160x128 tft display st7735 pricelist

We just love this little 1.8" TFT display, with true TFT color (up to 18-bits per pixel!), fine 160x128 resolution, two white LED backlight that runs on 3.3V and a very easy SPI interface that requires only 4 or 5 digital pins to send pixels to the display.

Please note! This is just the raw display, not attached to a PCB or for use with a breadboard. If you want to use this out of the box with no surface mount soldering, check out assembled 1.8" TFT breakout board. This display is for experts who are comfortable soldering a surface mount display using fine pitch soldering techniques! This display also is for 3.3V use only, so be sure to use a level shifter if you"re going to use it with 5.0V microcontrollers.

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.

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.

testdrawtext("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Curabitur adipiscing ante sed nibh tincidunt feugiat. Maecenas enim massa, fringilla sed malesuada et, malesuada sit amet turpis. Sed porttitor neque ut ante pretium vitae malesuada nunc bibendum. Nullam aliquet ultrices massa eu hendrerit. Ut sed nisi lorem. In vestibulum purus a tortor imperdiet posuere. ", ST7735_WHITE);

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.

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

It works with TFT displays available from AliExpress, and I"ve included four examples showing how you can do things that wouldn"t be possible without the ability to read from the display.

You can use an exclusive-OR drawing mode that changes the state of pixels reversibly. Drawing the same thing a second time restores the display to its previous state. This is especially important for dynamic data plotting.

To implement these applications without the ability to read pixels from the display would require you to keep a mirror of the display in RAM, and update the mirror every time you draw to the actual display. This would slow down graphics and require a lot of memory: for example, to mirror a 320x240 colour display would require 153.6Kbytes of RAM. To put this in context, the ATtiny414 used to run these examples only has 256 bytes of RAM.

Unfortunately this feature does not work with Adafruit displays, which is why I didn"t include it in my original Tiny TFT Graphics Library 2. It is, however, compatible with all displays based on the ST7735 and ST7789 driver chips available from vendors such as AliExpress and Banggood. Here"s a list of displays I"ve tested:

Adafruit have a range of great TFT displays, in a wide selection of sizes and resolutions, but unfortunately they are not compatible with this library. The reason is that their displays all include a unidirectional on-board logic-level converter to allow them to be used with either 3.3V or 5V, but this has the downside of preventing them from being able to read back from the display memory.

The solution would be to replace the unidirectional logic-level converter on the MOSI connection to the display driver with a bidirectional one, which would require one N-MOSFET and two resistors. I originally planned to include details of how to modify an Adafruit display to implement this, but I"ve decided against this because the displays are fragile, and the risk of ending up with a non-functional display is too great.

This first uses the display commands CASET and RASET to set the column range and row range to the current point. It then gives the RAM read command, RAMRD.

The sequence to shift the 21 bits into the variable pixel needs to be slightly different depending on whether the display uses the ST7735 or ST7789 driver chip. The two if statements determine this from the width of the display, and toggle the sck pin either before or after reading the mosi pin, as appropriate. It took a bit of experimentation to figure this out.

These examples included with the library demonstrate applications of reading back from the display memory. For convenience I"ve used my Universal TFT Display Backpack to run these examples, but that"s not necessary.

This simple demo takes a triangular section of an existing image on the screen, and reflects it through horizontal, vertical, and diagonal lines to create a symmetrical image, like a kaleidoscope. It works best on square displays; here it is on a 240x240 1.54" display:

To run it first draw an image, and then run Kaleidoscope(). For this example the initial image is the Waterfall() demo, used for the title image in the article Tiny TFT Graphics Library 2:

The stopwatch takes advantage of exclusive-OR plotting to draw and undraw the hand when it moves without corrupting the clock face. It is designed for a 128x128 display:

Anything drawn in red on the display is treated as a barrier, and the ball will bounce off it. Any other colours, such as the white text, are ignored and can be used to create an interesting background.

The final demo draws the BarChart() demo, and it then calls BMPSave() to save it to a BMP-format image file on an SD card. Here"s the BarChart() demo running on a 320x170 display:

Here is the version of the Tiny TFT Graphics Library with the extensions for reading from the display, and the demos described above (excluding BMPSave()): Tiny TFT Graphics Library with Read.

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 below 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.

You don"t dismantle anything. Just look at the pcb side of your display. There will be some visible chips and some printed information e.g. model number.
