open-smart 2.2 tft lcd connection supplier

Hi, I bought a similar screen on eBay as francosalda - stupid I realise with hindsight, and next time I"ll get a standard screen with Arduino support. In the meantime, I"d like to get this one working if possible. The differences between my screen and that of francosalda is that mine is described as an Open-Smart 2.2 TFT", and in the back it says: "Driver IC: ILI9225". Other than that, it looks identical, and it has the same number of pins and they are marked exactly the same. I"ve tried the ILI9225 library, but can"t get it to work. I suspect that mine isn"t a real ILI9225 screen, as I"ve noticed from pictures that ILI9225 screens have an SD card slot in the back, which mine doesn"t. So, seeing as mine looks more like francosalda"s, I"m trying the steps in this thread.

I"m using it on an Arduino Uno, which does have a 3.3V output. I"ve wired the pins as set out by francosalda and have installed the MCUFRIEND_kbv library. When I run the "diagnose_tft_support" example, I get the following output in the Serial Monitor:

I"ve tried forcing the ID to 0x9481 [tft.begin(0x9481)] in some of the example sketches as suggested in the above output, but still don"t get any output on the screen. The screen just remains a blank white. Any help will be greatly appreciated!

No! For about the price of a familiar 2x16 LCD, you get a high resolution TFT display. For as low as $4 (shipping included!), it"s possible to buy a small, sharp TFT screen that can be interfaced with an Arduino. Moreover, it can display not just text, but elaborate graphics. These have been manufactured in the tens of millions for cell phones and other gadgets and devices, and that is the reason they are so cheap now. This makes it feasible to reuse them to give our electronic projects colorful graphic displays.

There are quite a number of small cheap TFT displays available on eBay and elsewhere. But, how is it possible to determine which ones will work with an Arduino? And what then? Here is the procedure:ID the display. With luck, it will have identifying information printed on it. Otherwise, it may involve matching its appearance with a picture on Google images. Determine the display"s resolution and the driver chip.

Find out whether there is an Arduino driver available. Google is your friend here. Henning Karlsen"s UTFT library works with many displays. (http://www.rinkydinkelectronics.com/library.php?i...)

Load an example sketch into the Arduino IDE, and then upload it to the attached Arduino board with wired-up TFT display. With luck, you will see text and/or graphics.

We"ll begin with a simple one. The ILI9163 display has a resolution of 128 x 128 pixels. With 8 pins in a single row, it works fine with a standard Arduino UNO or with a Mega. The hardware hookup is simple -- only 8 connections total! The library put together by a smart fella, by the name of sumotoy, makes it possible to display text in multiple colors and to draw lines.

Note that these come in two varieties, red and black. The red ones may need a bit of tweaking to format the display correctly -- see the comments in the README.md file. The TFT_ILI9163C.h file might need to be edited.

It is 5-volt friendly, since there is a 74HC450 IC on the circuit board that functions as a level shifter. These can be obtained for just a few bucks on eBay and elsewhere, for example -- $3.56 delivered from China. It uses Henning Karlsen"s UTFT library, and it does a fine job with text and graphics. Note that due to the memory requirement of UTFT, this display will work with a standard UNO only with extensive tweaking -- it would be necessary to delete pretty much all the graphics in the sketch, and just stay with text.

This one is a 2.2" (diagonal) display with 176x220 resolution and parallel interface. It has a standard ("Intel 8080") parallel interface, and works in both 8-bit and 16-bit modes. It uses the S6D0164 driver in Henning Karlsen"s UTFT library, and because of the memory requirements of same, works only with an Arduino Mega or Due. It has an SD card slot on its back

This one is a bit of an oddball. It"s a clone of the more common HY-TFT240, and it has two rows of pins, set at right angles to one another. To enable the display in 8-bit mode, only the row of pins along the narrow edge is used. The other row is for the SD card socket on the back, and for 16-bit mode. To interface with an Arduino ( Mega or Due), it uses Henning Karlsen"s UTFT library, and the driver is ILI9325C. Its resolution is 320x240 (hires!) and it incorporates both a touch screen and an SD card slot.

Having determined that a particular TFT display will work with the Arduino, it"s time to think about a more permanent solution -- constructing hard-wired and soldered plug-in boards. To make things easier, start with a blank protoshield as a base, and add sockets for the TFT displays to plug into. Each socket row will have a corresponding row next to it, with each individual hole "twinned" to the adjacent hole in the adjoining row by solder bridges, making them accessible to jumpers to connect to appropriate Arduino pins. An alternative is hard-wiring the socket pins to the Arduino pins, which is neater but limits the versatility of the board.

In step 5, you mention that the TFT01 display can"t be used with the UTFT library on an Arduino Uno because of its memory requirements. It can - all you have to do is edit memorysaver.h and disable any display models you"re not using.

Tho I realize this is quickly becoming legacy hardware, these 8,16 bit parallel spi with 4 wire controller 3.2in Taft touch display 240x380. It has become very inexpensive with ally of back stock world wide so incorporating them into any project is easier then ever. Sorry to my question. I’m having difficulty finding wiring solution for this lcd. It is a sd1289 3.3 and 5v ,40 pin parallel 8,16 bit. I do not want to use a extra shield,hat or cape or adapter. But there’s a lot of conflicting info about required lvl shifters for this model any help or links to info would be great .. thank you. I hope I gave enough information to understand what I’m adoing

The TFT display is a kind of liquid crystal display that is connected to each pixel using a transistor and it features low current consumption and backlight. This 2.2-inch full color LCD has a narrow PCB screen. The resolution is 320×280 pixels and it has a four-wire SPI interface and white backlight.

If your applications are directly connected to a PC, a cellphone, or Raspberry Pi, and you have enough space to insert a board to input video, Panox Display can provide customized Controller/Driver boards with input connections for VGA, HDMI, DVI, DP, Type-C video input, MIPI, RGB, LVDS, and eDP.

Look at the back of the 2.2inch TFT LCD Display Module Touch Screen Shield from OpenSmart. These are not the same pins we saw with the 2.4inch ILI9341 which followed the MCUFRIEND layout.

Let"s go through the pinouts and see what they are. The UART and I2C ports are available and they are wired out to the face of the shield. A few pins are unused. The data leads for the LCD screen are spread about. Schematics say the SPI pins are standard.

When I ordered my board the vendor gave me a link to GoogleDocs where I downloaded a zip file. The Zip file was for more than one product. Inside the ILI9225 shield folder were two arduino libraries for Arduino TouchScreen and UTFT.

When you restart your Arduino IDE there will be menus for TouchScreen and UTFT added to your examples. Look inside the examples folder in the library and you will see several TFT screen products are listed.

Let"s open the example TFT_2in2_176x220_Demo and compile to make sure everything is working. Error messages do contain useful information about what you have to repair.

Upload the sketch and the Demo program will run on the screen. There are two more example sketches for our shield: TFT_2in2_Show_bmp and TouchScreen_2inch_9225.

Let us try another sketch. This one is very basic and you should change parameters around to see what you get. Change colours, change locations.// Demo of Graphics on OpenSmart ILI9225 2.2inch shield 176x220

We are using release 2.78 of the UTFT library from 2014. OpenSmart has modified the library to support their boards. That is why they gave me a download.

The UTFT library was produced by Rink Dink Electronics and you can download the latest release 2.83 from 2018. Unfortunately, this version of the library will not work with our board. It does not have files to work with the ILI9225. But we can still use the examples if we modify them.

Open the sketch UTFT_ViewFont and find the constructor. Comment out the line UTFT myGLCD(ITDB32S, 38, 39, 40, 41) because it is for a different display type on a different Arduino board.

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.

Today, we are going to Interface 2.4 inch TFT LCD Shield with Arduino. By using this color TFT LCD shield we can show characters, strings, blocks, images etc on the color TFT LCD. And we can use this TFT Shield in many applications like:  Security System, Home Automation, Games etc.

Interfacing TFT LCD with Arduino is very easy. We only need to have an Arduino Board & a 2.4 inch TFT Shield in hardware part and Arduino IDE & TFT Library in software part. Many libraries are available on the Internet, for TFT Shield to operate, but different TFT LCDs have different inbuilt drivers. So first we need to identify the driver of TFT and then install a suitable library for that. Here we are using 2.4 inch TFT Shield having ili9341 driver. Link, for downloading the Library for given TFT, is given in ‘Steps’ below. Check this for simple LCD interfacing with Arduino.

ER-TFT022-1 is 240x320 dots 2.2" color tft lcd module display with ILI9341 controller,optional capacitive touch panel with controller FT6236U and resistive touch panel,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-bit,9-bit,16-bit,18-bit parallel,3-wire,4-wire serial spi 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 2.2"TFT 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.

The DT022BTFT uses the same connections as the DT022CTFT, with the exception of the backlight (which has connections shown in the Displaytech datasheet).

The 2.2" display has 320x240 color pixels. Unlike the low cost "Nokia 6110" and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display is a true TFT! The TFT driver (ILI9340 or compatible) can display full 18-bit color (262,144 shades!). And the LCD will always come with the same driver chip so there"s no worries that your code will not work from one to the other.

The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. We also had a little space so we placed a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card. The microSD card is not included, but you can pick one up here.
