Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 2.8"TFT Touch Shield with Libraries, EXxamples.Schematic Diagram for Arduino Due,Mega 2560 and Uno . For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

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.

Add some sizzle to your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection and acapacitivetouchscreen. 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 acapacitivetouchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This shield is the capacitive version as opposed to theresistive touchscreenwe 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 I2C 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 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, 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 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!

After that I have been able to connect the touch-sensitive part of the screen as well, and it reads x+, x-, Y+ and y- fairly well using Touch-Screen-Library (https://github.com/adafruit/Touch-Screen-Library) (I still have to some more calibration though).

I have been running into problems when I wanted to actually display something on the screen using TFT LCD library (https://github.com/adafruit/TFTLCD-Library) (and the GFX library (https://github.com/adafruit/Adafruit-GFX-Library))...

Connect the seventh pin RST (Reset) to the Arduino Reset line. This will reset the panel when the Arduino is Reset. You can also use a digital pin for the LCD reset but this will save us a pin.

It should be 0x9328 or 0x9325 so if you see something like 0x8328 that means that the D8 pin is not wired correctly and if you get 0x9228 then pin D0 is not wired correctly.

Adafruit is also selling a shield version of you display and I think you can use this to verify you pin assignment. With this: https://github.com/adafruit/TFTshield/blob/master/schem.png

and this: http://arduino.cc/en/uploads/Main/ArduinoUno_R3_Front.jpg you can figure out how the pin assignment is supposed to work with a shield/UNO. now you need to either replicate or map this to you Teensy.

I just got my teensy3 displaying the graphicstest on my LCD. Your description here of how to do it was just fine, though it took me a couple of tries to get the wiring right (my fault, though)

I got this going as well thanks to your guidance. While I was fiddling with the pinouts etc. in pinmagic, I did a couple of other things, in Adafruit_TFTLCD:

inline Adafruit_GFX& operator() (uint8_t x, uint8_t y,uint16_t c) {setCursor(x,y); setTextColor(c); return *this;} //use along w Streaming.h to support: tft(col,line,color)<<"a="<

inline Adafruit_GFX& operator() (uint8_t x, uint8_t y,uint16_t c,uint8_t s) {setCursor(x,y); setTextColor(c); setTextSize(s); return *this;} //use along w Streaming.h to support: tft(col,line,color,size)<<"a="<

http://www.ebay.de/itm/New-2-4-inch-TFT-LCD-Module-display-240-x-320-Screen-ILI9325-with-touch-pen-/281090515728?pt=UK_BOI_Electrical_Components_Suppl ies_ET&hash=item41724ce310

They are not using the current library, as you guessed. I tried patching pin_magic.h with the teensy 3 mods, but more is required for the current TFTLCD library. The library now supports DUE, and the constructor does a lot of work mapping the control pins into port register access for set/clear operations. Maybe the teensy equivalent would be to use

For the hacked together version I"ve been using and testing on a 3.1, the __AVR__ style of pin/port mapping from the new library seems to be what I"ve been using. csPort = portOutputRegister(digitalPinToPort(cs)); etc

And I measured 32.7ma at 3.3v for the TFTLCD, so I powered it from the teensy 3 3.3v pin. This is on older Adafruit TFTLCD, http://www.adafruit.com/products/335

OK, maybe I"m confused, but does that library drive the Adafruit display in 8-bit mode (as described at https://learn.adafruit.com/adafruit-2-dot-8-color-tft-touchscreen-breakout-v2/8-bit-wiring)? The TFTLCD library has the disadvantage of needing more pins, but my impression was that it could achieve a higher throughput of data to the display, or am I mistaken in that as well?

Well, this is awkward. I had a 2.8" ILI9325 screen from Adafruit working on a Teensy 3.0 a couple of years back. I just tried to rebuild the code for that and I seem to have lost some files. Specifically I"m looking for the right Adafruit_TFTLCD library (well, I think that"s all I"m looking for). The current library from Github doesn"t compile with a Teensy3, and I recall I had to edit the pin_magic file as per ZTiK.nl (earlier in this thread). But the later files from Github look different now. I don"t seem to be able to go back to an earlier branch on Github.

I can see Paul has posted an ILI9341_t3 library, but mine is an ILI9325. Has anyone got a working copy of the library that works with my combination posted somewhere? I"d rather not upgrade the hardware at this stage, the problem I have is software.

Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful! 240x320 pixels with individual RGB pixel control, this 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.

Of course, Adafruit wouldn"t just leave you with a datasheet and a "good luck!". For 8-bit interface fans they"ve written a full open source graphics library that can draw pixels, lines, rectangles, circles, text, and more. For SPI users, there is a library as well, its separate from the 8-bit library since both versions are heavily optimized. There is also a touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it.

If you are using an Arduino-shaped microcontroller, check out the TFT shield version of this same display, with SPI control and a touch screen controller as well

Luego, dado que el escudo TFT no podr usar la interfaz ICSP, conect los puentes como dice en wiki. The headers on the side of the screen with the small blue tab and arrow should be the ones that attach to the board. There is a socket on the front of the Esplora for the screen. Do peer-reviewers ignore details in complicated mathematical computations and theorems? The code is the same as the exemple but modified with my pins: miso 12 (brown) The Chip select must be connected to pin 10 of the Arduino UNO, as shown in the figure. See Step 8]. An alternative is hard-wiring the socket pins to the Arduino pins, which is neater but limits the versatility of the board.

The first part of this three-part series discussed common touchscreen technologies and their typical use-cases. Then, the second part investigated a few readily available and affordable touch display options for makers and hobbyists. This article documents how to get started with one of the recommended Arduino-compatible 2.8” resistive touchscreens from part two.

The TFT display I use contains a resistive overlay, which allows users to control an Arduino-based project with touch inputs. The display controller that comes with the touchscreen supports a few different communication methods. However, I’ll only outline two of them as I find these to be the most useful. The first method uses eight parallel communication lines to transmit pixel data from the Arduino to the display. I recommend using this method in multimedia applications where the Arduino needs to transfer a lot of pixel data.

You have to install two libraries before you can send image data to the TFT display. First, use the Arduino IDE’s built-in library manager to download the Adafruit ILI9341 library. This package handles low-level communication between the Arduino and the display controller IC. Then, download the Adafruit_GFX library. The second library contains helpful code for drawing graphics primitives such as simple shapes and text. I recommend you read this article if you don’t know how to use the library manager in the Arduino IDE.

This short test program first initializes the TFT display in the setup()-function. Then, I defined a few helper methods. The resetAndClearScreen()-method resets the display’s rotation and erases all previously drawn pixels. The next function is drawIntroText(). It prints a short status message in the top left corner of the display. Lastly, drawTouchButton() creates a rectangle at the specified position with the given width and height. Then, the method places a string at the center of the previously drawn rectangle. As the name suggests, I’ll later use these rectangles to detect user inputs. The loop()-method refreshes the screen twice a second. But because there’s no interactivity built into the program yet, users can’t change what the screen displays at this point.

To use the resistive touch capabilities of this display, download the Adafruit_TouchScreen library using the Arduino IDE’s built-in library manager. The example code from above prints a few lines of text and then draws two touch buttons. Next, we’ll have to detect when a user presses one of the buttons. If that happens, the Arduino should refresh the screen and draw all the components using different colors. Therefore, I added the following method to detect whether a user touched one of the buttons:
