This lovely little display breakout is the best way to add a small, colorful, and bright display to any project. Since the 5 cm (2.0″) SPI TFT LCD Color Screen Module display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available. The 2.0″ display has 176×220 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 (ILI9225) can display full 18-bit color (262,144 shades!). And the LCD will always come with the same driver chip so there are 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 an 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.

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 order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.

Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

I have bought a ILI9225 2.0" TFT display (8 pin version) and have a problem when using the Nkawu library and SPI hardware. The display works nice using software SPI. SPI hardware does not work. Using the Basic Demo code included in the examples, I noticed that chosing different TFT_brightness have an extrange effect in the pixels drawn. High values (>200) give the screen completely white. However, lower values (<100) start to draw pixels in the screen but the higher this value, the more pixels are missing in the image.
