Hi guys, over the past few tutorials, we have been discussing TFT displays, how to connect and use them in Arduino projects, especially the 1.8″ Colored TFT display. In a similar way, we will look at how to use the 1.44″ TFT Display (ILI9163C) with the Arduino.

The ILI9163C based 1.44″ colored TFT Display, is a SPI protocol based display with a resolution of 128 x 128 pixels. It’s capable of displaying up to 262,000 different colors. The module can be said to be a sibling to the 1.8″ TFT display, except for the fact that it is much faster and has a better, overall cost to performance ratio when compared with the 1.8″ TFT display. Some of the features of the display are listed below;

TheTFT Display, as earlier stated, communicates with the microcontroller over SPI, thus to use it, we need to connect it to the SPI pins of the Arduino as shown in the schematics below.

Please note that the version of the display used for this tutorial is not available on fritzing which is the software used for the schematics, so follow the pin connection list below to further understand how each pin of the TFT display should be connected to the Arduino.

When connecting the display, ensure that has a voltage regulator (shown in the image below) before connecting it directly to the 5v logic level of the Arduino. This is because the display could be destroyed if the version of the display you have does not have the regulator.

In order to allow the Arduino to work with the display, we need two Arduino libraries; the sumotoy TFT ILI9163C Arduino library which can be downloaded from this link and the popular Adafruit GFX Arduino library which we have used extensively in several tutorials. Download these libraries and install them in the Arduino IDE.

For today’s tutorial, we will be using the bigtest example which is one of the example codes that comes with the sumotoy ILI9163C Arduino library to show how to use the TFT display.

The example can be opened by going to File–>Examples–>TFT_ILI9163c–>bigtest as shown in the image below. It should be noted that this will only be available after the sumotoy library has been installed.

Next, we define some of the colors that will be used along with the corresponding hex values. If you’ve gone through any of our previous tutorials where we used the Adafruit GFX library, you would have noticed that this code contains a lot from the GFX library and it should be easier for you to follow.

Next, an object of the ILI9163c library named “display” was created with CS and DC parameter as inputs but due to the kind of display being used, we need to include the pin of the Arduino to which the A0 pin of the TFT display is connected which is D8.

With this done, we move to the void setup() function. Under this function, we issue the commands that initialize the display then create a time variable updated by millis, after which we issue a command to clear the screen and display some random text on it.

Some of the functions which perform actions ranging from displaying fastlines, drawing rectangles etc are then called with a delay after each function so the text or graphics stays long enough on the screen to be visible.

Up next is the void loop function. The void loop function also calls some of the same functions called under the void setup() function to display circles, rectangles etc including the testline function which is essentially used to test the screen.

With the libraries installed, open an instance of the Arduino IDE, open the examples as described initially, don’t forget to make the A0 pin (D8) correction to the code then upload to the Arduino board. You should see different kind of text and graphics being displayed on the screen. I captured the screen in action and its shown in the image below.

That’s it for this tutorial guys, what interesting thing are you going to build with this display? Let’s get the conversation started. Feel free to reach me via the comment section if you have any questions about the tutorial.

I have a 128x128 ST7735 display that I"m driving with a Seeeduino Xiao (SAMD21). I"d like to draw static fuzz, of the type found on old televisions - i.e. random pixels or squares of black and white.

Similar with libraries... I"m not married to any library in particular. I"ve experimented with a couple, but most of the trials were with the Adafruit_GFX + Adafruit_ST7735.h

(EDIT: And going even further, I"m open to using a board with a different TFT driver if it helps, provided similar pricing and availability and drivers for the samd21.)

Another technique I plan to try next is write a bitmap image of pre-rendered static to the screen (since it seems to be faster than doing random() + drawing a pixel 128x128 times), then just use every spare cycle to write a random pixel. I"m guessing it will look a bit too static in appearance, but I"ll give it a try.

The sparse docs (Getting Started with Seeed Studio XIAO SAMD21 - Seeed Wiki) seem to imply it has hardware SPI support, and I followed their pin recommendations. But perhaps this is another thing to dig into. I have another samd21 board (adafruit itsybitsy) with known hardware SPI support that I can try to rule out SPI issues.

I created a sketch for the Uno with a nameless 320x240 TFT display shield, ILI9341 controller, using the tft.writePixel (x,y,COLOR) instruction, combined with the random function.

I stick with the 105x105 resolution, it looks great, I would center that surface in the 128x128 px space, leaving a black or gray frame as the background

Actually I would like on my 320240 TFT bigger grains (22 blocks of pixels) creating the impression of random (pseudo)noise. That would imply the use of small bitmaps or some complicated stuff remembering previous positions of displayed pixels; I am not sure whether my Uno is fast enough to create a realistic effect. Any suggestion?

The cell phone camera is not synchronized to the speed with which the pixels appear on the screen, this generates a sloping cross band and an apparent increase in speed, which do not really exist in the TFT. Keep in mind that 128x128 = 16,384 pixels are drawn in each step

The ESP32 manages 96fps when every pixel of the 128x128 display is updated per frame, not bad for a $5 processor board. This is at a 26.66MHz SPI clock, so the theoretical maximum is 102fps with no looping delays. This is clearly faster than an old TV frame rate so delays could be added, other code run or a lower SPI clock rate used.

With four bright white LED backlight and 240 x 320 pixels with individual RGB pixel control, this colour 2.8in. TFT display features a resistive touchscreen for fingertip detection across the entire screen surface. The workload is lifted from the microcontroller by a built-in controller equipped with RAM buffering, and the display board has two modes: 8-bit and SPI.

The Adafruit 2.8in. TFT LCD Touchscreen Display brings QVGA graphics to your next project using only 5 x SPI pins or 12 x GPIO pins if you can spare them. The screen is bright with a 4-LED backlight and can display 18-bits of colour (262,000 colours). There"s a display controller built in so your microcontroller doesn"t need to get involved in refreshing the screen, it just has to write the pixels once then it can move on to other tasks. SPI mode uses less pins but is slower while 8-bit mode uses more pins and is faster, the choice is up to you. Adafruit have software and tutorials to support you whichever mode you decide to use, see the links below. The board also has a micro-SD card socket that you can use to store files and images.

Imagine what you could do with this if only it had a touch screen. Of course you don"t need to imagine, because the display has a built-in resistive touch screen. Because it uses resistance to detect touch, this screen will work with a finger, a stylus, the non-writing end of a pen or even a gloved finger. Anything that can put pressure on the screen will register a touch. The touch screen uses a further 2 x digital pins and 2 x analogue inputs regardless of whether you use SPI or 8-bit mode to drive the display.

Visit https://learn.adafruit.com where Adafruit provide a free tutorial for the Raspberry Pi, and another tutorial for the Arduino. They also have an open source library to drive the display in 8-bit mode, and another to use SPI mode. Please note that while the screen is capable of 18-bit colour, the Adafruit code uses 16-bits for efficiency. It"s highly unlikely that you"ll ever notice any difference.

This lovely little display breakout is the best way to add a small, colorful and bright display to any project. Since the 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 1.44" display has 128x128 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 (ST7735R) can display full 16-bit color using our library code.

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.
