This lovely little display breakout is the best way to add a small, colorful and bright display on to your project. Since the display size is 1.44-inch and since TFT display 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!

Electronics has transited from a work meant for well-trained engineers to something which is dabbled into by people in other fields especially in Arts and related fields. The introduction of platforms like Arduino (which was created for reasons like this), has been one of the main facilitators of this trend which has produced diverse forms of electronics embedded art pieces, from interactive paintings to animatronic sculptures. For today’s tutorial, we will build our own work of “art” – a digital Photo Frame. Photoframes are used to display pictures or artworks and are made from wood, metal and several synthetic material. They were created to hold just one picture/artwork but with digital photo frames, you could have more than one picture stored on the photo frame,  switching between them at desired intervals.

Digital Photo frames are usually made up of four main components; a display/screen, a storage device, a microcontroller or microprocessor, and a power supply. For today’s tutorial, we will use the 1.8″ ST7735 based, color TFT as our display and the Arduino nano as the microcontroller. The 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 microcontrollers and you only need 4 IO pins.  The display module also comes with an SD card slot which we will use as the storage device for this project.

Beside just building the digital photo frame, at the end of this tutorial, you would have also learned how to use the SD card slot on the 1.8″ TFT display module for other projects.

The ST7735 1.8″ TFT display is made up of two set of header pins. The first one at the top consists of 4 pins and are used to interface the SD card slot at the back of the display.

The second set of headers below the screen represent the pins for driving the display itself. However, the SD card slot and the display, both use the SPI protocol for communications with the MCU so they will be connected to the same pins on the Arduino nano. The only difference will be the CS/SS pin as each of them will be connected to a different pin.

For this schematic, we used the Fritzing model of the ST7735 1.8″ TFT display and the arrangement of the pins is slightly different from that of our display. This model has the pins of the SD card slot and the display merged together breaking out only their CS/SS pins.

Go over the schematics one more time to be sure everything is as it should be. More on the use of the 1.8″ TFT display was covered in a previous tutorial here.

The images that will be displayed on the TFT has to be in a bitmap format, thus before the images are copied to the SD card, we need to convert them to the recognizable bitmap form. To do this, I used the free Paint.net software (for windows) but you can use any other image editing software.

Load the images into the software one by one and use the resize tool to reduce its resolution and size to that (160×128 pixels) of the 1.8″ TFT display.

The code for this project is a slightly modified version of the SPI TFT bitmap example shipped with the ST7735 library by Adafruit. Thus the code for this tutorial is heavily reliant on the Adafruit ST7735 and GFX libraries.

With this done, we declare the pins of the Arduino to which the CS pins of the SD card slot and the TFT are connected and also create an object of the Adafruit ST7735 library with the declared pins passed on as arguments.

Next is thevoid setup() function. We start by initializing serial communication which will be used to debug our code. After this, we initialize the TFT and the SDcard, setting the rotation of the TFT to landscape (represented by 1).

Next is the void loop function. Here we simply invoke the bmpDraw function for each of the images we will like to display, setting a suitable delay time between each of the pictures. The bmpDraw function makes it super easy to display images on the TFT. All we need to do is to provide the name of the .bmp file, starting coordinates and it will use that information to fetch the image from the SD card and display on the screen.

Ensure your connections are correct, then upload the code to your Arduino.  After a while, you should see the pictures being displayed like a slideshow on the TFT.

This ST7735S 1.8" TFT Display features a resolution of 128×160 and SPI (4-wire) communication. Integrated with an SD card slot, it allows you to easily read full-color bitmaps from the SD card.

The module provides users with two wiring methods: pin header wiring and GDI (General Display interface). You can directly connect the display to a FireBeetle main controller using an FPC cable. Plug and play, easy to wire. Besides, the display supports a low refresh rate and offers a good display effect and strong versatility.

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.

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!). And the LCD will always come with the same driver chip so there’s no worries that your code will not work from one to the other.

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, which allows you to use the display with virtually any microcontroller. There’s also 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.

You can download our Arduino library with examples from github. To install it, rename the downloaded and uncompressed library to ST7735 and place in the sketch folder/libraries folder. See our detailed tutorial for more info.

The display quality is very good (much better than the camera captures), although it has quite narrow viewing angle constraints, outside of 20 degrees or so it shows mostly white, without colour or generally inverted.

The display comes out of reset with vertical stripes, it"s the line shift register in the controller just repeated on every line, plus some scary regular black columns that look like dead column multiplexing drivers.

On using the red table init for the timing register, for the first time the display did something different involving all the pixels, which was very encouraging. After more prodding and poking I discovered changing it to a per-frame delay of 10 additionally made the raster come out right, showing the video data in the panel framebuffer.
