2.8 tft lcd shield v3 free sample

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.

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!

Clip in the shield onto your Arduino board. Make sure it"s not in the wrong way!You can use the pictures above for reference. Plug in your Arduino board to your PC and hop into the Arduino Software.

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

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.

I created my own “TFT Touch Shield” example sketch for my Arduino Duemilanove and in need of connecting it via I2C bus to my Arduino Nano 3.0 (ATMEGA328). After plugging into my serial shield which is in turn plugged into my Duemilanove, I had only Digital 0 and 1 , and Analog 4 and 5 left available for use.

If it helps here is my TFT Touch Shield Example Sketch - the sketch was made with the Seeedstudio examples provided on your Wiki for the 2.8" Touch Shield. Please feel free to chop it up as it’s my first attempt at programming. I really need the feedback. (pls post ONLY constructive though)

this is the latest version of the first and original TFT touch panel display board designed specifically for the Raspberry Pi. This hardware version is compatible for all 40-way GPIO Pi"s, so that is the A+, the B+ and the latest Pi 2B and uses the established HY28B display board which features a resolution of 320 x 240 at 65k colours. As usual the display utilises the excellent fbtft drivers authored by notro, only now those drivers are included in the very latest raspbian image, although not currently included in the image available from the foundations download page. I expect this to change in the very near future so that the rpi-update step is no longer required.

It is recommended to use the latest raspbian image , at the time of posting is dated 2015-02-16, to configure using an SSH session remotely, with no TV/Monitor connected to the HDMI port, and to connect the 2.8" Display board right from the start prior to connecting power to the Pi.

Note all of the instructions in this post assume you wish to use the display/touch panel in landscape mode, with the hdmi connector at the top as you look at the pi/shield.

HY-TFT280 is a 2.8 inch TFT LCD Screen module, 320*240 (resolution), 65K color, 40pins interface , not just a LCD breakout, but include the Touch screen, SD card. So it’s a powerful extension module for your project.

This Screen includes a controller ILI9331, it’s 16bit data interface, easy to drive by many MCU like STM32 ,AVR and 8051.HY-TFT280 is designed with a touch controller in it . The touch IC is XPT2046 , and touch interface is included in the 40 pins breakout. Another useful extension in this module is the SD Card socket . It use the SPI mode to operate the SD card, the SPI interface include in the 40pins breakout.

The TFT library is required to be installed to get this screen model display. This library is especially designed for TFT LCD screen using 16 bit mode. The library require the following connections.

Note: The TFT controller model needs to be declared in the initializing statement. ITDB02 myGLCD(38,39,40,41) needs to be modified as myGLCD(GEEE28,38,39,40,41) when using Arduino Mega2560.ITDB02 myGLCD(GEEE28,19,18,17,16) needs to be commented when using Aduino UNO. Otherwise it just show a blank screen. In practice, RS, WR, CS, RSET can be connected to any free pin. But the pin number must be in accord with myGLCD(RS,WR,CS,RST).

The LCD has a 2.8" 4-wire resistive touch screen lying over it. The Touch library needs to be installed to get it works. This library is designed for 2.4’’ TFT, 2.8” TFT LCD screen module.

The default setting is accurate for 2.4” TFT module, but you need to calibrate when using 2.8” TFT module. A program to calibrate the touch screen is included in the example. If you touch screen is inaccurate, you need to run touch_calibration. Follow the on-screen instruction to calibrate the touch screen. Better not use your finger to calibrate it, use your accessory touch pen to pressure the frontsight with stength. Then record the calibration parameters and apply them in ITDB02_Touch.cpp in your touch screen library.

There is built-in SD card slot in the shield, so we can use it to upload images. But the images need to be converted RAW format first. SD libraries tinyFAT and tinyFAT_16 need to be preinstalled for displaying the image.

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! This Fantastic 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 comes with a resistive or capacitive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

The TFT LCD library is based off of the Adafruit GFX graphics core library. GFX has many ready to go functions that should help you start out with your project. Its not exhaustive and we"ll try to update it if we find a really useful function. Right now it supports pixels, lines, rectangles, circles, round-rects, triangles and printing text as well as rotation.

We have example code ready to go for use with these TFTs. Libraries need to be downloaded and installed. Such as:dmtftlibrary,Adafruit ILI9341 library, andAdafruit GFX Library!
