This lovely little display breakout is a great 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 0.96" display has 160x80 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. Adafruit also had a little space so they 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

Of course, Adafruit wouldn"t just leave you with a datasheet and a "good luck!" - they"ve written a full open source graphics library that can draw pixels, lines, rectangles, circles, text and bitmaps as well as example code and a wiring tutorial. The code is written for Arduino IDE but can be easily ported to your favorite microcontroller!

Say hello to the 1.14" 240x135 Color TFT Display w/ MicroSD Card Breakout– we think it"s T-F-Terrific! It"s the size of your thumbnail, with glorious 240x135 high res pixel color.

We"ve been looking for a display like this for a long time - it"s so small only 1.14" diagonal but has a high density 260 ppi, 240x135 pixel display with full-angle viewing. It looks a lot like the 0.96" 160x80 display, but has 2.5x as many pixels. We"ve seen displays of this caliber used in smartwatches and small electronic devices but they"ve always been MIPI interface. Finally, Adafruit 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 1.14" display has 240x135 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.

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. There was a little space so Adafruit placed a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card.

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.

This is a small graphics library, specifically aimed at ATtiny microcontrollers, for the variety of small colour TFT displays available at low cost from suppliers like Adafruit, AliExpress, or Banggood:

It"s an updated version of my Tiny TFT Graphics Library. This latest version of the library supports both the classic ATtiny processors, such as the ATtiny85, and the new 0-series, 1-series, and 2-series ATtiny processors, such as the ATtiny402. Like the original library it allows you to plot points, draw lines, draw filled rectangles, and plot characters and text with an optional scale factor, in 16-bit colour.

This version adds the ability to plot outline rectanges, and outline and filled circles. I"ve included demo curve-plotting and histogram-plotting programs that adjust to fit any display.

This library supports TFT displays that use an SPI interface and require four pins to drive the display. This leaves one pin free on an 8-pin chip such as the ATtiny85 or ATtiny402. If you need more pins choose a larger chip, such as the ATtiny84 or ATtiny404.

Unlike my Compact TFT Graphics Library which uses standard Arduino SPI calls, this library uses direct I/O pin manipulations. This means that you can use any assignment of pins to the four I/O lines needed by the display, and makes it about twice as fast as one using SPI calls. I"ve also added support for some additional displays, so it now supports 16 different TFT displays.

So provided you set all the pins to their disabled state at startup, the display routines can simply toggle the appropriate pins to enable or disable them.

The differences between each family of processors are handled by constants to define the pin assignments, and preprocessor macros to define the bit manipulations. If you use the circuits given below you won"t need to change anything, apart from specifying which display you"re using.

The ClearDisplay() routine has been optimised further by realising that we don"t need to keep setting the mosi bit, since to clear the display it is always zero, so the routine only needs to toggle the sck bit the appropriate number of times. I"m grateful to Thomas Scherer for suggesting this.

This library will work with displays based on the ST7735 which supports a maximum display size of 162x132, or the ST7789 and ILI9340/1 which support a maximum display size of 320x240. It includes parameters for the following colour TFT displays:

* These Adafruit displays conveniently all have the same edge-connector layout, so you can make a prototyping board or PCB that will take any of them, such as my Universal TFT Display Backpack.

Some of the AliExpress displays include a LDO 3.3V regulator, but not logic-level translation, so I recommend only interfacing them to a processor running from 3.3V.

The Adafruit displays all include an LDO 3.3V regulator and logic-level translation, so can be safely interfaced to processors powered from either 5V or 3.3V.

On the AliExpress red 160x128 display you need to connect the backlight pin to Vcc to turn it on. This doesn"t seem to be necessary with the other displays.

The library will probably support other TFT displays that use the same ST7735, ST7789, ILI9340/1 driver chips, but you may need to experiment with the parameters to get the image scaled and centered correctly.

The display needs to be connected to the microcontroller via four I/O lines: MOSI, SCK, CS, and DC. You can use any pins for these, but they should all be in the same port. You need to specify the port pin numbers of the pins you are using at the start of the Tiny TFT Graphics Library listing.

The 33kΩ pullup resistor from the display"s CS pin is optional; it is only needed on the AliExpress displays, and holds the chip select high to prevent the display from flickering while programming the ATtiny85.

The different displays are catered for by seven constants which specify the size of the display, the offsets relative to the area supported by the display driver, whether the display is inverted, the rotation value, and the order of the colours; for example:

By default the parameters give the correct orientation assuming you"re using the display with the header pins along the top, except in the case of the larger displays which have the header pins along the shorter edge, in which case the header pins are assumed to be on the left.

To check or adjust the values for each display you can run the TestChart() program, which draws a one-pixel border around the display area, and plots a red "F" to show the orientation:

The library will probably support other TFT displays that use the same driver chips, but you may need to experiment with the parameters to get the image scaled and centered correctly.

The library includes basic graphics routines for plotting points and drawing lines. These work on a conventional coordinate system with the origin at lower left. For example, on the 80x160 display:

This Bare Basic deals with connecting an Arduino with a breakout, serial SPI interfaced, 160×128 pixel color TFT display with a screen diagonal of 1.8 inch. The controller chip is a ST7735S.

The Sitronics ST7735 is a versatile display controller chip used to drive affordable, Arduino compatible TFT screens with moderate dimensions (1.8 inch display diameter; 160×128 pixels; 16-bit color). Displays with this chip can be applied as output color graphics / text display in an Arduino environment. An interesting library written by Adafruit exits that provides sufficient tools to create colorful, attractive presentation of data.

Once an Arduino has collected and manipulated data, display of the output is obvious. Reporting can be arranged via the Arduino IDE and Serial Monitor, but in this situation the Arduino must be connected to a computer while there is no way to directly produce graphical output. A separate display can be very handy for graphical data display and is especially recommended in standalone applications.

Displays for the Arduino are available in all kinds and price classes. I distinguish three groups: LCD, OLED and TFT. Well known is the monochrome LCD display with a blue or green background, usually with two lines of 16 characters or 4 lines of 20 characters, with each ‘character’ created in its own 8×5 pixel matrix. These LCD displays are good for displaying short messages or numerical values while they lack graphical capabilities and colors. Special LCD displays are the 128×64 monochrome numerical/graphical LCD display whose library offers a few primitive graphics, and the Nokia 5110 84×48 LCD display with a PCD8544 controller. LCD displays do not offer colors other than background versus character.

Figure 1: 1.8 inch 160×128 color TFT display with SPI interface on a breakout board (ST7735 compatible). Left: simple sketch showing text mode; right: graphics test mode.

A special kind of LCD is the OLED display. This family includes small, programmable graphical displays (64×32 or 128×32 pixels) in monochrome or full color.

More versatile than the LCD displays, as well as larger, are TFT displays (fig 1). These are capable of graphics and a spectrum of colors (65,536 up to 256,000 colors) to the degree that they support realistic display of color pictures. TFT displays can be bought in a dazzling array of sizes, resolution, interfaces and prices.

TFT displays for the Arduino microcontroller boards can be accessed via an 8-bit parallel data interface – fast but consuming at least 8 pins of the Arduino. An alternative is the serial SPI interface which needs only five pins.

Figure 2: Wiring of the 160×128 SPI 1.8 inch color TFT display. Note that more expensive displays have a voltage level shifter on board. This makes it possible to connect VCC with 5V instead of 3.3V as in this clone situation.

Here is a no-frills sketch that does what is needed; display some message on the display, with some color and two graphic element (one visible: the frame rectangles and one invisible: the rectangles filled with the same color as the background used to wipe out text).

ST7735 controller based TFT displays are very handy displays for use in Arduino applications. One typical application is a standalone weather station built around an Arduino platform and decorated with temperature, humidity and barometric pressure sensors. The ST7735 is less sophisticated as the bigger parallel TFT screens but displays based on this chip form a nice intermediate between the ‘big’ TFTs and the basic LCD displays.

While trying to get some 1.8" generic TFT displays to work I discovered many others had been frustrated by this problem in the past as well. It is compounded by the fact that there are at least two controllers in use (ST7735 and S6D02A1) and the only way to figure out which you have is trial-and-error, which is made difficult by the confusing way the pins are marked.

After a couple of hours of staring at a blank screen I discovered that the SPI clock signal needed to go to the pin marked SCL, not SCK as many had thought. This allowed the Adafruit Graphics Test example to run, proving my board has the S7735 controller. It also made more sense after looking at pics of a bunch of other 1.8" displays which have different PC layouts but some of which identify how one group of pins is used for the SD card (which usually have industry-standard SPI designations) and the group used for the display (which is SPI but has markings more like I2C). I have no idea why the makers of these displays used such goofy markings or why some have an extra 8 pin header, but I suspect if you wire up the pins in the sequence shown regardless of what may be printed on the PC board, it will work.

A couple of notes specific to using these displays with Teensy as I want to do: the Adafruit wiring won"t work with the Audio board attached due to a hardware conflict with a couple of pins, but if the regulator on the display is jumpered everything works fine on 3.3V, including the LED backlight.
