Can this 2.8" elegoo display play video at all? I"m trying to make a unit that an older woman, in her 80"s can play a video on it, if I set it up correctly? This is for a really good cause, I desperately need help, this is super important. Helping elderly folks with modern technology is tough. But I really need it to be able to play a video off the SD card if possible. Any help would be super highly appreciated.ReplyUpvote

Hello,please post our code also ..the screen driver must be known and that info must be known in order to get these things to work correctly..you show your code and then the vid blurs..Someone needs to write a pdf teaching how ,what ,when and why concerning these screens I would gladly pay $10.00 and I am sure others would too.I have 3 different tftlcds only 1 works its for the mega and Bomer has a lib for it,I am really considering use of Nextion units from now on 4 pins easy programming but higher cost...also the small cell phone screens use spi mode and are real easy to set up and use

The program runs and nothing is displayed but a white screen. when I open the COM4 I see that when I hit the screen numbers appear to calibrate the screens position so it is registering but not showing up on the LCD. please help me before I pull all my hair out.1

Thank you for the instructable. I"v been trying to build a DIY smartphone but couldn"t get the code or libraries for the touch screen. Now i can finally build it. Thanks.0

I"m having issues getting this display to work on my Arduino 101 board with the libraries that are suggested - errors in compiling seem to indicate that the board type isn"t supported in the Adafruit_TFTLCD library. Here"s a representative error:

I finally got the touchscreen to work correct using your links to the libraries. Found out that this specific TFT display module uses pin 6 & 7 for touch sensor, instead of the standard 4 & 5.0

I never received a response on this, so went through the painful process of copying code from the video. It can be found here for others that might need it. Not that this has some minor changes, but is fully functional and I will continue to refine: https://github.com/siliconghost/Arduino_2.8in_TFT_wSD

Hello everyone to my new tutorial in which we are going to program arduino for tft lcd shield of 3.5" with ILI9486 driver, 8 bit. I found it important to write this tutorial as if we see we find tutorial for 1.44, 1.8, 2.0, 2.4, 2.8 inch shields however there are no or less tutorials available for 3.5" shield as its completely different from other smaller tft lcd shields -adafruit tft lcd library doesn"t even support ILI9486 driver in 3.5" tft lcd, it supports drivers of tft shields lesser then 3.5"

Go through the above link to know better, lets start with our tutorial however if we can"t use Adafruit_TFTLCD library which library will we use ?, there"s a simple answer to this that"s MCUFRIEND_kbv library which helps to use 3.5" tft lcd shield, if you see this library makes it much more easier to program arduino for tft lcd shield than adafruit as we have to simply create a tft object in MCUFRIEND_kbv library and then using that we can control the tft lcd shield however in Adafruit_TFTLCD library we will have to create the object and also define connections which makes it a very long task.

Once added, create the tft object using library name and a name for object, you can also define some color codes for text which we are going to type, using the define function and giving color code. This all is to be done before setup.#include#include#define BLACK 0x0000#define RED 0xF800#define WHITE 0xFFFFMCUFRIEND_kbv tft;

Its time to now start our tft lcd screen and change the background, this is to be done by using some simple functions by obtaining the tft ID and changing the background bytft.fillScreen("color_name");void}

Now we will be programming in loop for printing text on TFT LCD shield, for that we will be using a number of functions such as -tft.setCursor("x","y");x means the position from the x axis on screen and y means position from the y axis on screen of tft lcd shield.tft.setTextSize("number");number here refers to text size which take parameter as number you can give any number from 1 according to your requirements.tft.setTextColor("color");color here means to give the color name we had defined before setup, this makes the text color as whatever you give.tft.print("value");value is nothing but what you want to print, whatever you give as value must be in double quotes.void loop() {// put your main code here, to run repeatedly:tft.setCursor(0,0);tft.setTextSize(3);tft.setTextColor(WHITE);tft.print("my first project with tft -");tft.setCursor(0,70);tft.setTextSize(2);tft.setTextColor(RED);tft.print("welcome to the world of arduino and display , myself I love arduino and game programming very much. This is why I have my own youtube channel in which I share my arduino projects and games made by me , isn"t it amazing !");}

Graphics which we see in our phone is combination of square, rectangle, circle, triangle, lines. This is why here we will learning how to draw the following shapes.tft.drawRect(x,y,width,height,color);x means the position from the x axis of the screen, y means the position from y axis of the screen, width refers to set the width of rectangle, height refers to set the height of the rectangle and color means the color of rectangle you want it to be. You can use this same function by simply keeping the height and width same.tft.drawCircle(x,y,radius,color);x means the position from the x axis of the screen, y means the position from y axis of the screen, radius is a para to set the radius of circle and color means the color of circle you want it to be.tft.drawTriangle(x1,y1,x2,y2,x3,y3,color);x1, y1, x2 etc. are to set the position of triangle"s three points from which lines are drawn.tft.drawLine(x1,y1,x2,y2,color);x1 and y1 are to set point 1 from which line is made to point 2 which is set by x2 and y2.

I have shown we can draw text and shapes by which we can make various graphics, you can also refer to code given by me, one is for text and other is for graphics display.

SainSmart 2.8" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and mutilfunctional module for your project.The Screen include a controller ILI9325, it"s a support 8/16bit data interface , easy to drive by many MCU like arduino families，STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is XPT2046 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.

Voltage type: 5v or 3v voltage input voltage，input is selectable. Because TFT can only work under 3.3 V voltage, so when the input voltage VIN is 5V, need through the 3.3 V voltage regulator IC step down to 3.3V , when the input voltage of 3.3 V, you need to use the zero resistance make J2 short , is equivalent to not through the voltage regulator IC for module and power supply directly.

The new line of 3.5” TFT displays with IPS technology is now available! Three touchscreen options are available: capacitive, resistive, or without a touchscreen.

Hi. I also got this display (off ebay). I found a contact email on the mcufriend.com website, so i emailed them, and after a few exchanges i was sent a sketch called _8347uno that makes the screen go black instead of white. i count this as some progress, however im not very knowledgeable on how the code works. perhaps somebody can use it as a basis to make a library to make these work?

i looked up 8347 and found there is are controllers with that number, and i tried the UTFT set up for the HX8347A controller with no luck, but im hoping someone with more knowledge than me can figure it out.

Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful! 240x320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This TFT kit comprises one of our smallest TFT displays and an adapter board that breaks the tail connections out to a simple 2x5 10-position header. The adapter board includes a backlight driver, so only a single 3.3v power input is required to bring up the display.

You can also just use the shield as an LCD display and ignore the two other components, however, if you intend on doing that it would be cheaper just to buy an LCD display without any touchscreen features.

This is a TFT orThin Film Transistordevice that uses liquid crystals to produce a display.  These displays can produce a large number of colors with a pretty decent resolution.

You do need to be looking directly at the display for best color accuracy, as most of these inexpensive LCD displays suffer from distortion and “parallax error” when viewed from the side. But as the most common application for a device like this is as a User Interface (UI) this shouldn’t be a problem.

For the LCD you will have a lot of choices in libraries. Most of these shields come with a CD ROM with some sketches and libraries, so you can use the LCD libraries there. Bear in mind however that code on these CD ROMs tends to be a little dated, you may have better lick on the vendors website.

This useful resource contains code, libraries and datasheets for a wealth of LCD displays, both touchscreen and non-touchscreen. You’ll also find code for some common OLED displays as well.

I ran my touchscreen through all of the code samples I obtained from the LCD Wiki. It’s an interesting exercise, and by examining the sketch for each demo you can learn a lot about programming the display.

This test does not make use of any of the extra libraries, it drives the LCD directly. It is only a test of the LCD display, it does not make use of the touchscreen membrane.

This example does use the custom libraries, and is a very good way to learn how to use them.  You’ll note that theLCDWIKI_GUI.hlibrary is loaded, which is the graphics library for the LCD display.

Another library, LCDWIKI_KBV.h, is loaded as well. This is a hardware-specific “helper” library that provides an interface to the actual hardware for the other libraries.

A look at the loop will show how this is done. TheLCDWIKI_GUI.hlibrary has a “Fill_Screen” method that fills the screen with an RGB color. You can specify the color in both hexadecimal or decimal format, the example illustrates both ways.

The example itself is in a folder labeled “Example_03_colligate_test” and the code itself is in the colligate_test.ino file. I suspect a translation error resulted in the name!

This sketch uses a number of functions from theLCDWIKI_GUI.hlibrary, along with some custom functions to draw geometric shapes. It then displays a cycle of graphs, shapes, and patterns on the LCD display.

The image needs to be in bitmap format as this format defines several bytes for each individual pixel in the image. There are four 320×480 sample images included in the code sample, you can also use your own if you (a) keep them the same size and (b) give them the same names.

While the sample code is a bit difficult to follow it’s worth the effort, as it shows you how to create a dynamic menu system. Touching the stylus color button, for example, will open a new menu to select colors.  This is a handy technique that you’ll need to know when developing your own user interfaces.

The examples are a great way to demonstrate the capabilities of your touchscreen. But to really put your interface to work you’ll need to write your own interface code.

Writing a touchscreen interface can be challenging. I would suggest that you start by modifying one of the example codes, one that is closest to your desired interface.

The sketch is based upon the telephone keypad sketch. I modified it to eliminate the other functions and just display three buttons.  Then I added code to toggle the LEDs.

TheAdafruit TFTLCD Libraryis used. It uses the previous library to provide an easy method of drawing on the LCD display.  It works with LCD displays that use driver chips like the ILI9325 and ILI9328.

TheTouchScreenlibrary comes in the code that you downloaded from the LCD Wiki or from the CD ROM included with your touchscreen shield.  As its name implies it is used to interface with the touchscreen.

We also define some “human-readable” colors to use within our code, it’s a lot simpler and more intuitive than providing RGB values.  I’ve includes all of the colors from the phone sketch I used as the basis for this code, so if you want to change button or background color you can easily do it.

Next, we define some touchscreen parameters. You can ‘fine-tune” your code here by using parameters from your own display, which you can obtain from the Calibration Sketch we ran from the sample code.  Otherwise, just use the values here and you should be fine.

Now, still in the Setup, we set up the LCD display rotation and fill the background in black. Next step is to draw our buttons. Once we are done that the Setup is finished, and our screen should be displaying the three buttons on a black background.

We then need to reset the pin modes for two of the touchscreen pins back to outputs. This is done as these pins get shared with other LCD display functions and get set as inputs temporarily.

Load the code into your Arduino IDE and upload it to your Arduino Mega 2560. Make sure you have the correct processor-type set in your Arduino IDE, especially if you are used to working with the Uno!
