2.4 tft lcd touch shield for arduino factory

In this tutorial, you will learn how to use and set up 2.4″ Touch LCD Shield for Arduino. First, you’ll see some general information about this shield. And after learning how to set the shield up, you’ll see 3 practical projects.

The role of screens in electronic projects is very important. Screens can be of very simple types such as 7 Segment or character LCDs or more advanced models like OLEDs and TFT LCDs.

One of the most important features of this LCD is including a touch panel. If you are about to use the LCD, you need to know the coordinates of the point you touch. To do so, you should upload the following code on your Arduino board and open the serial monitor. Then touch your desired location and write the coordinates displayed on the serial monitor. You can use this coordination in any other project.

To display pictures on this LCD you should save the picture in 24bit BMP colored format and size of 240*320. Then move them to SD card and put the SD card in the LCD shield. we use the following function to display pictures. This function has 3 arguments; the first one stands for the pictures name, and the second and third arguments are for length and width coordinates of the top left corner of the picture.

If you want to display pictures without using an SD card, you can convert it to code and then display it. You can display even several photos sequentially without delay to create an animation. (Check this) But be aware that in this case, Arduino UNO may not be suitable (because of low processor speed). We recommend using the Arduino Mega or Arduino DUE.

The 2.4 ” tft lcd touch screen shield for Arduino can be used in a number of applications. However many of the shields available on the market are cloned versions which usually give many hobbyists hard time to use because they do not work properly with the common libraries for running TFT displays.

If you try uploading any of the examples in the Adafruit_GFX library for example the “graphicstest”, the lcd will just give a white screen. Nothing is displayed on the screen!

This problem is mainly due to using a newer version of the Adafruit GFX library. The 1.5.4 release of the Adafruit_GFX library broke compatibility with the Adafruit_TFTLCD library. So you have to roll back to Adafruit_GFX 1.5.3:

Another problem you may encounter with this tft lcd shield is the poor fuctioning of the touch screen. You may find the stylus pen is not well aligned with the content you are writing on the screen.

This is due to a bug in the TouchScreen library therefore you need to locate this library by following the path to where all the libraries for your Arduino IDE are stored.

First change it to return TSPoint(1023-x, 1023-y, z). Save the changes and then compile your code again and upload to check if the touch fuction is fine.

You can keep on adjusting the values of before x and y until you get an ideal point that works best for your tft lcd. Mine worked fine with return TSPoint(x, 1105-y, z)

Due to the limited processing power of the microprocessor in the Arduino, we need to store images in bmp format and they should be 320×240 pixels sizes.

This TFT display is 2.4" diagonal and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. As a bonus, this display has a optional capacitive touch panel and resistive touch panel with controller XPT2046 attached by default.

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.

Hello, in this tutorial I planned to test different functions of the TFT LCD shield but I encountered few problems and decided to show you some solutions first, so the usual tutorial about this shield will follow up later.

This is the shield I’m using it’s 2.4″ screen, it can work with Arduino Uno, Leonardo, Duemilanove, Mega… and has a slot for SD card you can use it to store BMP pictures and display them.

So this is where the problems began for me, first you should check for the library that will work for you, to know if a library works or not, download it and open the “graphictest” example, it should show you the different colors and shapes just like in the tutorial video, if you have a white screen you may want to change the library.

If it works okay, you can now try the “tftpaint” example to try your touch functions, if it works correctly congratulations, but since you came here, you probably have the touch screen problem, and it’s due to manufacturers keep changing the pins locations.

After this re-upload the code of the paint to your board, and I hope the touch screen is now detected, if it works okay then congratulations otherwise continue the tutorial.

This is the 2.4 inch touch screen for Arduino UNO and MEGA. It use 8-bit parallel bus, faster than serial SPI refresh , support 16-bit RGB 65K color display, display rich colors , easy to expand the experiment with SD card slot.

A wide variety of arduino tft lcd options are available to you, You can also choose from original manufacturer, odm arduino tft lcd,As well as from tft, ips, and standard.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The next example is controlling an RGB LED using these three RGB sliders. For example if we start to slide the blue slider, the LED will light up in blue and increase the light as we would go to the maximum value. So the sliders can move from 0 to 255 and with their combination we can set any color to the RGB LED,  but just keep in mind that the LED cannot represent the colors that much accurate.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

As the code is a bit longer and for better understanding I will post the source code of the program in sections with description for each section. And at the end of this article I will post the complete source code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Next is the distance sensor button. First we need to set the color and then using the fillRoundRect() function we will draw the rounded rectangle. Then we will set the color back to white and using the drawRoundRect() function we will draw another rounded rectangle on top of the previous one, but this one will be without a fill so the overall appearance of the button looks like it has a frame. On top of the button we will print the text using the big font and the same background color as the fill of the button. The same procedure goes for the two other buttons.

Now we need to make the buttons functional so that when we press them they would send us to the appropriate example. In the setup section we set the character ‘0’ to the currentPage variable, which will indicate that we are at the home screen. So if that’s true, and if we press on the screen this if statement would become true and using these lines here we will get the X and Y coordinates where the screen has been pressed. If that’s the area that covers the first button we will call the drawDistanceSensor() custom function which will activate the distance sensor example. Also we will set the character ‘1’ to the variable currentPage which will indicate that we are at the first example. The drawFrame() custom function is used for highlighting the button when it’s pressed. The same procedure goes for the two other buttons.

So the drawDistanceSensor() custom function needs to be called only once when the button is pressed in order to draw all the graphics of this example in similar way as we described for the home screen. However, the getDistance() custom function needs to be called repeatedly in order to print the latest results of the distance measured by the sensor.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

Ever wanted to know how to make a simple drawing program on a LCD display, or are you curious about programming touch screens? Well, in this tutorial, we will be covering on how do you program a touchscreen display using the 2.4″ Touchscreen LCD sheild with Arduino Uno, which open up many possible applications which includes making a user friendly touch interface for making purchases, a simple touch-screen base remote control, and many more.

Hooking up the 2.4″ TFT LCD Touchscreen shield is realatively easy, since it is a Arduino shield. Just plug in the whole screen into the Arduino Uno, just note where the pins are located and connect the shield accordingly. There will be 2 parts in this tutoria, the first where you will test the functionality of the screen, and the next where you test the touch functionality of the screen.

For the graphics test of the 2.4″ screen, I used the sample sketch provided by the Adafruit TFTLCD library. The library can be downloaded here or here. (NOTE: You have to have the Adafruit GFX library installed before this library is installed, as the TFTLCD library uses the Adafruit GFX library for graphics. The library can be downloaded at https://github.com/adafruit/Adafruit-GFX-Library) A great thanks to Adafruit for their libraries.

Try uploading the example ‘graphictest’ sketch of the TFTLCD library. The screen should then be running the graphics test as shown above. If the screen displays nothing or displays only static, you may want to follow the steps taken below.

The modification I made in the example sketch is that I hard coded the LCD Driver, as for my case, the Arduino was unable to detect the LCD driver (and only produced noise on the screen).

Therefore, I set identifier variable as 0x9341 (located at line 60), which means that the shield is actually using a IL9341 LCD driver. Below are some useful links that may help if you encounter any difficulties:

This is the hardcoded sketch. Please upload the ‘graphictest’ example sketch of the TFTLCD library. If there is static or no display, you may need to modify the ‘identifier’ variable depending on which LCD driver you are using. Below is a sample code of the LCD Driver hard coded.// IMPORTANT: Adafruit_TFTLCD LIBRARY MUST BE SPECIFICALLY

Open & upload the ‘tftpaint’ example sketch from the TFTLCD library. (You may want to calibrate the screen first before using it. To do so, visit this post where I written a calibration code which can be used in this example. However, please note that certain parameters have to be changed for the calibration sketch to work with this 2.4″ screen.)

If the sketch does not run properly, you may want to do the following modifications. For my case, I need to modify a few parts, which includes:Hardcoding the LCD Driver
