, please refer back tothisarticle.

We’ll continue using Arduino Create Web Editor as we did in our lasttutorial. To add the library, you can upload the zip file by selecting it from “Libraries” on the left menu and clicking on “ADD ZIP LIBRARY.”

After adding the library, attach the accelerometer to the Sensor Shield (I2C I/F) and try running the sample program. The accelerometer should be set to 1.8V or 3.0V.

Now the sample program is working fine, let’s try to display the values on a 1.8 inch TFT LCD monitor. Although this TFT liquid crystal monitor has a resolution slightly smaller than 126 x 160 px, it’ll be quite useful when displaying numbers or letters with Arduino etc.

In the past, we used 7-segment LED to display numerical values only. But this time, I tried to display the graph along with the values obtained from the accelerometer.

When using the TFT monitor, the connection method and the library used in the program may be different depending on the specification of each TFT monitor. The TFT monitor used in this tutorial is a monitorSainSmart ST7735R. In addition to Arduino, the monitor is also compatible with Raspberry.

In order to use the monitor to run the program in Arduino, we’ll have to modify the downloaded library a little bit.We’ll go over how to control the TFT LCD in more detail in the next article. Once everything is set, you will be able to output numerical values in the monitor as shown in the video below:

In the next part, we’ll create a simple device using the same accelerometer and TFT monitor. We’ll show how to create graphs and display the values obtained from the accelerometer on the TFT monitor.

This tutorial introduces a powerful and versatile display module – the 1.8 Inch SPI TFT Color Display. This small yet mighty module packs a punch with its ability to display vibrant colors and high-resolution images. It is perfect for creating dynamic user interfaces and opens up many possibilities for different projects.

With the ease of interfacing it with an Arduino microcontroller, the possibilities are endless. This article will guide you through setting up this display module and how to harness its full potential. So, if you’re ready to take your projects to the next level, read on!

A color display module refers to a display monitor that is able to show a wide range of colors. They are wonderful for enhancing the user interface of any product by adding a fascinating element to it. They may be found in more advanced forms of mobile phones, tablets, computers, and digital picture frames.

First, you need to install Arduino IDE Software from its official website Arduino. Here is a simple step-by-step guide on “How to install Arduino IDE“.

Before you start uploading a code, download and unzip the following libraries at /Progam Files(x86)/Arduino/Libraries (default),in order to use the sensor with the Arduino board. Here is a simple step-by-step guide on “How to Add Libraries in Arduino IDE“.

my_lcd.Draw_Line(2+random(my_lcd.Get_Display_Width()-4),12+random(my_lcd.Get_Display_Height()-24),2+random(my_lcd.Get_Display_Width()-4),12+random(my_lcd.Get_Display_Height()-24));

my_lcd.Draw_Rectangle(2+random(my_lcd.Get_Display_Width()-4),12+random(my_lcd.Get_Display_Height()-24),2+random(my_lcd.Get_Display_Width()-4),12+random(my_lcd.Get_Display_Height()-24));

my_lcd.Draw_Round_Rectangle(2+random(my_lcd.Get_Display_Width()-4),13+random(my_lcd.Get_Display_Height()-26),2+random(my_lcd.Get_Display_Width()-4),13+random(my_lcd.Get_Display_Height()-26),5);

my_lcd.Draw_Triangle(2+random(my_lcd.Get_Display_Width()-4),12+random(my_lcd.Get_Display_Height()-24),2+random(my_lcd.Get_Display_Width()-4),12+random(my_lcd.Get_Display_Height()-24),2+random(my_lcd.Get_Display_Width()-4),12+random(my_lcd.Get_Display_Height()-24));

my_lcd.Draw_Bit_Map(my_lcd.Get_Display_Width()/2-1-((len/2)*4/3+1)*i, my_lcd.Get_Display_Height()/2-1-(len/2) my_lcd.Get_Display_Height()/2-1-(len/2) *i, 8, 6, buf, i*(len/6));

my_lcd.Fill_Round_Rectangle(my_lcd.Get_Display_Width()/2-1-62+1, my_lcd. my_lcd. Get_Display_Height()/2-1-40+1, my_lcd. my_lcd. Get_Display_Width()/2-1+62-1, my_lcd. my_lcd. Get_Display_Height()/2-1+40-1,5);

Once the code is uploaded, you should see “* Color TFT Display *” at the top center and “” at the bottom. Next, the display will show some animations. You can experiment with different values in the code to see how it affects the display.

Once all these functions are defined, the code enters the “loop” function. This function is where the magic happens! It starts by clearing the screen and then calls the “show_total_time” function, which runs all the other functions one after the other and measures how long it takes for the code to run. It then calls the “show_end” function, which displays the time it took for the code to run on the screen.

We hope you have found this Interfacing 1.8 Inch SPI TFT Color Display Module with Arduino Circuit very useful. If you feel any difficulty in making it feel free to ask anything in the comment section.

The 1.8″ display has 128×160 color pixels. Unlike the low cost “Nokia 6110″ and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display is a true TFT! The TFT driver (ST7735R) can display full 18-bit color (262,144 shades!). And the LCD will always come with the same driver chip so there’s no worries that your code will not work from one to the other.

The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. There is a microSD card holder on the back so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card.

The Adafruit 1.8” TFT LCD Breakout Board also features an EYESPI connector for a simpler connection to the LCD. EYESPI is a single 18-pin FPC used as a quick way to connect displays.

TFT Displays provide rich colors, detailed images, and bright graphics with their full-color RGB mode. TFT displays are perfect for applications including industrial instruments, coffee machines, automation, GPS navigator, energy control, and medical devices.

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.
