arduino tft lcd mega shield sd card example pricelist

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (3.5" diagonal) bright (6 white-LED backlight) and colorful (18-bit 262,000 different shades)! 320x480 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 FT6236 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 pin32 (SDO) of 3.5 display module is also used by touch panel or SD card SPI interface, so we must cut off this pin to avoid conflict with the touch panel or SD card.

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 (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 puzzled some hours with exactly the same hardware setup and made a quick & dirty, but successfully test script, combining LCD, Touch and SD Card Features.

This line of code creates a file called data.txt on your SD card. If the data.txt file already exists,  Arduino will open the file instead of creating another one.

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

The Shield TFT is usually supplied with an SD card module to store data or images. Touchscreen LCDs to display images and create graphical user interfaces. In this tutorial, we use the Kuman TFT 2.8″ shield (very similar to the 3.5″ shield) and we will see how to interface with the microSD card.

The shield is placed directly on an Arduino UNO or Mega board. The shield uses almost all the pins of the Arduino UNO. Make sure you don’t use the same ones for other modules. The SD card module of the TFT shield uses the SPI bus and selector pin 10.

The main interest of the MicroSD module on the TFT shield is to be able to store images in order to display them on the screen. If you don’t have a bitmap image at hand, you can download the one we use in this example.

We will create a button for each file and with the help of the previous function we will display the images contained in the SD card when we press the corresponding button.

Once the code is uploaded, a menu will appear with a button for each file contained on the SD card. If you press a button, the corresponding bitmap image will be displayed on the screen. If you press the screen again you will return to the main menu.

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 you elaborate on which libraries will work, I"ve been fighting with this thing since I got it. I need it to play a simple video if possible. I"m trying to help an elderly lady in her 80s be able to watch videos from the SD card. Any help would be greatly appreciated. It"s for a very good cause.0

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
