2.8 tft lcd shield arduino mega supplier

This is a keyestudio 2.8 inch TFT LCD shield with touchscreen. This TFT display is driven with ILI9325 chip and has 240x320 pixels with individual RGB pixel control.

This TFT Touch Shield is Arduino/Crowduino/Arduino Mega compatible, it integrated a 2.8” TFT Display and a resistive touch panel, to make this shield suitable for handheld devices.

This TFT Touch Shield has 240x320 pixels with individual pixel control, it uses the ILI9341 driver and SPI interface to communicate with controllers such as Arduino, saving you much Arduino pins for other usages in your projects. Besides, A SD card socket is also added to help you develop applications that data storage is needed such as digital picture album.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 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 FT6206 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.

I compared the serial values that are printed between the previously mentioned NANO connected to this display with hardware SPI and default SD library compared to the exact same display and SD card connected to a MEGA and using the SDFat.h file. I am including that serial output here:

TFT Touch Shield V2.0 is a resistive touch screen, compatible with Arduino/Seeeduino/Arduino Mega/SAMD21 platforms. It can be used as display device or sketch pad. Compared with the previous version, 2.8""TFT Touch Shield V1.0, we upgraded the screen driver to a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Due to the communication method change, programs developed for the original version are needed for modification before being transplanted to the new version. With a SD card module integrated on this shield, this shield reserves capability for other expansions of your project.

Click to download the Touch Screen Driver，then please click on below button to download the library and install it, if you don"t know how to install an Arduino library, please refer to the tutorial (HOW TO INSTALL AN ARDUINO LIBRARY).

We recommend using Seeed_Arduino_LCD with internal flash chips larger than 128k. If you have a smaller flash device, I recommend using the TFT_Touch_Shield_V2.

Step1. Download and Install Seeed_Arduino_LCD. if you don"t know how to install an Arduino library, please refer to the tutorial (HOW TO INSTALL AN ARDUINO LIBRARY).

I"m sorry about the ambiguity regarding the pin names, studying the references I realize there are a number of ways to read them. Among other things I had the ATmega processor pins mixed with the pin numbers printed on the pcb, not to mention that I read the pin numbers on the two row connector from the wrong side of the pcb...

The SD card is connected directly to the two row connector at the short end of the Arduino Mega (the XIO-connector?). These pins are numbered 50-52 on the pcb which - if I have understood it correctly - translates to D50-D52?

Other ways to describe those pins are : PB0-3 which - according to "The Unofficial Arduino MEGA Pinout Diagram" (found here Tresdeland - Tu mundo 3D) - are the port pin designations.

I did use a multimeter to test which Arduino pins were connected to which resistor pack e.g. RP1 .. RP5 and the information translated to Dnn becomes :

its originally made for the arduino UNO boards, but it can be used with mega. there are two main problems while using it with the uno, the storage memory, and the pins usage! It,s hard to use the unused pins (by the screen) because all the pins are coverd with the sheild! for that resons we use better the MEGA board.

this library is one of the big libraries, it takes about 30kb of the arduino flash memory! this is too much for arduino uno! you can almost add nothing to the code with this library.

the MEGA has256kb of program memory, this is very good space and can do very good things with it, in addition, there are 54 pin most of them still free to use, and the analog just 5 are taken of 16. this is most often more that enough for most projects.

open the UTFT library file to see something similar to the first pic, then open the folder named "hardware", you should see the families of the mcu"s (AVR,ARM and pic32) the mega and uno are from the avr family, so we open it.

now you should see the arduino"s mcu that uses(ie. the uno uses the Atmega_328p ) and you can see a header file named "HW_AVR_defines" ... this is our target.. open it with some program (CODE :: BLOCKs is used here).

one quick hint, the UTFT Library is very big lib that operates depending on the board or mcu that"s used, and the module that is defined. the main utft file call the definitions of the hardware depending on your entries , so when you choose from tools-board---> arduino mega . it call the defintions of the arduino mega, to know the pins connection to the module you have sellected too.

what we gonna do here, is to edit something in the library that make the mega, uses the right defentions when you use an uno sheild with it. The utft library developer add this feature to the library, all we have to do, is to enable it.

the tft screen that we used is named on the module 2.8 ITDB02 we should find its module name in the library, open the library file and go to the documentation , you should see three files

this is our target, this file has the names of the modules and sheilds that is supported by this library, you can see in it a list of module names and module names for the UTFT which you should use to define your module.

then we name the module, which we found it called ITDB28 , then we sellect the pins, i"m not going to explain what these pins are(it"s noted in the data sheet and UTFT_Requirement.pdf file), but you should know that for this sheild, it"s located on the A5,A4,A3 and A2 pins.

when you open one of the examples that"s included in the library, you will get a note about what pins you should use, don"t forget that you use arduino uno sheild, on mega board!

for the UTFT definition, just do as the previous step, for the UTouch object definition, there ia are some change you need to make, you see the is in the note, to use arduino uno board, you should call the configuration :

this configuration is valid for arduino uno (pin 15 = A1 and pin 14 = A0) and further more for another module, this module has the pin 9 and 8 reversed!

actually, this code is used for calibrate the screen, after following the instruction on the screen, you will get the result of the test, it"s the x,y calibration, you can ooen the utft library source code , find those parameters and edit them! however it"s not essential thing to do, but it suppose to give you more accuracy whit your touch coordinations!

Hello I"m Brian from Limburg the Netherlands. I"ve orded a Velleman VMA412 2,8 inch TFT touchscreen display. If I downloaded a scetch my display remains white. While a paint scetch was uploaded once saying my TFT screen appears to be a ILI9341 type and when programming with that kind of display my program dos"nt match. My question is there any driver for this kind of display? My kindly regards.0

Hallo from germany.I have a little problem , my tft stays white . I have uncommented the Mega board definition. But I don´t know wihtch modul name i must write in the

Hello Antonio, did You solve your problem yet? For me it was ITDB28 (for the Mega and should use A5,A4,A3,A2). But I still have the same blanc display.

i can suggest something! maybe you can use the arduino mega to drive the tft, and connect it to the raspberry bi by serial or something, this way you can uss the function of the pi and the the easy drive of the mega!

I am trying to make a truly Universal Remote Control out of this mess. I just got the Arduino Uno & the Display and put it together and there are NO pins left to operate an IR LED.

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

Is there any way, with an UNO, to add other I/O, given all the pins are used/covered, and none are brought through? I"d like to interface a 5-pin joystick. Is the only answer "buy a Mega"?ReplyUpvote

I"m thinking I need an Arduino Mega to do what I want - a Universal Remote. Because after mounting the display there are NO pins left for anything else.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

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 controllerILI9325, 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 isXPT2046, 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.(Click here)

Add some sizzle to your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection and a capacitive touchscreen. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a capacitive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This shield is the capacitive version as opposed to the resistive touchscreen we also sell. This touchscreen doesn"t require pressing down on the screen with a stylus, and has a nice glossy glass cover. It is a single-touch display.

This shield uses SPI for the display and SD card and is easier to use with UNO, Mega & Leonardo Arduino"s. The capacitive touchscreen controller uses I2C but you can share the I2C bus with other I2C devices.

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/Duemilanove/Diecimila). Solder three jumpers and you can use it at full speed on a Leonardo or Mega as well.

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This shield needs fewer pins than our v1 shield, so you can connect more sensors, buttons and LEDs: 5 SPI pins for the display, 2 shared I2C pins for the touchscreen controller and another pin for uSD card if you want to read images off of it.
