tft lcd screen shield for arduino due quotation

※Controller IC Replacement NoticeDue to the global shortage of IC, the controller RA8876 used in this module has been difficult to purchase. In order not to affect the delivery, we will use the controller LT7683 as replacement which is fully compatible with the same stable performance when the RA8876 is out of stock. (Oct-28-2021)

Spice up your Arduino project with a beautiful large display shield with built in microSD card connection. This TFT display is big (10.1" diagonal) bright (24 white-LED backlight) and colorful (18-bit 262,000 different shades)! 1024x600 pixels with individual pixel control,optional 10.1 inch capacitive touch panel.

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 Arduino Due board.

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. 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.

I am building a HAM Transceiver-Shield for 23/13/9/6 cm wavelenghs for the Arduino Due. On the shield there ist a MAX2871 PLL_SYnthesizer-Chip, which i want to control over the second SPI, then there also is mixer i have to turn on/off, two SHF-switches to select the right bands and bandpass-filters, and a reflectometer with two A/D - conversters to meassure forwarded and reflected SHF-power. Furtermore i need a rotary-encoder with push-button and the touch-display to show and modify parameters in the menu.

So i am already using up quite a lot of analog and digital pins of the due. Thats also why i want to connect the touch-shield with dupond-cables and make it work, my shield will sit on top of the arduino, the display will be mounted to a metal-case...

I have looked into the GitHub - ImpulseAdventure/Waveshare_ILI9486: Arduino library for Waveshare ILI9486 supporting the Waveshare 3.5" & 4" TFT Touch Shields for Arduino. Includes GFX-compatible API and touchscreen driver resources and was able to compile the examples for the 4"" display and also the ws_graphictest, but only on create.arduino.cc.

boolean DebuggingMode=1;// If set to 1, Debugging Information to Serial Monitor will be available (115600 Baud), but System will slow down a little bit!

In the next step i will investigate, which pins on the due i have to use, at the moment i am using more than i would like to, because i will need every pin available for my transceiver-shield...

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:

This module is designed to plug directly into Arduino UNO R3 (or its clone) boards. It is compatible with CH340 and Atmega16u2 version boards, as well as Mega 2560. This LCD shield may also work with other boards, but the compatibility can"t be guaranteed.

I know that the TFT is not faulty, because I used it on an Arduino Uno using a different library, and it worked just fine. The problem with this library is that it only works on AVR processors, and as you know, the due uses an ARM processor. Does anyone know how to get something to show on screen? I would be ok with losing the sd card reader and maybe touch, but those would be a plus to keep! Thanks for reading!

I wired it up according to UTFT"s documentation, adapting it to the specific TFT. It was not difficult. I should point out that it is an ITDB32WD compatible display that I got off of ebay, and not an ITead original.

The display works natively with 3.3V logic (I had to use resistors to use it with the older Arduinos) so it is actually easier to interface to the Due than to older Arduinos.

I try to convert the UFT Clock from Henning Karlsen to work with the Due Electronics - Henning Karlsen. But my Calender is blinking the clock is working proper.

I don"t use the UTFT library, but I have a sainsmart TFT shield with a mega using an SSD1289. I"m interested to see how it compares to the Due implementation.

then what Library are you using? I also have a Mega and a TFT display, but it takes about a second to clear the screen! I would love to have it run faster!

also, I hope this gets noticed by the creator of the UTFT library, who wants to port it to the Due but can"t because he doesn"t yet own one. I guess this would make porting a whole lot easier.

Here"s one more thing, when using samples (or doing your own) - you need to change bitmap definitions a bit to make it work.. For example, tux.c in UTFT_Rotate_Bitmap example:

Yes, but you need to get itdb02_32s display and mega shield for it from iteadstudio.com, these sources are compatible with that display and propably only with that display, other than 16bit modes are removed and this library only supports arduino due as I replaced and removed code, instead of just making it compatible with due along others. But here"s a library, examples work "as is" with mega pins chosen on utft init..

then what Library are you using? I also have a Mega and a TFT display, but it takes about a second to clear the screen! I would love to have it run faster!

I"m having a go at building my own driver, the mainstream libraries are too slow for games and interactivity. They all suffer a similar overhead with respect to being portable between uC"s and compatible with multiple devices. Whereas I"ve targeted my code directly to the 2560 and the display. I"ll post the code on the forums eventually.

I"ll probably post the code in the display forum. If you would like to see its current performance, I have posted a video here: http://arduino.cc/forum/index.php/topic,140111.0.html

I"ll also post any info on the library there. Remember my info was for a Mega 2560, not the Due. Although I guess its a good reference to see what we can expect at a minimum from the Due.

Just wondering as I"m working on a DSP/DAC project and arduino due is the controller of choice running the Hifiduino code for now until I learn how to code.

I have been poking around with it and sort of have the one from seedstudio working, The library would like to just write the data to the register but the due registers are all in different places in due so i made it digital read and digital write. Lots of overhead and poor performance. Was quite shocked it sort of worked at all. The touch screen was not at all hard to make work, but the tft is a nightmare.

Thank you for your post about the Karlsen library. I have installed the library and the examples compile without error. However, I get nothing on my SainsSmart 3.2" 320x240 display which uses the SSD1289 driver. I looked at the code samples and they are for the "uno" and "mega" boards (comment in/out appropriate myGLCD statements). I presume the numbers assigned by myGLCD are pin specific for each processor. I do not see any examples with the pins for the DUE board (SAM3E processor). I tried the "mega" example" and I get nothing on my screen. Does anyone know what the pin numbers for the DUE are? If not, do anyone know what these pins are for (e.g., name, function) so I can look them up in the SAM3E datasheet? Any other suggestions for getting started would be appreciated. Thank you!

For the incial subject, YOU CAN USE A MEGA TFT shield (al least, this one http://qqtrading.com.my/32-inch-lcd-tft-screen-for-arduino-mega-2560-shield-compatible) with the Arduino DUE, even use the UTFT and the SdRaw librarys.

Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today’s tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino.

This 3.5″ color TFT display as mentioned above, is based on the ILI9481 TFT display driver. The module offers a resolution of 480×320 pixels and comes with an SD card slot through which an SD card loaded with graphics and UI can be attached to the display. The module is also pre-soldered with pins for easy mount (like a shield) on either of the Arduino Mega and Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.

The module is compatible with either of the Arduino Uno or the Arduino Mega, so feel free to choose between them or test with both. As usual, these components can be bought via the links attached to them.

One of the good things about this module is the ease with which it can be connected to either of the Arduino Mega or Uno. For this tutorial, we will use the Arduino Uno, since the module comes as a shield with pins soldered to match the Uno’s pinout. All we need to do is snap it onto the top of the Arduino Uno as shown in the image below, thus no wiring required.

This ease of using the module mentioned above is, however, one of the few downsides of the display. If we do not use the attached SD card slot, we will be left with 6 digital and one analog pin as the module use the majority of the Arduino pins. When we use the SD card part of the display, we will be left with just 2 digital and one analog pin which at times limits the kind of project in which we can use this display. This is one of the reasons while the compatibility of this display with the Arduino Mega is such a good news, as the “Mega” offers more digital and analog pins to work with, so when you need extra pins, and size is not an issue, use the Mega.

To easily write code to use this display, we will use the GFX and TFT LCD libraries from “Adafruit” which can be downloaded here. With the library installed we can easily navigate through the examples that come with it and upload them to our setup to see the display in action. By studying these examples, one could easily learn how to use this display. However, I have compiled some of the most important functions for the display of text and graphics into an Arduino sketch for the sake of this tutorial. The complete sketch is attached in a zip file under the download section of this tutorial.

As usual, we will do a quick run through of the code and we start by including the libraries which we will use for the project, in this case, the Adafruit GFX and TFT LCD libraries.

With this done, the Void Setup() function is next. We start the function by issuing atft.reset() command to reset the LCD to default configurations. Next, we specify the type of the LCD we are using via the LCD.begin function and set the rotation of the TFT as desired. We proceed to fill the screen with different colors and display different kind of text using diverse color (via the tft.SetTextColor() function) and font size (via the tft.setTextSize() function).

The Adafruit library helps reduce the amount of work one needs to do while developing the code for this display, leaving the quality of the user interface to the limitations of the creativity and imagination of the person writing the code.

That’s it for this tutorial guys, thanks for reading. If you made some cool projects based on this or you just want to ask questions about this tutorial, feel free to reach out via the comment section below.

2.4″ Inch Touch Screen TFT Display Shield adds a touch up to your Arduino project with a beautiful large touchscreen display shield with built-in microSD card connection. This TFT display is big (2.4″ diagonal) bright and colorful! 240×320 pixels with individual pixel control. It has way more resolution than a black and white 128×64 display.

Let"s get started with this creative Arduino project, where you"ll learn about the TFT LCD touch screen and how to use it to create your own colourful calculator. For a basic understanding of touch screen & LCD, a cheap TFT 2.4" Arduino shield is used to create this project. For creating a similar project, one should follow the steps and edit the code for better understanding.

Touch-screen devices using resistive technology, a two-dimensional membrane potentiometer provides x and y coordinates. The top layer is thin glass spaced close to a neighboring inner layer. The underside of the top layer has a transparent conductive coating; the surface of the layer beneath it has a transparent resistive coating. A finger or stylus deforms the glass to contact the underlying layer. Edges of the resistive layer have conductive contacts. Locating the contact point is done by applying a voltage to opposite edges, leaving the other two edges temporarily unconnected. The voltage of the top layer provides one coordinate. Disconnecting those two edges, and applying a voltage to the other two, formerly unconnected, provides the other coordinate. Alternating rapidly between pairs of edges provides frequent position updates. An analog to digital converter provides output data.

The shield connects ILI9341"s data pins 0-7 to Arduino"s digital pins 2-8 (allowing parallel communication, not SPI. ILI9341"s RESET goes to Arduino analog pin A4. CS (chip select) to A3. RS (CD command/data) to A2. WR and RD to A1 and A0.

ILI9341 is integrated inside the display. It drives the display and has nothing to do with the touchscreen (Although the shield connects some pins of ILI9341 together with pins of the touchscreen).

Now, open Arduino IDE and select Sketch -> Include Library -> Add .ZIP library. A browser window will open navigate to the ZIP file and click “OK”. You should notice “Library added to your Libraries” on the bottom-left corner of Arduino, if successful.

The touchscreen I tested sometimes wrongly detects a touch, outside of the touched point. To prevent this I added some delays and the X and Y analog value is read repeatedly and touch is approved only if values do not differ a lot.

You can also find an SD card slot at the bottom of the module shown above, which can be used to load an SD card with BMP image files, and these images can be displayed on our TFT LCD screen using the Arduino Program.

The 2.4” TFT LCD screen is a perfect Arduino Shield. You can directly push the LCD screen on top of the Arduino Uno and it will perfectly match with the pins and slid in through. However, as matters of safety cover the programming terminal of your Arduino UNO with some insulator, just in case if the terminal comes in contact with your TFT LCD screen.

The calculator here is based on the simple logic that, you have to divide the screen according to touch coordinates values and write a program accordingly. Every digit or symbol visible on-screen have a defined area.

This 4inch Touch LCD Shield for Arduino is resistive touch screen TFT LCD, 4inch with a 480x320 resolution. The screen has a standard Arduino interface and is compatible with development boards such as: Arduino UNO, Leonardo, UNO PLUS, NUCLEO, XNUCLEO, ect.

The 4" screen has an onboard stand-alone touch controller, better touching than solutions that use AD pins directly for touch control. The PWM backlight control allows you to adjust the backlight to a comfortable level, and the micro SD slot provides an easy way to store photos for displaying. Controlled via SPI, only a few Arduino pins are used and comes with STM32 and Arduino examples allowing for more convenient porting.
