Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 3.2"TFT Touch Shield with Libraries, Examples.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.

※ Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule.

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.

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.

SainSmart 3.2" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design.

3.2"" TFT LCD module with 40 IO, it is more than a LCD module and colleagues also includes an SD card slot, whether with touch function. (Here we are with touch screen function module)

It all started when I saw a SainSmart 3.2” 320 x 240 TFT LCD display with built-in display controller, touch screen controller, and SD card interface for sale on Amazon for $16. I already had an Arduino Uno on hand, so connecting these two devices seemed like a natural thing to attempt. Having never connected an LCD display to a microcontroller before, I was anxious to do so. Finding a well written driver library (see Resources) for this display put the icing on the cake, so I got to work wiring things together. In an afternoon, I wired the LCD display to the Arduino, downloaded and installed the UTFT driver on my Mac, and compiled and ran the demos that came with the driver. I was amazed at how easy this came together, and I had the basis for my personal light show running in less than a day.

After seeing the demos, I started thinking about what else I could make this LCD display do. So, I started pulling out code I had written over the years and began porting it to the Arduino Uno. First off was the Mandelbrot set. While the code worked and the results were beautiful, it took a full five minutes to generate which was okay because I wasn"t in a hurry. The long generation time was not too surprising because the Mandelbrot set requires a lot of floating point calculations which are time-consuming on any eight-bit processor.

Equally as pretty and in general less processor-intensive are the calculations of Julia sets. So, this is what I tried next, and some of the images produced took my breath away. I was starting to think this hardware combination had some merit, so one thing lead to the next and pretty soon I had about 16 different display patterns running including: the Mandelbrot set, Julia sets, plasma patterns, numerous spirograph patterns, star burst patterns, concentric squares and circles, and much more.

Since having this device on my desk/bench, I have found it helps me think. When I get stuck on something I"m working on, I glance over at the display for a few minutes taking my mind off of things which sometimes helps in finding a solution. For this reason, I"ve decided to call this device a “Desktop Contemplator.”

Once you"ve gathered the required components, wiring the Uno to the LCD display is easy, though rather tedious due to the number of wires involved. A lot of wires are required because I used a 16-bit interface between the Uno and the LCD display. I chose this instead of an eight-bit or serial interface in the interest of performance.

A drawback to using the 16-bit interface with the Arduino is that it uses up every available I/O pin. This means neither the touch screen component nor the SD card interface available on the LCD display"s PCB (printed circuit board) can be used. Luckily, neither were necessary for this application.

All required connections between the Uno and the LCD display are shown in Table 1 and the LCD display connector pinout is shown in Figure 1. Take your time when doing this wiring and double-check your work when you"re finished before applying power.

As I was writing this article, I discovered SainSmart also sells an assembly consisting of an Arduino Mega2560, a shield for connecting the LCD display to the Arduino, and the same LCD display we are using here. They officially call it the SainSmart Mega2560 Board+3.2 TFT LCD Module Display+Shield Kit for Atmel Atmega AVR 16AU Atmega8U2 and it’s available from their website (see Resources). If you were to buy this assembly, you could use it without having to do any wiring at all. A minor software change (to be described shortly) is required, however, to run the Contemplator sketch on this hardware.

A major advantage to using this hardware is that there are many more I/O lines available which allow access to the touch screen controller and the SD card interface if these are important to your application. Additionally, the Mega2560 has four times the RAM (8K) and eight times the Flash (256K) which would allow many more display patterns to be developed.

The Contemplator requires two pieces of software for its operation. The first is the UTFT driver library for the LCD display and the second is the Arduino sketch I wrote called Contemplator.ino (see Resourcesand the downloads for this article).

Once you have the hardware wired up, the UTFT driver installed, and the Contemplator sketch available, you can download the sketch via the Arduino IDE and watch the magic happen. You don"t need to understand how the Contemplator sketch works in order to use and/or appreciate it.

If, however, you would like to know how the various graphic display patterns work or if you would like to change the sketch to add new display patterns or remove existing ones, more in-depth knowledge is required. The best way to gather this knowledge is by knowing how the Contemplator is supposed to work and by studying the Contemplator sketch.

As mentioned in the introduction, the Contemplator provides 16 display patterns for our viewing pleasure. Code in the sketch randomly selects which display pattern is shown and makes sure that all 16 patterns are displayed before any are allowed to repeat. The flags array in the code controls this.

A display pattern will be shown for either 30 seconds or the time it takes for the pattern to generate and display itself — whichever is shorter. If display pattern generation takes less than 30 seconds, some patterns will repeat so you will see them numerous times in succession.

The software was designed so that the individual display patterns do not need to concern themselves with display duration timing. All they need to do is to call the function checkForTimeout()periodically and if their display time period has expired, their execution will come to an end and the next display pattern will be invoked. The setjmp and longjmp mechanism built into the Arduino programming language allows this to work. Google these terms if you are interested in how.

Another interesting aspect of the code is the use of an array (called patternFunctionsin the code) of function pointers to the display pattern routines. A display pattern is selected and executed via an index into the array with this single line of code:

A typical display pattern routine is shown next. This code draws a series of connected line segments until its time is up. Any display pattern routines you write would resemble this code:

As mentioned, a software change is required to the Contemplator.ino sketch if a SainSmart Mega2560 is used instead of an Arduino Uno. The normal instantiation of the LCD driver for an Uno is as follows:

I also wanted to make it structurally sound so it would last a long time. To this end, I epoxied four 3/4” wooden dowels (1/8” in diameter) to the top corners (component side) of the Arduino PCB. I then inserted .1” male header pins into all of the Arduino"s female headers, to which I would solder wires from the LCD display"s connector.

I then epoxied the other end of the four dowels glued to the Arduino onto the back of the LCD display"s PCB, making sure to miss all of the components and to orient the Arduino so the USB connector was opposite to the connector on the LCD display. I made sure I left enough space so I could solder to the display"s connector pins.

I wrapped this assembly with a rubber band while the epoxy dried. Once the glue cured and the assembly was stable, I soldered short wires from the display connector to the appropriate header pins on the Arduino as specified in Table 1.

The cutout for the LCD display in the front panel was sized so that the actual display fit through the cutout but the display"s PCB did not. During final assembly, I put a small amount of silicon caulking onto each corner of the display"s PCB and pressed the display into the cutout. Once dried, the silicon holds the display/Arduino assembly in place, but it can easily be removed for servicing.

At this point, I downloaded code into the Arduino to make sure everything was still working. Once I was satisfied all was well, I placed some 3/8” foam on the back of the Arduino"s PCB, put the rear panel in place, and screwed it on. The foam provided just enough thickness to gently hold the display/Arduino assembly in place.

Finally — because the frame around the LCD is white — I cut pieces of black cardboard and glued them onto the white frame to cover it. With that, the Contemplator was complete and has been sitting on my workbench/desk ever since.

Flashing LCD displays and other blinky things are not for everyone. For me, having a personal light show on my desk is a treat. There is something neat about have a little device with its one purpose in life to continually generate images like these to calm and amaze me.

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 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.

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.
