Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (5" diagonal) bright (12 white-LED backlight) and colorfu 480x272 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel attached on screen by default.
The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Due/Mega 2560).
Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!
For 5 inch screen,the high current is needed.But the current of arduino uno or arduino mega board is low, an external 5V power supply is needed. Refer to the image shows the external power supply position on shield ER-AS-RA8875.
If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

No! For about the price of a familiar 2x16 LCD, you get a high resolution TFT display. For as low as $4 (shipping included!), it"s possible to buy a small, sharp TFT screen that can be interfaced with an Arduino. Moreover, it can display not just text, but elaborate graphics. These have been manufactured in the tens of millions for cell phones and other gadgets and devices, and that is the reason they are so cheap now. This makes it feasible to reuse them to give our electronic projects colorful graphic displays.
There are quite a number of small cheap TFT displays available on eBay and elsewhere. But, how is it possible to determine which ones will work with an Arduino? And what then? Here is the procedure:ID the display. With luck, it will have identifying information printed on it. Otherwise, it may involve matching its appearance with a picture on Google images. Determine the display"s resolution and the driver chip.
Find out whether there is an Arduino driver available. Google is your friend here. Henning Karlsen"s UTFT library works with many displays. (http://www.rinkydinkelectronics.com/library.php?i...)
Download and install the driver library. On a Linux machine, as root, copy the library archive file to the /usr/share/arduino/libraries directory and untar or unzip it.
Load an example sketch into the Arduino IDE, and then upload it to the attached Arduino board with wired-up TFT display. With luck, you will see text and/or graphics.
We"ll begin with a simple one. The ILI9163 display has a resolution of 128 x 128 pixels. With 8 pins in a single row, it works fine with a standard Arduino UNO or with a Mega. The hardware hookup is simple -- only 8 connections total! The library put together by a smart fella, by the name of sumotoy, makes it possible to display text in multiple colors and to draw lines.
Note that these come in two varieties, red and black. The red ones may need a bit of tweaking to format the display correctly -- see the comments in the README.md file. The TFT_ILI9163C.h file might need to be edited.
It is 5-volt friendly, since there is a 74HC450 IC on the circuit board that functions as a level shifter. These can be obtained for just a few bucks on eBay and elsewhere, for example -- $3.56 delivered from China. It uses Henning Karlsen"s UTFT library, and it does a fine job with text and graphics. Note that due to the memory requirement of UTFT, this display will work with a standard UNO only with extensive tweaking -- it would be necessary to delete pretty much all the graphics in the sketch, and just stay with text.
This one is a 2.2" (diagonal) display with 176x220 resolution and parallel interface. It has a standard ("Intel 8080") parallel interface, and works in both 8-bit and 16-bit modes. It uses the S6D0164 driver in Henning Karlsen"s UTFT library, and because of the memory requirements of same, works only with an Arduino Mega or Due. It has an SD card slot on its back
This one is a bit of an oddball. It"s a clone of the more common HY-TFT240, and it has two rows of pins, set at right angles to one another. To enable the display in 8-bit mode, only the row of pins along the narrow edge is used. The other row is for the SD card socket on the back, and for 16-bit mode. To interface with an Arduino ( Mega or Due), it uses Henning Karlsen"s UTFT library, and the driver is ILI9325C. Its resolution is 320x240 (hires!) and it incorporates both a touch screen and an SD card slot.
Having determined that a particular TFT display will work with the Arduino, it"s time to think about a more permanent solution -- constructing hard-wired and soldered plug-in boards. To make things easier, start with a blank protoshield as a base, and add sockets for the TFT displays to plug into. Each socket row will have a corresponding row next to it, with each individual hole "twinned" to the adjacent hole in the adjoining row by solder bridges, making them accessible to jumpers to connect to appropriate Arduino pins. An alternative is hard-wiring the socket pins to the Arduino pins, which is neater but limits the versatility of the board.
In step 5, you mention that the TFT01 display can"t be used with the UTFT library on an Arduino Uno because of its memory requirements. It can - all you have to do is edit memorysaver.h and disable any display models you"re not using.
I think you should add a disclaimer that the code might make the Arduino Uno unprogrammable afterward (due to use up the two 0 and 1 pin) and link to how to fix it: https://stackoverflow.com/questions/5290428/how-to-reset-an-arduino-board/8453576?sfb=2#84535760
Tho I realize this is quickly becoming legacy hardware, these 8,16 bit parallel spi with 4 wire controller 3.2in Taft touch display 240x380. It has become very inexpensive with ally of back stock world wide so incorporating them into any project is easier then ever. Sorry to my question. I’m having difficulty finding wiring solution for this lcd. It is a sd1289 3.3 and 5v ,40 pin parallel 8,16 bit. I do not want to use a extra shield,hat or cape or adapter. But there’s a lot of conflicting info about required lvl shifters for this model any help or links to info would be great .. thank you. I hope I gave enough information to understand what I’m adoing
#1 you need a data sheet for the display and pinout and the i/o board attached to the cable.Than before you buy check for a driver for this chip Raydium/RM69071.if no driver lib are you able to write one and do you have the necessary tools to work on this scale to wire it up ..if you answer no than search for an arduino ready product.WCH0
hooking up and adding a lib is no piece of cake insure the screen you buy is arduino ready and sold by a reputable shop with step by step directions...WCH0
I"m sorry that I can"t help you with this. You"ll have to do your own research. See if you can identify the chipset and find out if there"s an Arduino driver for it.0
New functions have been added to draw smooth (antialiased) arcs, circles, and rounded rectangle outlines. New sketches are provided in the "Smooth Graphics" examples folder. Arcs can be drawn with or without anti-aliasing (which will then render faster). The arc ends can be straight or rounded. The arc drawing algorithm uses an optimised fixed point sqrt() function to improve performance on processors that do not have a hardware Floating Point Unit (e.g. RP2040). Here are two demo images, on the left smooth (anti-aliased) arcs with rounded ends, the image to the right is the same resolution (grabbed from the same 240x240 TFT) with the smoothing diasbled (no anti-aliasing):
An excellent new compatible library is available which can render TrueType fonts on a TFT screen (or into a sprite). This has been developed by takkaO, I have created a branch with some bug fixes here. The library provides access to compact font files, with fully scaleable anti-aliased glyphs. Left, middle and right justified text can also be printed to the screen. I have added TFT_eSPI specific examples to the OpenFontRender library and tested on RP2040 and ESP32 processors, the ESP8266 does not have sufficient RAM due to the glyph render complexity. Here is a demo screen where a single 12kbyte font file binary was used to render fully anti-aliased glyphs of gradually increasing size on a 320x480 TFT screen:
Smooth fonts can now be rendered direct to the TFT with very little flicker for quickly changing values. This is achieved by a line-by-line and block-by-block update of the glyph area without drawing pixels twice. This is a "breaking" change for some sketches because a new true/false parameter is needed to render the background. The default is false if the parameter is missing, Examples:
Users of PowerPoint experienced with running macros may be interested in the pptm sketch generator here, this converts graphics and tables drawn in PowerPoint slides into an Arduino sketch that renders the graphics on a 480x320 TFT. This is based on VB macros created by Kris Kasprzak here.
A feature rich Arduino IDE compatible graphics and fonts library for 32 bit processors. The library is targeted at 32 bit processors, it has been performance optimised for RP2040, STM32, ESP8266 and ESP32 types, other 32 bit processors may be used but will use the slower generic Arduino interface calls. The library can be loaded using the Arduino IDE"s Library Manager. Direct Memory Access (DMA) can be used with the ESP32, RP2040 and STM32 processors with SPI interface displays to improve rendering performance. DMA with a parallel interface (8 and 16 bit) is only supported with the RP2040.
The screen controller, interface pins and library configuration settings must be defined inside the library. They can NOT be defined in the Arduino sketch. See the User_Setup_Select.h file for details. This approach has significant advantages, it keeps the examples clean from long configuration options and once the setup is defined any example can be run without modification. PlatformIO users can define these settings on a per project basis within a platformio.ini file, see Docs folder in library.
Lots of example sketches are provided which demonstrate using the functions in the library. Due to the popularity of the library there are lots of online tutorials for TFT_eSPI that have been created by enthusiastic users.
For other (generic) processors only SPI interface displays are supported and the slower Arduino SPI library functions are used by the library. Higher clock speed processors such as used for the Teensy 3.x and 4.x boards will still provide a very good performance with the generic Arduino SPI functions.
Due to lack of GPIO pins the 8 bit parallel interface is NOT supported on the ESP8266. 8 bit parallel interface TFTs (e.g. UNO format mcufriend shields) can used with the STM32 Nucleo 64/144 range or the UNO format ESP32 (see below for ESP32).
Support for the XPT2046 touch screen controller is built into the library and can be used with SPI interface displays. Third party touch support libraries are also available when using a display parallel interface.
The library supports some TFT displays designed for the Raspberry Pi (RPi) that are based on a ILI9486 or ST7796 driver chip with a 480 x 320 pixel screen. The ILI9486 RPi display must be of the Waveshare design and use a 16 bit serial interface based on the 74HC04, 74HC4040 and 2 x 74HC4094 logic chips. Note that due to design variations between these displays not all RPi displays will work with this library, so purchasing a RPi display of these types solely for use with this library is NOT recommended.
A "good" RPi display is the MHS-4.0 inch Display-B type ST7796 which provides good performance. This has a dedicated controller and can be clocked at up to 80MHz with the ESP32 (125MHz with overclocked RP2040, 55MHz with STM32 and 40MHz with ESP8266). The MHS-3.5 inch RPi ILI9486 based display is also supported, however the MHS ILI9341 based display of the same type does NOT work with this library.
Some displays permit the internal TFT screen RAM to be read, a few of the examples use this feature. The TFT_Screen_Capture example allows full screens to be captured and sent to a PC, this is handy to create program documentation.
The library supports Waveshare 2 and 3 colour ePaper displays using full frame buffers. This addition is relatively immature and thus only one example has been provided.
The library includes a "Sprite" class, this enables flicker free updates of complex graphics. Direct writes to the TFT with graphics functions are still available, so existing sketches do not need to be changed.
The "Animated_dial" example shows how dials can be created using a rotated Sprite for the needle. To run this example the TFT interface must support reading from the screen RAM (not all do). The dial rim and scale is a jpeg image, created using a paint program.
The XPT2046 touch screen controller is supported for SPI based displays only. The SPI bus for the touch controller is shared with the TFT and only an additional chip select line is needed. This support will eventually be deprecated when a suitable touch screen library is available.
The library supports SPI overlap on the ESP8266 so the TFT screen can share MOSI, MISO and SCLK pins with the program FLASH, this frees up GPIO pins for other uses. Only one SPI device can be connected to the FLASH pins and the chips select for the TFT must be on pin D3 (GPIO0).
The library contains proportional fonts, different sizes can be enabled/disabled at compile time to optimise the use of FLASH memory. Anti-aliased (smooth) font files in vlw format stored in SPIFFS are supported. Any 16 bit Unicode character can be included and rendered, this means many language specific characters can be rendered to the screen.
The library is based on the Adafruit GFX and Adafruit driver libraries and the aim is to retain compatibility. Significant additions have been made to the library to boost the speed for the different processors (it is typically 3 to 10 times faster) and to add new features. The new graphics functions include different size proportional fonts and formatting features. There are lots of example sketches to demonstrate the different features and included functions.
Configuration of the library font selections, pins used to interface with the TFT and other features is made by editing the User_Setup.h file in the library folder, or by selecting your own configuration in the "User_Setup_Selet,h" file. Fonts and features can easily be enabled/disabled by commenting out lines.
Anti-aliased (smooth) font files in "vlw" format are generated by the free Processing IDE using a sketch included in the library Tools folder. This sketch with the Processing IDE can be used to generate font files from your computer"s font set or any TrueType (.ttf) font, the font file can include any combination of 16 bit Unicode characters. This means Greek, Japanese and any other UCS-2 glyphs can be used. Character arrays and Strings in UTF-8 format are supported.
It would be possible to compress the vlw font files but the rendering performance to a TFT is still good when storing the font file(s) in SPIFFS, LittleFS or FLASH arrays.
Anti-aliased fonts can also be drawn over a gradient background with a callback to fetch the background colour of each pixel. This pixel colour can be set by the gradient algorithm or by reading back the TFT screen memory (if reading the display is supported).
Unfortunately the typical UNO/mcufriend TFT display board maps LCD_RD, LCD_CS and LCD_RST signals to the ESP32 analogue pins 35, 34 and 36 which are input only. To solve this I linked in the 3 spare pins IO15, IO33 and IO32 by adding wires to the bottom of the board as follows:
If the display board is fitted with a resistance based touch screen then this can be used by performing the modifications described here and the fork of the Adafruit library:
If you load a new copy of TFT_eSPI then it will overwrite your setups if they are kept within the TFT_eSPI folder. One way around this is to create a new folder in your Arduino library folder called "TFT_eSPI_Setups". You then place your custom setup.h files in there. After an upgrade simply edit the User_Setup_Select.h file to point to your custom setup file e.g.:
You must make sure only one setup file is called. In the custom setup file I add the file path as a commented out first line that can be cut and pasted back into the upgraded User_Setup_Select.h file. The ../ at the start of the path means go up one directory level. Clearly you could use different file paths or directory names as long as it does not clash with another library or folder name.
In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.
As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.
Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.
I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.
After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.
So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.
In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work you can check my particular tutorial. Here you can download that file:

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 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.
On the classic ATtiny processors, such as the ATtiny85, the library uses the feature that you can toggle one or more bits in a port by writing to the PINB register; for example, to enable or disable the chip-select signal:
The library occupies less than 4K bytes, including the character set and demo programs, and so will fit on microcontrollers with 4K flash such as the ATtiny45 and ATtiny402.
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.
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 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:
Adafruit_ST7735 is the library we need to pair with the graphics library for hardware specific functions of the ST7735 TFT Display/SD-Card controller.
In the file dialog select the downloaded ZIP file and your library will be installed automatically. This will automatically install the library for you (requires Arduino 1.0.5 or newer). Restarting your Arduino software is recommended as it will make the examples visible in the examples menu.
The easiest way to remedy this is by extracting the GitHub ZIP file. Place the files in a directory with the proper library name (Adafruit_GFX, Adafruit_ST7735 or SD) and zip the folder (Adafruit_GFX, Adafruit_ST7735.zip, SD.zip). Now the Arduino software can read and install the library automatically for you.
Basically, besides the obvious backlight, we tell the controller first what we are talking to with the CS pins. CS(TFT) selects data to be for the Display, and CS(SD) to set data for the SD-Card. Data is written to the selected device through SDA (display) or MOSI (SD-Card). Data is read from the SD-Card through MISO.
As mentioned before, the display has a SLOW and a FAST mode, each serving it’s own purpose. Do some experiments with both speeds to determine which one works for your application. Of course, the need of particular Arduino pins plays a role in this decision as well …
Low Speed display is about 1/5 of the speed of High Speed display, which makes it only suitable for particular purposes, but at least the SPI pins of the Arduino are available.
After connecting the display in Low Speed configuration, you can load the first example from the Arduino Software (“File” “Example” “Adafruit_ST7735” – recommend starting with the “graphictest“).
You can name your BMP file “parrot.bmp” or modify the Sketch to have the proper filename (in “spitftbitmap” line 70, and in “soft_spitftbitmap” line 74).
#define SD_CS 4 // Chip select line for SD card#define TFT_CS 10 // Chip select line for TFT display#define TFT_DC 9 // Data/command line for TFT#define TFT_RST 8 // Reset line for TFT (or connect to +5V)
#define SD_CS 4 // Chip select line for SD card#define TFT_CS 10 // Chip select line for TFT display#define TFT_DC 9 // Data/command line for TFT#define TFT_RST 8 // Reset line for TFT (or connect to +5V)
As you have seen before the Adafruit_GFX library (supported by the Adafruit_ST7735 library) makes this easy for us – More information can be found at the GFX Reference page.
To use this in your Arduino Sketch: The first 2 characters represent RED, the second set of two characters is for GREEN and the last 2 characters represent BLUE. Add ‘0x’ in front of each of these hex values when using them (‘0x’ designates a hexadecimal value).
Based on these functions, I did create a little demo to show what these functions do. Either download the file or just copy the code and paste it into an empty Arduino Sketch.
tft.print("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. ");
Add a LCD screen to your next Arduino project. The Arduino Graphic LCD (GLCD) screen is a backlit TFT LCD screen with headers. You can draw text, images, and shapes to the screen with the GLCD library. There is an onboard micro-SD card slot on the back of the screen that can, among other things, store bitmap images for the screen to display.
The screen"s headers are designed to fit into the socket on the front of the Arduino Esplora, but it is compatible with any AVR-based Arduino (Uno, Leonardo, etc. Datasheet You can use this module with Arduino Esplora. To connect the screen to other Arduino boards, read the tutorial on this link.
NOTE: If you expensive 4-5 thick white/black line when using the LCD screen, it is due to a compatibility issue. Arduino changed one of the controllers on the LCD board recently (in all products that use the LCD), and this was incompatible with their LCD library. A fixed TFT Library is included in the nightly build of the 1.5.4 IDE. You can download this here: http://arduino.cc/en/Main/Software#toc4
