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.

I have a sketch that displays GIFs from SD card or Flash Memory. I will have to check whether it runs on a Mega2560. I have only used it with proper 3.3V targets like Zero, Due, ESP8266, ESP32, Teensy3.2, Teensy4.0

Based on Arduino_GFX and gifdec, espgfxGIF is an Arduino sketch that plays animated GIF on TFT screen of some Arduino Dev modules, mainly esp32 and esp8266.

TFT_eSPI, which is the most common TFT graphic library, supports BMP, and MJPEG/JPEG files via drawBmp() and drawJpeg(). However, due to the way how GIF handles cmap with custom color palettes, drawGIF is not supported (as what I am aware of). Adafruit_GFX also lack support for animated GIF. Color corruption is a common issue.

Arduino_GFX is a rewritten library from Adafruit_GFX, TFT_eSPI to support various displays with various data bus interfaces. Using gifdec to fill the GIF frames into to display data bus, an animated GIF can be played on the TFT display.

9. Put your own animated GIF files on the "espgfxGIF/data" folder. Please note most esp32 DEV modules only have 1Mb of SPIFFS. Limit your total file size to 900Kb.

If you are not using m5Stack m5StickC or TTGO T-Display, please add your own configuration to the script after line 52. You need to declare your canvas and data-bus class, MOSI, SCLK, CS, DC, RST, BL pins, as well as control button pins

Arduino_DataBus *bus = new Arduino_RPiPicoSPI(27 /* DC */, 17 /* CS */, PIN_SPI0_SCK /* SCK */, PIN_SPI0_MOSI /* MOSI */, PIN_SPI0_MISO /* MISO */, spi0 /* spi */);

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:

160x128 tft display gif arduino supplier

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 content is intended to be updated from time to time, I will add more details if Arduino_GFX added more features. You can also help me enrich the content by leaving comments below.

Most hobbyist electronics market color display is SPI and most Arduino Platform support SPI. Arduino_GFX utilize Arduino native SPI class as basic interface, HWSPI, so Arduino_GFX is already virtually ready for most platform and most display.

Arduino_GFX start rewrite from Adafruit_GFX and used many features from LovyanGFX and TFT_eSPI, but the high level design is a little bit like Ucglib. Arduino_GFX decouple display driver and data interface into 2 separate class. It gives much more flexibilities, for example, ILI9341 display can use:8-bit SPI

The declaration only requires 3 lines, using create_default_Arduino_DataBus() or create_default_Arduino_GFX() still can make it simpler. This 2 functions will mention in later steps.

Arduino_GFX write as generic as possible to support multi-platform. Switching dev board no need to change any code related to GFX function. Switching display simply replacing the GFX class, e.g. switching ILI9341 display to ST7789 IPS display will be:// Arduino_GFX *gfx = new Arduino_ILI9341(bus, TFT_RST, 0 /* rotation */, false /* IPS */);

As you can see the the declaration in previous step, there are no need to pass the LED pin to both class. This is because the LED on or off is not controlled by the display driver, in most case it is direct controlled by the MCU GPIO. Sometimes it is controlled by a dedicated power control chips; Sometimes there is no LED backlight, e.g. OLED.

The most lazy way is just connect the LED pin to Vcc, but it may take a risk of burn out LED if the breakout board not have enough protection. So it is better using a GPIO:pinMode(TFT_BL, OUTPUT);

Arduino_GFX is not putting speed at the first priority, but still paid much effort to make the display look smooth. Let"s compare the speed with a most well known GFX library and 2 fastest GFX libraries.Arduino IDE: 1.8.15

Arduino_GFX write as generic as possible to support multi-platform; And use OO parent class to standardize various data bus class and display class API. These design have a little bit overhead.

Here is some design to make Arduino_GFX run fast:Tailor-made data bus classes. Arduino_GFX decouple data bus operation from display driver, it is more easy to write individual data bus class for each platform. E.g. NRFXSPI data bus class can run much faster than general HWSPI data bus class in Arduino Nano 33 BLE platform.

Stick to 16-bit color space. 24-bit color is overkilled for most MCU and also most color display support 16-bit color (except ILI948* in SPI mode). Stick to 16-bit color only can simplify the implementation, run faster and reduce library size footprint.

No read operation. Since not all display provide read back graphic memories API, Arduino_GFX skip read operations at all. It can reduce the library size footprint and sometimes reduce the operation time.

Yes, if you are using the MCU with limited program space, e.g. Arduino Nano only have 32 KB program space (exclude the size of boot loader, maximum is 30720 bytes).

In early development stage, once I added the Arcs function to PDQgraphicstest example, I found it cannot fit in Arduino Nano. A display library used up all program space means you cannot do any thing in the project. It is not acceptable, so I raise an issue in GitHub myself:

When you design your display project, there are 2 variable hardware factors to consider:Dev board. Different dev board (platform) have different GPIO pins mapping and different interface (data bus) can be used. Also driving higher resolution color display smooth requires higher processing power.

First of all, it must have common interface between the dev board and display, most likely it should be 8-bit SPI. And then you need to allocate other GPIO control pins, e.g. CS, DC, RST and LED. If you do not have preference for using which GPIOs, Arduino_GFX already defined some default for ease of use.

The official SPI for Arduino Nano 33 BLE is a little bit slow for color display, it even much slower than Arduino Nano. It is a well known issue on the web, the reason may caused by a mbedOS in the middle. When I dig into the firmware source code, I found 9 internal classes related to SPI. I selected implement 2 classes. I think NRFXSPI implementation can meet the performance of 64 MHz main frequency, mbedSPI is just a backup plan in case NRFXSPI broken something in mbedOS.

AVR family is 8-bit MCU, running in 8 or 16 MHz, maximum SPI speed is 4 MHz. Seems not fast enough for color display, as show in the first video. How about 8-bit parallel? MCU can use port operation command direct access all GPIOs under same port in 1 instruction. So AVR 8-bit parallel interface (AVRPAR8) can run much faster than SPI. However, most AVR dev board not breakout enough pins for 8-bit port operation. E.g. Arduino UNO only break out port D all 8 GPIOs but use port D require sacrifice the serial port pins.

This is a round display with 240x240 resolution. Same as ILI9341, this display is not 5V I/O tolerant so it require some resistors between GPIOs and display pins if using 5V MCU like Arduino Nano.#include

This is an IPS display with 320x480 resolution. This display only support 9-bit SPI so it is better connect with ESP32SPI.#include

This is the highest resolution display I have in hand, it is 480x800. This display support 8-bit or 16-bit parallel interface.#include

Arduino_GFX provide various canvas class, sometimes it call framebuffer, for draw buffering on complicated presentation:Canvas (16-bit color, 2 bytes for each pixel)

The display only require refresh once after canvas draw finish and call flush(). It can reduce the display flicking substantially but requires more RAM.

Then declare canvas: (240x320 resolution requires 153600 bytes RAM)Arduino_GFX *gfx = new Arduino_Canvas(240 /* width */, 320 /* height */, output_display);

Some display support 3-bit color space like ILI9488. It is hard to direct implement 3-bit color space efficiently. But it can work with a Canvas_3bit class in the middle:#include

Arduino_GFX support create default display class accordingly to selected built-in display dev device in Board selection menu. Below are recognizable dev device:Wio Terminal

Hi fantastic instructable! I have the GC9A01 running on the Arduino Nano and an SD card (working OK with the example code). It is the 240x240 px round display, but I cannot display square images larger than 165 pixels. The sketch does not validate it because the image is square not round (it gives the error "bmpMalloc failed"). How do I use the full 240x240 pixels?

If you are using 5V dev board, it depends on the display board is it have voltage conversion chip. If not, it is better add a resistor in the middle.0

The malloc error come from the BmpClass.h, Arduino Nano do not have enough RAM allocate 1 row memory i.e. 240 * 16 bit, so throw this error. Please consider use other dev broad that have more RAM or find other BMP library that no need buffer one row data(but it will draw much slower).0
