The TFT display is a kind of LCD that is connected to each pixel using a transistor and it features low current consumption, high-quality, high-resolution and backlight. This 2.8-inch full color LCD has a narrow PCB display. The resolution is 320×280 pixels and it has a four-wire SPI interface and white backlight.

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.

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).

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();

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.
