SainSmart 3.2" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and mutilfunctional module for your project.The Screen include a controller SSD1289, it"s a support 8/16bit data interface , easy to drive by many MCU like STM32 ,AVR and 8051. 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.
There is built-in SD card slot in the shield, so we can use it to upload images. But the images need to be converted RAW format first.You can use the tool here. SD libraries need to be preinstalled for displaying the image.
Note:The SD library only can be use in version arduino-00xx and the library only supports FAT16 fomatted SD card up to 2GB, so you need to fomat your SD card to FAT16. 4GB FAT16 fomatted SD card is tested not working. Long file names are not supported. Keep your file names compliant with 8.3 standard.

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.
Over the past year, I"ve ordered 47 of these SainSmart LCD displays. For a while, they had a good thing going, but in the Autumn of 2015, they changed their manufacturing and have utterly messed up this device. The first six that I ordered in the Summer of 2015 worked perfectly. But of the 41 devices that I"ve ordered after the change, 40% have failed right out of the box... 6 won"t power up at all, 4 have screen flicker, 2 the touch doesn"t work, 1 the LCD pixels were misaligned and 1 had a cracked screen.
What happened? Besides utter lack of quality control (these displays were obviously never tested), SainSmart changed the LCD screen hardware. Instead of using the LCD screen that would fit properly on the TFT_320QVT PCB (see pictures), they chose a slightly thinner, narrower LCD screen that normally fits the TFT_320QDT PCB. (notice the one letter difference). The problem is that the new screen DOES NOT FIT properly into the pin holes on the PCB and has a nasty habit of falling off (see pics). They obviously realized this at the factory, and rather than re-ordering the correct screens, they just tried to force them to stay on with double sided tape. But that hasn"t worked well. Many of my screens had fallen off by the time I received them! But because I own a business that uses these things and I didn"t know at the time that I could find alternative suppliers for this part, my work-around was to glue them into the best position possible using a hot glue gun. What a pain!
Moral of the story: Don"t order any of these from SainSmart LCDs until they have accepted they have screwed this up and fixed this problem. I suspect they will comment on this review once that has happened and I"ll make modifications to this review to let you know when the problem is fixed. Until then, BUYER BEWARE. And, any other SainSmart product that includes this 3.2" is very likely going to include this same problem - including the shield + LCD and Mega2560 + shield + LCD.
That all said, when this thing works, it works really well. I am satisfied with resolution and the touch is responsive. I use it in the product that our company sells. Just don"t get it from Sainsmart - for now. There are alternative suppliers.
* The screen IC driver comes in two flavors out there: SSD1289 and ILI9341. They both work, but the software configuration is slightly different. So, either use one or the other - or expect to somehow auto-detect which one connect to your Mega2560 (not possible directly) and then code for both possibilities. As far as I can tell, the SSD1289 is being phased out for the now more common ILI9341. I"ve ordered this device from a number of sites, but unfortunately they often list the item as SSD1289, but it arrives as a ILI9341. If you are new to this, my advice is to go with the ILI9341 driver. The UTFT library was updated in the Summer of 2016 to accommodate this newer driver. Another reason to pass on this Sainsmart device is that it uses the SSD1289 driver. How can you tell the difference? The model for SSD1289 is TFT_320QVT and the model for ILI9341 is TFT_320QVT_9341. Unfortunately, ads for these devices often have the wrong model number displayed!

And no, you can"t reformat a larger SDHC card down to 2GB and get it to work. Won"t work. You can however get a 2GB or 4GB SD Card (not SDHC) and it"ll work fine. You may see some documentation suggesting a 2GB limitation, but it"s really 4GB as long as you don"t use a SDHC card. Did I mention, do not use SDHC?

I have the afore mentioned display and i"ve been looking for help getting it up and running for some time. I found another person in the same situation as me, please help us:
I have been scouring the web to find all different bits of information for the Sainsmart 2.8 inch touch display with no avail on instructions on how to actually make it work.
I assumed that being it has a compatible 40 pin header that all I needed to do was put a 40 pin cable on it and install software and the os would pick up the display by default.
SainSmart 2.8" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and mutilfunctional module for your project.The Screen include a controller ILI9325, it"s a support 8/16bit data interface , easy to drive by many MCU like arduino families,STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is XPT2046 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.
Voltage type: 5v or 3v voltage input voltage,input is selectable. Because TFT can only work under 3.3 V voltage, so when the input voltage VIN is 5V, need through the 3.3 V voltage regulator IC step down to 3.3V , when the input voltage of 3.3 V, you need to use the zero resistance make J2 short , is equivalent to not through the voltage regulator IC for module and power supply directly.(Click here)
So I contacted them and they sent me out the documentation etc. As I read all the documentation there was not one mention of how to get the PI to recognize the display. So I contacted them again and the response was to try element14.com. I went there and again no avail.
I am hoping that this is the last stop and that someone might have instructions on how to get the pi to recognize the display. Currently when hooked up the screen lights up, but that is about it, no output what so ever. The only output is what is going through the hdmi port to the tv.
Terdapat lebih banyak lagi untuk membina sebuah LCD daripada sekadar mencipta satu kepingan kristal cecair. Gabungan empat fakta menjadikan LCD mungkin:
Kesederhanaan relatif jalur cahaya projektor LCD membawa kepada kelebihan lain - ia menghasilkan imej yang lebih tajam. Ini bukan untuk mengatakan bahawa projektor lain adalah kabur, walaupun. Ia hanya bermakna apabila imej LCD dan DLP dijangka bersebelahan antara satu sama lain, imej LCD akan menjadi sedikit crisper, terutamanya dengan jenis teks dan kandungan grafik yang mungkin digunakan para pembentang perniagaan.
Selama bertahun-tahun, manfaat kos LCD telah menurun secara perlahan berbanding dengan projektor DLP. Walau bagaimanapun, projektor LCD masih kekal sedikit lebih murah. Sebagai contoh, sementara projektor LCD mudah alih yang menyokong resolusi 1024-dengan-768 piksel dan 2600 lumen output cahaya membawa harga runcit yang dicadangkan sebanyak $ 649, sebuah projektor DLP yang setanding, walaupun dengan 600 output cahaya lumen yang lebih sedikit, kos $ 669. Oleh kerana projektor LCD tidak memerlukan roda warna bermotor seperti projektor DLP, mereka mempunyai bahagian yang lebih sedikit dan boleh menjadi lebih murah untuk menghasilkan. Terdapat juga pasaran yang kompetitif untuk pembuatan panel LCD, manakala unsur cahaya DLP dibuat oleh hanya satu syarikat: Texas Instruments.

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.
