SainSmart 3.2 TFT LCD shield works in 3.3V voltage level and you need to use cables to connect with Arduino Mega. And this shield can help you out of the bothers to use other cables. You just need to plug the module to Mega through this shield.

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.

Reason: The hooks on the backight of ER-TFT032-3.1 is always complained by most customers for inconvenient assembly. So we cancel the hooks in the new version of ER-TFT032-3.2.That"s the only difference for these two versions.

ER-TFT032-3.2 is 240x320 dots 3.2" color tft lcd module display with ILI9341 controller and optional 4-wire resistive touch panel and 3.2 inch capactive touch panel with controller FT6236,superior display quality,super wide viewing angle and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO ARM and Raspberry PI.It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.It supports 8080 8/16-bit parallel,3/4-wire serial interface. FPC with zif connector is easily to assemble or remove.Lanscape mode is also available.

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.

I"m having some strange issues with the SainSmart Mega 2560 R3 + Adapter Shield +3.2 TFT Touch that I bought from SainSmart, and wanted to see if anyone else has experienced the same thing:

This is SainSmart Mega 2560 tft display kit. Simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

I can successfully compile and load any of the example files that come with those libraries and they seem to work OK...until I unplug and restart. When I plug back into the USB cable or to a 12V wall wart, the program runs, and the uC and LCD work OK, but the touch screen is all messed up. I have to recompile and program the board again to get it to work correctly. I"ve tried all of the UTFT examples that use the touch screen and they all do the same thing.

For example, if I compile and load the UTouch_QuickDraw example code, it works OK; I can touch any part of the screen and it draws pixels in the corresponding LCD location. But, if I unplug and restart the uC board the touch screen then only responds to touches to the bottom-right quadrant. And, the data is not correct. As I touch in the bottom-right quadrant, the LCD draws in the top-left quadrant. I did a quick mod to the code to spit out the X/Y values that were being read and, sure enough, in the bottom-right quadrant it would read x = 0 to ~150 and Y = 0 to ~125. Pressing in any other quadrant gave x and y values of -1. If I then recompiled and programmed the board again the everything would work OK; I would get x = 0 to 320 and y = 0 to 240.

The 3.2 inch TFT LCD module is a special design for Raspberry Pi for portable application. It features a 3.2” display with 320x240 16bit color pixels and resistive touch screen. The LCD is well mated with Pi board and interface with Pi via the high speed SPI port, and support console, X windows, displaying images or video etc. It also provides 4 press buttons for user defined functions.

RPi LCD needs to use a SPI interface, but in the original image file of Raspberry Pi, the displayer is driven via a HDMI port. So the original image is not applicable for RPi LCD, and you should install the LCD driver to your Pi or use the Ready-to-use image file provided by Sainsmart,click here.

Download the LCD driver and extract it to your Raspbian OS (e.g. copy the driver to your Pi by sftpor using U disk). Then run the following command via putty:

This LCD can be calibrated using a program called xinput_calibrator which is pre-installed on the offer image. However, it was not pre-installed on original Raspbian OS. So in this case, you should get and install the program manually with

After running these commands, there will be a prompt for four-point calibration shown in the LCD screen. Click the points one by one to finish the touch calibration. Then, the new calibration data will be displayed in the terminal, as shows below. Please get these data for future use.

It is designed with a touch controller in it . The touch IC is ADS7843 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.

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.

I have the same LCD as you do. i was wondering if you could help me with the pinout of the LCD... valdodov has a different lcd and his schematic doesn"t transfer well to the one you have i think. is there a schematic that you could post or tell me where BL_CNT is connected from the 4094s to the LCD?

Thanks for the schematic, I will try and see if this works. if not, its probably some issue with the kernel. Also, if it is due to the kernel... was the kernel files just supposed to be copy pasted into the specific folders? was i supposed to enter anything in the command-line/terminal to get the display to start working?Just need to overwrite what is on your SD card.

Again Thank youEmad, have a look at the updated schematic above… it has the details you need.So i finally assembled all my stuff. But the CE0 is always high which resets the ripple counter off all the time. Is that supposed to be the case?

That"s great and all, but is there a way to push raw image data (bitmap images, video, etc) to this display without making it an active tty/X display? Something that can run headless and have data pushed to it from a remote ssh session, cron job, etc?

Where did you find the pin out for the sainsmart touch screen? We were looking at the following data sheet and it has different pin assignments. Please help us clear up this confusion. Thank you!!the display in your datasheet uses ILI9325 driver chip for the display.

If you cant display the image or you get the same error, I would recheck the wiring. Are you using a breadboard?No /dev/fb1 is not present. We are using a breadboard and just rechecked all of the wiring. The wiring looks good, but we are missing the filter capacitors (can"t get them till tomorrow) would that be the issue? It looks like a few people had this same issue but there is no definitive solution. What exactly is error -22?

We were following the instructions on github/notro/fbtft/wiki but I think I just realized that that"s a different method. So in order to install the kernel/modules should we use the compiled files on Voldadov"s site? If so, how do I copy those drivers? I extracted them to the desktop then did:

I am working for several months with the Raspberry and I also know a few experminete performed. Well me too interested this project. I myself already so bought a 3.2 "touchscreen, but I dunno exactly how to wire the. Could you maybe make a wiring diagram. That would be very nice.For example, with http://fritzing.org/

I was just wondering if the schematic you posted on this page was done in eagle PCB? I am currently using eagle PCB for creating schematic and getting a board layout.

sometimes with blue stripes.... sometimes not all letters only a small stripe..... and agter getting message ???52x21??? screen goes slowly white......I think....... i have killed the display :-p ... ok next one...

-What driver?I am using the same chips and TFT as you are using. The driver i am using is Raspbian. I am using a breadboard but i have checked the circuit multiple times using a multimeter to confirm the connections so i am not sure if that is an issue.

Thanks for the Kernel but on my Pi is nothing to go the Display is not working. I have the Sainsmart 3,2 TFT with the Modul that is in the Video (selfmade) but i find no error in my circuit board it is with 3 74HC4094 and 1 74HC4040 . ? Is there a Kernel that Support this Version with no updates.?

anyone a idea where this vertical flashing lines come from?It has been awhile since I have looked at this version of the display with the above SPI interface.

You can also try and force the 4040 to go faster my connecting it to 5vi found the issue.... above GND is a Pin named "VCC" - it was not connected (and looking at your schematics, it didn"t look like it has to be connected to 5v)
