Looking for a bigger screen to interface with the Arduino Uno? Bigger than the 2.4″ TFT LCD screen, this shield is able to display a little more information than the 2.4″ screen. In this tutorial, we’ll be looking at how we would interface the 2.8″ TFT LCD Touchscreen Shield with an Arduino Uno.

As this is an Arduino Shield, just attach the shield to the Arduino Board. (Uno, Mega, etc.) But in this tutorial, we’ll be connecting the shield to an Arduino Uno.

We’ll be using Adafruit’s GFX and TFTLCD library to interface the LCD shield with Arduino Uno. Download the library, extract the rspective folders and place it in your Arduino libraries directory.

Before using the TFT LCD Shield, we should first calibrate the touch screen. As there weren’t any calibration sketch provided in the librarie’s example, I wrote a simple calibration sketch to calibrate the touch screen. With this sketch, adapted from Adafruit’s tftpaint example sketch, it will display the offset that will remap the values of the raw values of the TFT resistors to the coordinates of the screen.

The values displayed at the end of the calibration will be used to determine the TS_MINX,TS_MINY, TS_MAXX & TS_MAXY variables. These variables are actually the resistance value of the TFT screen, which will be “converted” into coordinates relative to the screen:p.x = map(p.x, TS_MINX, TS_MAXX, 0, tft.width());

Upload the following code below to obtain the offset values. Remember to note down the respective values (TS_MINX,TS_MINY, TS_MAXX & TS_MAXY), as it is needed for the next section of the tutorial.// Paint example specifically for the TFTLCD breakout board.

After the calibration is done and the (maximum & minimum) X/Y resistance values recorded, we’ll proceed on to running the tftpaint demo. Open up tftpaint sketch from Adafruit’s TFTLCD examples.

When you draw something on the touch screen with the original sketch, the X coordinates will be inverted. To fix it, we’ll have to flip the mapping function from :// scale from 0->1023 to tft.width

Open up your serial monitor & see whther the library is able to detect the driver. If the Serial Monitor returns something like this:Unknown LCD driver chip: 0x00

You can try hard-coding the driver of the LCD Shield specific to the shield you have. You can figure it through these following methods:Turn to the back of the shield & look for the chip ID

After you have figured out the driver ID, we’ll hard code the driver ID. Modify this line of code (at line 92) from this:uint16_t identifier = tft.readID();

Add some pizazz to your arduino project with a beautiful large touchscreen display shield with built in MicroSD card slot and a capacitive touchscreen. This TFT display is big (2.8" diagonal) bright (4 white-led backlight) and colorful (262, 000 different colors!) 240x320 pixels with individual pixel control. It has a lot 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 IEC 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 controller. 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. Of course, we wouldn"t just leave you with a data sheet and a" good luck!" - we"ve written a full open source graphics library that can draw pixels, lines, rectangles, Circles and text.

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.

This is SainSmart TFT LCD Extend shield for UNO(R3) .Using this shield can help you out of the bothers to use other cables. You just need to plug the module to arduino UNO(R3) through this shield.

If you connect the touch screen LCD with UNO R3, the touch screen function will be useless . If you want to use the touch function, please connect the LCD with Mega2560 (R3) or Due (R3).

2.The LCD is compatible for arduino family,but the Shield is just for the arduino UNO R3. If you need the LCD Extend shield for other arduinos, you need another shield which is also provided from our store.

This is a versatile and Arduino/Seeeduino/Arduino Mega compatible resistive touch screen shield which can be used as display device, or sketch pad for user input/interface.

Compared with the previous version (2.8" TFT Touch Shield V1.0) we improved the screen driver with a professional chip (ILI9341) to provide the pin-saving SPI communication protocol without sacrificing the data transmission speed.

Circles isn"t the only thing our library can help you draw, we also have a lines, number, rectangle, and many more examples. Check those out as well to become a pro with the shield.

Function Description: The drawCircle function draws an empty circle with the center at the coordinates poX, and poY. The circle will be of radius r and the border color will be color. The color parameter is a 16-bit Red-Geen-Blue (RGB) integer, in the example code above the words YELLOW, CYAN, RED, and BLUE are defined as integers in the TFTv2.h file.

The TFT Touch Shield"s backlight is on by default since its control circuit is directly powered by the 5V pin. If, however, you wish to control the backlight"s on/off state using the Arduino Digital I/O pin 7, a simple modification will have to be made:

Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with the 3D printer. Although it"s not such fine as you think, even a little bit clunky, it"s still very cool. That is the point this is a cell phone made by ourselves.
