adafruit 128x128 tft display factory

ER-TFTM1.44-2 is 128x128 pixel 1.44 inch color tft lcd display panel with ST7735S controller and breakout board,superior display quality,wide viewing angle,super 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"s 4-wire serial spi interface with pin header connection.It"s 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,medical and hand-held device.

We"ve been looking for a screen like this for a long time - it only has a 1.5" diagonal but has a high density of 220 ppi, 240x240 pixels with a wide angle display. It looks a lot like our 1.44" 128x128 screen, but it has 4x more pixels and it looks great from any angle. We have seen displays of this calibre used in smart watches and small electronic devices, but they have always been a MIPI interface. Finally, we found one that is SPI compatible and has a user-friendly display driver, so it works with all microcontrollers or microcomputers!

This pretty little display card is the best way to add a small colorful and very bright screen to any project. As the display uses 4 SPI wires to communicate and has its own addressable frame buffer per pixel, it can be used with any type of microcontroller. Even a very small one with little memory and few pins available! The 1.54" screen has 240x240 16-bit color pixels and is an IPS screen, so the color is very beautiful up to 80 degrees relative to the axis in any direction. The TFT driver (ST7789) is very similar to the popular ST7735, and our Arduino library supports it well.

Our breakout has a soldered TFT display (it uses a delicate flexible circuit connector) as well as a 3.3V regulator with very low voltage drop and a 3/5V level adapter so you can use it with 3.3V or 5V power and logic. We also had some space, so we placed a microSD card holder so you could easily load color bitmaps from a microSD card formatted FAT16/FAT32. The microSD card is not included.

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.

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.

We"ve been looking for a display like this for a long time - it"s only 1.5" diagonal but has a high density 220 ppi, 240x240 pixel display with full-angle viewing. It looks a lot like our 1.44" 128x128 display, but has 4x as many pixels and looks great at any angle. We"ve seen displays of this caliber used in smartwatches and small electronic devices but they"ve always been MIPI interface. Finally, we found one that is SPI and has a friendly display driver, so it works with any and all microcontrollers or microcomputers!

This lovely little display breakout is the best way to add a small, colorful and very 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 1.54" display has 240x240 16-bit full color pixels and is an IPS display, so the color looks great up to 80 degrees off axis in any direction. The TFT driver (ST7789) is very similar to the popular ST7735, and our Arduino library supports it well.

Our 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 .

Please note! This display is designed original for smart watches and similar, where there"s a glass over the screen. Without something gently holding the screen down, the backlight can eventually peel away from the TFT. (It"s not destructive but it"s unattractive) You can prevent this by, ideally, adding a plastic or glass cover/overlay. If using bare, try dabbing a touch of T6000 or similar craft glue on the thin side edges, or using a thin piece of tape to keep the front TFT attached to the backlight. We"re trying to find a display without this annoyance, but these displays don"t have a lot of manufacturers so pickin"s are slim!

A number of display devices like LEDs, 7-segments, character and graphic displays can be attached to microcontrollers to create an interface between the user and an electronic system for displaying data or controlling the system. Sometimes you may need to add colorful images or graphics to your project, that’s where the TFT color displays come in handy.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. In this tutorial we are going to show how to interface a 1.44″ TFT color display based on the ST7735 driver. It has 128×128 color pixels and can display full 16-bit color.

This is the type of display am using but they come with various pin configurations. However all the displays will have the major pins stated below and should be connected to the Arduino board as follows:

This TFT display uses 3.3V but comes with an on board voltage regulator therefore the VCC can be connected to the Arduino 5V. However for best practice it’s better to use the 3.3V.

Most code Libraries for this TFT ST7735 display with Arduino are programmed with the SDA and SCL pins connected to Arduino pins 11 and 13 respectively. Make sure you don’t change that order otherwise the display may not work.

There are a number of libraries that have been developed to run the TFT ST7735 color display using Arduino but I found the Adafruit-ST7735-Librarythe best to use. Make sure you have this library installed in your IDE.

tft.fillRoundRect(x,y,w,h,r,t); function draws a filled Rectangle with r radius round corners in x and y location and w width and h height and t color.

There are many other functions and commands which you can use to program the TFT color display but the above are the commonest. You will meet many more with practice.

Before we can write our personal code we need to first test the display using the already made code examples from the installed library. This is done by going to File>Examples>Adafruit ST7735 and ST7789 Library. Then you can select any of the examples and upload it to the setup to see if the display works fine.In the diagram below I have shown how to access the graphics test code.

Breakout board with ST7789 driver IC. This display does not have a CS pin, so it can’t be used with other SPI devices at the same time. To use it with the Adafruit_7735/7789 library, init using SPI_MODE3

Breakout board. Not an actual ePaper display, though it looks like one. The image fades when you remove power, but it retains for a few second. The display rate is more like an LCD.

To confirm, I had the T4 intermittently working on both the adafruit ili9341 library and the optimised ili9341_t3. I"ve been through 3 T4s and I have 5 different ILI934 displays. (all give the same results, pull ups, no pullups, removed sd circuitry, ran the T4 at 5v I"ve tried it all!)

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.
