A wide variety of tft display 1.8 options are available to you, such as original manufacturer, odm and agency.You can also choose from tft, ips and standard tft display 1.8,

Hi guys, welcome to today’s tutorial. Today, we will look on how to use the 1.8″ ST7735  colored TFT display with Arduino. The past few tutorials have been focused on how to use the Nokia 5110 LCD display extensively but there will be a time when we will need to use a colored display or something bigger with additional features, that’s where the 1.8″ ST7735 TFT display comes in.

The ST7735 TFT display is a 1.8″ display with a resolution of 128×160 pixels and can display a wide range of colors ( full 18-bit color, 262,144 shades!). The display uses the SPI protocol for communication and has its own pixel-addressable frame buffer which means it can be used with all kinds of microcontroller and you only need 4 i/o pins. To complement the display, it also comes with an SD card slot on which colored bitmaps can be loaded and easily displayed on the screen.

The schematics for this project is fairly easy as the only thing we will be connecting to the Arduino is the display. Connect the display to the Arduino as shown in the schematics below.

Due to variation in display pin out from different manufacturers and for clarity, the pin connection between the Arduino and the TFT display is mapped out below:

We will use two libraries from Adafruit to help us easily communicate with the LCD. The libraries include the Adafruit GFX library which can be downloaded here and the Adafruit ST7735 Library which can be downloaded here.

We will use two example sketches to demonstrate the use of the ST7735 TFT display. The first example is the lightweight TFT Display text example sketch from the Adafruit TFT examples. It can be accessed by going to examples -> TFT -> Arduino -> TFTDisplaytext. This example displays the analog value of pin A0 on the display. It is one of the easiest examples that can be used to demonstrate the ability of this display.

The second example is the graphics test example from the more capable and heavier Adafruit ST7735 Arduino library. I will explain this particular example as it features the use of the display for diverse purposes including the display of text and “animated” graphics. With the Adafruit ST7735 library installed, this example can be accessed by going to examples -> Adafruit ST7735 library -> graphics test.

The first thing, as usual, is to include the libraries to be used after which we declare the pins on the Arduino to which our LCD pins are connected to. We also make a slight change to the code setting reset pin as pin 8 and DC pin as pin 9 to match our schematics.

Next, we create an object of the library with the pins to which the LCD is connected on the Arduino as parameters. There are two options for this, feel free to choose the most preferred.

Next, we move to the void setup function where we initialize the screen and call different test functions to display certain texts or images.  These functions can be edited to display what you want based on your project needs.

Uploading the code to the Arduino board brings a flash of different shapes and text with different colors on the display. I captured one 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 as regards this project.

The 1.8" display has 128x160 color pixels. The TFT driver (ST7735) can display full 18-bit color. The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector)

In the above example, Node32-Lite and this 1.8-inch LCD.  Please refer to the tutorial here: ST7735S interfacing with ESP32 to make the connections, Arduino library installation, and modification needed for it to works on this LCD.

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 1.8″ display has 128×160 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 18-bit color (262,144 shades!). RoboticsBD

And the 1.8 Inch SPI 128×160 TFT LCD Display Module will always come with the same driver chip so there are no worries that your code will not work from one to the other. RoboticsBD

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.RoboticsBD

The TFT liquid display is provided with a semiconductor switch for each pixel, and each pixel can be directly controlled by a point pulse, so each mode is relatively independent and can be continuously controlled, which not only improves the reaction speed of the display screen, but also can accurately control.

The 7-pin display modules do not need "just" SPI, but also CS (Chip Select), D/C (Data or Command), Reset, and optionally a PWM pin for controlling the backlight. As KurtE mentioned, this should work in theory, but the problem is existing library support. The CS pins need to be separate, but all can share the D/C and Reset pins (although you cannot then reset just one display; you can only reset them all if you need to). There is always the risk that the display modules don"t like sharing their lines among so many modules -- for example, if there are too many pull-up/down resistors in the lines, or even if the modules don"t like their D/C pins toggled when their CS is not selected.

The existing ST7735 libraries I looked at do not use a canvas, but send the pixel data resulting from drawing commands via SPI. Assuming 16-bit RGB color, each 128�128 frame needs 32768 bytes; 128�160 needs 40960 bytes. With a full canvas, it would be much easier to support the eight SPI displays, because then the SPI transfers could use DMA. If the library is the only one using that SPI bus, you could avoid the CS pin restrictions by reserving the hardware CS pin (i.e., keep it unused), and let the SPI library think it is using hardware CS pins, too.

There is at least one seller on eBay with RGB TFT display modules (of various sizes) that support I2c. These have some sort of microcontroller on board, and you can set different I2C addresses for each module, so you should be able to control several of these on the same I2C bus (without the I2C multiplexer). Instead of pixel data, you send the drawing or writing commands as text to the desired module, so no library per se is needed. They also cost about three or four times as much as the above 7-pin display modules.

There are up to 1.3" single-color OLED displays using the SSD1306 controller. I have the white ones, and I like them quite a bit. Make sure you look at the four-pin ones. In the yellow/blue models, the pixels near the top are yellow, and the rest are blue, on a black background. So, each pixel is always the same color if lit: monochrome. The larger ones (0.96" and 1.3") are 128�64, the smaller (0.91") are 128�32.

Use eight identical I2C displays, and an I2C multiplexer like Adafruit sells (or a cheap eBay clone). You only need minimal changes to the Adafruit SSD1306 library, to fully support the I2C multiplexer. This is because the library only communicates with the display at init and display times. At init time, all displays need to be initialized (a new constructor function, that takes the heights of the up to eight displays into account, and drops the splash). A new variant of the .display() method takes an additional parameter, to choose the display to be updated with the current canvas; you can even update the same canvas to multiple displays. You can also add helpers so that the canvas is easy to load from a 1024- or 512-byte (128�64 or 128�32 bit) raw binary file on a microSD card (say, using Paul"s SD library), in case you want to display nice pre-drawn icons, and optionally add text/lines/bars on top. Drawing/writing text to the canvas is done using Adafruit GFX library. There is only one canvas, but you can send it to any display or displays. (You can obviously also keep the icons in Flash, but there isn"t that much room there.)
