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
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

I had some success with this. By observing the sketches I decided that at least in the BMP sketch that A5 did not seem to be used. I have another Shield called the Dr Dunio that can redirect most of the GPIO pins to another option by use of a jumper. I placed the Dr D shield in my UNO and then placed the LCD shield on top of it. The Dr D board has 16 jumpers that can be in one of two positions. With the jumper in a position marked with a dot the pin effectively goes straight through to the header where the LCD shield is installed. So with all jumpers in the dot positions, the Dr D shield passes all pins straight through. I determined that the jumper on pin A5 could be placed in the dot position, the non dot position and even removed and the LCD sketch worked properly. I then put the Dr D jumper on the non dot position which connects it to a pot on the Dr D shield. I added in a few lines of code which did an analogRead (A5) and printed it out on the Serial Monitor. I could change the pot of the Dr D board and see a corresponding change in the Serial Monitor. All the while the pictures on the LCD screen were acting as before. This leads me to believe I can use A5 for my own purposes. Unfortunately my choices are somewhat limited with only this pin available.
Today, you will learn how you can create and use buttons in your Arduino TFT Touchscreen projects.I"m using Kuman"s 2.8" TFT Shield combined with Kuman"s Arduino UNO. Bonus: The TFT Shield from Kuman comes with a free Stylus which you can use for more precise presses!
I tried it with your sketch, but it did not work firstly. However I fixed some part of the sketch, it worked. "tft.begin(0x9325);" to " tft.begin(0x9341);"0
Normally we show example of real-time reading things like DHT11 on monochrome LCD displays. We can graph that information. Graphing With Arduino on TFT LCD Color Display Probably a Needed Matter to Many Users. Graphing Can Become Difficult On Display With Less Known Drivers. Previously we have talked around MCUFRIEND TFT LCD Calculator. That one had problem with working codes. There are worse displays which are sold. Worse in the sense – most of the Arduino users need some easy working library which works with most common matters. This guide discuss some of the basic matters for the displays which use Elegoo Libraries (Adafruit Industries) and MCUFRIEND TFT LCD. The logic will be same for all similar displays but some tweaks needed for the others to make graph in proper orientation.
Basically I purchased one Elegoo 2.8′ TFT LCD and was searching for graphing for some other reason. You can directly open this link to use in Arduino Web Editor. To use the same code on other boards, you need to modify some parts like :
In next article, we will see how we can graph values read by LDR on MCUFRIEND display. That is hopefully will be simple. Although with my model of MCUFRIEND TFT LCD, it not going to be easy to make it properly oriented.
Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (5" diagonal) bright (12 white-LED backlight) and colorfu 480x272 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel attached on screen 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).
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!
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.
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.
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.
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.
