2.8 tft lcd shield arduino mega in stock

This is a multifunctional Arduino/Seeeduino/Arduino Mega compatible resistive touch screen. It can be used as display device or sketch pad.Compared with the previous version,

Edit: Removed SdFatSoftSpi from the showBMP_not_Uno.ino example, no need for Software SPI due the fact that this shield uses the hardwired SPI pins from the Mega2560 (MISO = 50, MOSI = 51, SCK = 52) and does not share them.

It has the XPT2046 touchsceen controller chip on it (top-right) but has voltage regulator AMS1117 (down-left) missing, this seemed not to be a problem to get the shield fully working.

When using the arkejan/UTFT library (other UTFT libraries must be (temporarly) removed from the Arduino IDE libraries folder), you invoke the screen with:

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)

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. It 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. (We also have a capacitive-touch version of this shield here)

We"ve updated our original v1 shield to an SPI display - its a tiny bit slower but uses a lot less pins and is now much easier to use with Mega & Leonardo. We also include an SPI touchscreen controller so you only need one additional pin to add a high quality touchscreen controller. Even with all the extras, the price is lower thanks to our parts sourcing & engineering skillz!

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, another pin for the SPI touchscreen controller and another pin for uSD card if you want to read images off of it.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library 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!

Arduino 2.8" TFT LCD Touch shield is an Arduino UNO/ Mega compatible multicolored TFT display with touch-screen and SD card socket. It is available in an Arduino shield compatible pinout for attachment. The TFT driver is based on ILI9325DS with 8bit data and 4bit control interface.

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.

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.

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!
