About: White House Maker Faire // 20 years old // U.C. Berkeley Junior in M.E.T. program. CEO of Qtechknow, maker and electronics enthusiast, I teach Arduino classes, and put making into schools! My successful Qduino…

Have you ever heard of TFT LCD screens?  They are great ways to display information from your Arduino, or display pictures.  The Arduino team just released an official TFT LCD screen with their new Robot at Maker Faire 2013.  It"s very easy to get started with!!  This tutorial will show you how to get the LCD up and running, load information from the SD card, and make a few simple projects.

The TFT LCD screen is a great way to detach your computer, and have the Arduino relay information that you need to know onto the LCD.  A great part of the LCD is that it has a built in microSD card socket.  You can store images on the microSD card socket, and even some text!

TFT LCD Screens (Thin-film-transistor liquid crystal display) are great graphical displays to display information.  They are a variant of a liquid crystal display (LCD) which uses TFT technology to improve image qualities such as addressability and contrast.  They are used often in video games, smartphones, cell phones, and sometimes even TV"s.  Now, with the technology and accessibility today, you can use one with your Arduino!

LCDs, or liquid crystal displays, are easy to use with your Arduino.  They are a very simple ways of telling the user data from the Arduino.  Standard 16x2 character LCDs are found in grocery stores, when the display tells you what you bought as the cashier scans each item, and how much it costs.

For the first example, let"s put the Instructables Logo on our TFT display!  Download the zip file below, and put it onto a microSD Card (2GB).  You will probably a microSD to SD Card adapter.  There is no special software needed, just copy and paste it onto the card.

Let"s try another example.  This time, we"ll be mimicking the Serial Monitor on our TFT LCD.  Keep the same circuit, and then upload the new code below.

This sketch will gather the reading from the ArduSensor Pot, and then relay it onto the TFT LCD screen 10 times per second.  This is a great way to display data without a computer.

Open up the CardInfo sketch from the Arduino program; File>Examples>SD>CardInfo.  Upload this to your Arduino, and then open the serial monitor in the Arduino program.

This looks like a fantastic tutorial, but could you please help: is there a cheaper alternative to the official arduino TFT screen but will still work with the tft library? Help and multiple suggestions are much appreciated!0

Without a storage medium you would need to convert the image data into an array representing each pixel and make it part of your sketch. So you would be limited by the on-board memory of the Arduino.0

I am also trying to play a video using Arduino. If I use images after split from a video as a slideshow using higher speed. will Arduino able to process it ?0

Now for landscape(rotating the screen by 1) mode the point (0,0) is located at the top left corner of screen if your arduino USB port is at the left side.maximum x coordinate is 320 and maximum y coordinate is 240( since resolution is 320*240). x value increases as we go right and y value increases as we go down. Now I have uploaded the code folder here. You see it and practice drawing lines in a new sketch and you will gradually know the orientations and you will feel easy. Then apply colors. Hex code of colors are declared at top.See them and use it. Refer to the given sketch at first.Practice is required. Refer to my code when required.

To prototype this project out for bench testing I started with the 2.8" TFT touchscreen by itself first. You just line up the pins and push it into the Arduino mega plug it into your laptop and fire up the Arduino integrated development environment software.

This is my first touch screen project so it took a bit of tinkering to figure how to calibrate the screen size, touch sensitively etc, also the TFT is not an Adafruit touchscreen meant I had to add some extra library"s such as MCUFRIEND_kbv to calibrate the screen etc.

such as:I then got the num pad display on the 2.8" TFT touchscreen to report the values via the serial monitorThen added the password element to the sketchNext was the relay sketch by itself first. This took some soldering andf wiring of the relay to the Mega. Please see the wiring diagram of the relay attached. I used pin 39 on the digital I/O on the mega to trigger the solid state relay and then turn on/off my LED ( to be replaced by the mag locks exit button wiring when fitted).

In this instructable, you"ll learn how to use theMCUfriend.com 2.4" TFT display shield for the Uno/Mega. You"ll learn how to display graphic objects and text and how to receive touches and act on the touch events. This screen is very similar to Adafruit and other TFT shields/screens. So if you"re here, stick around for the show.

When mounting the TFT shield on the Uno/Mega, BE VERY CAREFUL to make sure you"re lining up the pins correctly. I misaligned my first shield and fried it. I spent two weeks of growing frustration trying to find correct libraries before realizing that the screen was dead. BE CAREFUL!

Although this is a simplified project, it"s still rather long. I"ll provide versions of the Arduino sketches at each major stage so you can upload them if you wish.

Then we set the text size to "5". This is a relatively large basic text size. We set the x and y position for the text cursor and we set the text colour. Finally theprint("TFT") command actually draws the blue, size "5" text at the specified position.

As you increase text size, you"ll see that the characters get more and more chunky. So going above 5 is probably not helpful. At the end of this tutorial, I"ll show you how to use bitmap fonts to get nicer looking text in your apps.The tradeoff is that using bitmap font sets takes up a lot of memory in your Arduino which will limit your sketch sizes.

The downside is that loading font sets into the Arduino memory takes up significant space. In fact, it"s very easy to fill your sketch with so many fonts that it won"t load into the Arduino.

Now any print() commands will use the currently specified font. To change to a different font, you would use another tft.setFont() command with the next font you would want to use.

Upload the sketch to your Arduino and you should see the splash screen now uses the bitmap font for rendering the text on the screen. You"ll notice that the size of the sketch is significantly larger now that you"ve included a font.

The following examples use the tft.color565 method to let you specify the colour based on red, green and blue values. This is an alternative way to using the constant defined HEX colour values we used in our sketch.

I did some further work to improve the reliability of the touch sensing, adding code to map the touch points to display points. Check out my Instructableon how to do this and how to improve accuracy with 9V power sources for the Arduino/Display.

hello, when i downloaded the "tftDemo.ino" sketch, i uploaded, and it only showed qwerty on the"texting" app. i then read the code and found out that the characters for keyboard were only qwerty. how do i fix?

I found the TFT screen and Uno on Banggood.com about a month ago and over the weekend I was messing with the pair and found the tftbmp draw code in the demo.. I extended it with the ability to read any bmp file on the SD card.. so all you do is put your bitmaps on the SD and plug it in.. Having to add/edit/recompile/reload the Uno everytime is BS... Here is my code:

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

LCD displays, such as the ones used in LCDBPV2, have LCD chip to drive TFT grid pixels, in this case SSD1289 chip. This chip links each pixel with his MCU and provide Serial or parallel control to any external MCU or FPGA/CPLD.

In both modes, serial and parallel, has been programmed a new mode to improve performance:writedatasec (write sequence of data). This mode can be used because CPLD (in series comunication) and MCU (in parallel comunication) keeps data in his output buffer (to SSD1289), so is not needed to update it, saving time and MCU load. Some other news about serial mode are dual bit data and edge indications: Because CPLD design can parallelize process without losing time, so it uses two separated circuits to obtain data at the same time and later feeds register buffer. Edge indicates almost all actions of the integrated CPLD circuit to save time. In short, E.H.A. serial mode is the fastest mode possible with serial communication and allows low end MCU to drive LCD at good speed and high end LCD to save pins with speed of parallel. In fact, using writedatasec with any MCU (comparec with the same clock speed), parallel and serial mode spend the same ammount of time.

Anyway now I commented that line, beacuse I am not interested in speed right now. But now the problem seems to be the programation code. the error message is as follows: ( I am using Arduino 1.8.7)

Learn the basics of using a 2.4 inch TFT LCD shield with an Arduino. By using this color TFT LCD shield we can show characters, strings, button interfacing, bitmap images, etc. on the color TFT LCD. #Instructables #electronics #technology #arduinoproject #arduino #microcontroller #touchscreen

Quin: All of my projects with a microprocessor are Atmel-powered! Many of them are based on Arduino boards, like the FuzzBot, Gas Cap, and TFT LCD screen Instructables, and the Quasi-duino Arduino clone (also on Instructables!) uses the ATmega328 MCU with the bare minimum components needed to function as an extra small Arduino. [Since it] uses [a minimal number of] components on the breadboard, I even had to rewrite the Arduino core for it!

The Arduino board has a wide variety of compatible displays that you can use in your electronic projects. In most projects, it’s very useful to give the user some sort of feedback from the Arduino.

With the TFT display you can display colorful images or graphics. This module has a resolution of 480 x 320. This module includes the SD card socket and SPI FLASH circuit.

This is a versatile and Arduino/Seeeduino/Arduino Mega compatible resistive touch screen shield which can be used as display device, or sketch pad for user input/interface.

Compared with the previous version (2.8" TFT Touch Shield V1.0) we improved the screen driver with a professional chip (ILI9341) to provide the pin-saving SPI communication protocol without sacrificing the data transmission speed.

Function Description: The drawCircle function draws an empty circle with the center at the coordinates poX, and poY. The circle will be of radius r and the border color will be color. The color parameter is a 16-bit Red-Geen-Blue (RGB) integer, in the example code above the words YELLOW, CYAN, RED, and BLUE are defined as integers in the TFTv2.h file.

The TFT Touch Shield"s backlight is on by default since its control circuit is directly powered by the 5V pin. If, however, you wish to control the backlight"s on/off state using the Arduino Digital I/O pin 7, a simple modification will have to be made:

Now controlling the backlight"s state is as easy as controlling an LED, upload the following code to the Arduino board to see how to toggle the backlight every 500ms (1/2 second):

I still remember when I post my first Instructable post years ago, it"s a project about Arduino, I made a phone with Arduino. It"s called ArduinoPhone, even today I can get some comments from it, and I am glad to help others to make their own phone with Arduino.

Now, I will share my latest instructions, it"s a beautiful device that you can put it on the desk. It"s named Instructables Indicator. With this instructable, you can know people like your Instructable if your Instructable posts get featured.

If you like Instructables and write instruction post, you will like this idea. I will share the process to make it, as well as the code, all things are open sources.

Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with the 3D printer. Although it"s not such fine as you think, even a little bit clunky, it"s still very cool. That is the point this is a cell phone made by ourselves.

While, we can"t install Arduino Phone Apps limited by Arduino. So, if you want to play Angry Birds, then you need to do some big modifications on Arduino Phone. :)
