Great display, nice size and response. If you plan on using an Arduino, please get the shield also. It will save you a ton of time and studying( the 40 pin connector on the back must be broken out in groups and resistors put in that dump to ground. )..

The Mega 2560 clone worked perfectly, the display worked perfectly and the adapter board mated them properly. I had purchased a Seeed 3.2" display at Radio Shack for $49. It had many issues and I returned it and used the money to buy this setup. This display is much faster than the Seeed display and the drivers were very easy to locate and install. Just google "UTFT drivers henningkarlsen" and get all of the UTFT drivers. Henning has several more drivers on his site, go ahead and get them all. They are very easy to use and configure. To use the drivers with this particular board (they are "universal drivers") use this setting for the board type:

The nice thing about SainSmart is that they admit that they are cloning the Arduino boards. Most of the boards available on Amazon are counterfeits and the sellers are not particularly upfront about this. These counterfeit boards exactly copy the Arduino boards, definitely graying the area between legitimacy and piracy. SainSmart clearly marks their boards as clones. I appreciate this honesty in a company, especially when there"s more money to be made by tricking buyers into purchasing counterfeit boards.

I highly recommend this package for anyone wanting to get into Arduino development or wanting a touchscreen. The value is great. Now, I guess I need to hunt down a 7" TFTP display to continue this adventure.

After digging into the touch screen, I found that the UTouch lib had some serious accuracy problems, even after trying to use the calibration utility provided with the library. I re-wrote the lib and now I find that the accuracy of the screen is very good. To re-write the lib, you need to take these factors into account:

Once you know the x and y extremes for the touch screen, simply use the map function to map them to the actual screen coordinates. This gives you a pretty accurate x and y for the display.

The other issue I had was with how the touch screen was sampled. The library code polls the touch screen several times per read and averages the results to get a more accurate reading. In the case of "EXTREME" accuracy, it polls 10 times. The problem with this is that if you lift your stylus during the polling, the last few reads are bogus and throw the entire read off. You can see this happening in the SainSmart demo video that they posted for this device. The symptoms are that pixels get set on the sample paint program way far away from where the stylus is. Not cool! The fix is to only sample the screen if the screen is detecting the stylus as being pressed. You can do this by checking the dataAvailable() before each read in the poll. If there is no data available, don"t do the read.

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.

Well, documentation isn"t really that much fun, so I skipped ahead and extended the breadboard circuit to try it with my Sainsmart 3.2" display which has a 16-bit bus.

Just copy the itdb28fb driver, change all occurences of itdb28fb to sainsmart32fb, add initialization sequence and set_addr_win function. Add section to Kconfig and Makefile and finally add the device to fbtft_device.

Earlier I had extended the FBTFT SD-image with a modified ads7846 driver that can add it"s own device. This makes it ideal for testing different setups.

Sadly this touchpanel didn"t behave as good as the ITDB02-2.8 display. The x values increased as I moved the stylus along the y-axis. The y values was much better.

It was an old version of Henning Karlsen"s library. But, no. The display looked the same. The other displays I have is quite sharp, so this wasn"t good.

Does the Linux driver: ads7846 has built-in calibration?Yes, I know. I have a section about it here: https://github.com/notro/fbtft/wiki/Tou ... alibration

The problem with this display, is that x_min and x_max varies depending on where you are on the panel, whereas y_min, and y_max stays constant. The x values probably need a linear function to calibrate it"s value.

I have not gotten around to measuring frame rate yet, but what I can say so far is that a CPLD based design using a GuzuntyPi (https://github.com/Guzunty/Pi/wiki) driving the Sainsmart 3.2 LCD module will run with a SPI clock of 32MHz.

I have not gotten around to measuring frame rate yet, but what I can say so far is that a CPLD based design using a GuzuntyPi (https://github.com/Guzunty/Pi/wiki) driving the Sainsmart 3.2 LCD module will run with a SPI clock of 32MHz.That"s cool. I had a quick look through the wiki pages, but I couldn"t find anything on how to program the CPLD. Can it be done from the Pi? And does the CPLD socket fit the holes in a breadboard?

Likewise, keyboards plugged into the Pi directly seem to exhibit the sticky key syndrome more often. Has anyone else seen this? Is this expected?Yes, I haven"t had this problem at all until the last FBTFT release. Looking at the commits, I can"t see anything that should cause this since the last FBTFT image (2013-02-09-wheezy-raspbian-2013-05-24-fbtft).

And does the CPLD socket fit the holes in a breadboard? The CPLD socket does have 2.54mm pin spacing, but the pins are arranged in a matrix so would not be compatible with most breadboards, I"m afraid. I use M-F Dupont cables to take signals from the Guzunty to a breadboard (except in this case, where I used F-F Duponts to connect the Guzunty pins directly to the LCD). It is also worth noting that a CPLD can often *completely eliminate* the need for a breadboard (as indeed happened in this case).

Specifically, there are 12 pins left over on the Guzunty which I would like to use as inputs. Since the LCD interface is write only, I would like to transfer the value of these across the SPI0.0 bus as data is clocked out to the display.

Obviously, we don"t want reading these to interfere with the display update, so asynchronously reading the data would get the last clocked in set of pin values.

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.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

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.

This TFT screen is really big (3.2" diagonal), bright (6 white LEDs) and colorful! 240x320 pixels with individual RGB pixel control, which offers a much higher resolution than a 128x64 black and white display. As an added bonus, this screen is already equipped with a resistive touch screen, so you can detect finger pressure anywhere on the screen.

This display has an integrated controller with RAM buffer, so the microcontroller does virtually no work. The display can be used in two modes: 8 bit and SPI. For 8-bit mode, you will need 8 lines of digital data and 4 or 5 lines of digital control to read and write on the screen (12 lines in total). SPI mode requires only 5 pins in total (SPI input data, output data, clock, selection and d/c) but is slower than 8-bit mode. In addition, 4 pins are required for the touch screen (2 digital, 2 analog) or you can purchase and use our resistive touch screen controller (not included) to use I2C or SPI.

We have integrated this screen on an easy to use card, with SPI connections on one side and 8 bits on the other. Both are 3-5V compatible with high-speed level switches, so you can use them with any microcontroller. If you choose SPI mode, you can also use the built-in MicroSD card to display images. (microSD card not included, but any will work)

Of course, we won"t leave you only a technical sheet and a "good luck". For 8-bit interface fans, we have written a complete open source graphics library that can draw pixels, lines, rectangles, circles, text and more. For SPI users, we also have a library, separate from the 8-bit library since both versions are highly optimized. We also have a library for touch screens that detects x, y and z (pressure) and example code to demonstrate all this.
