This module is a 3.5-inch TFT LCD module with “320X480” resolution and 65K color display. It is suitable for Arduino Uno and Mega2560 development boards, and also supports SD card expansion function. It uses 8-bit parallel port communication, and the driver IC is ILI9486.

The 3.5-inch display is a ready-made shield for Arduino Uno, which can also be placed on the Arduino Mega. The pins of this shield are designed to be easily installed on the Arduino. The bad point about these modules is that they use all Arduino Uno pins.

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.

For prototyping and testing:A solderless breadboard male-to-male jumpers male-to-female jumpers 22 gauge insulated hookup wire, solid Graph paper, for planning and sketching wiring diagrams and layouts

A couple of sets (4 each) of decent rechargeable NIMH AA batteries. Note: Beware of cheap ripoff batteries from Hong Kong. These typically take only a 200 mA charge, and even an "intelligent" charger will not refresh them. Purple, blue, and green ones are suspect -- see picture and ... Link #1Link #2

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.

on the far side of the display. It has 220x176 resolution (hires!) and will accept either 3.3 or 5 volts. It will work hooked up to an Uno, and with a few pin changes, also with a Mega. The 11-pin row is for activating the display itself, and the 5-pin row for the SD socket on its back.

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.

The key to an effective DIY shield is a neat and logical layout. Sketching the prospective shield on quadrille (graph) paper may be helpful. A multitester or continuity tester might be useful for detecting wiring and soldering errors.

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

Thanks for the wealth of knowledge! It is amazing at what is possible with items the average person can easily acquire. I hope to put some of your tips to use this winter as I would like to build sensors and other items for home automation and monitoring. Being able to have small displays around the house in addition to gathering and controlling things remotely will help the family see room conditions without going to the computer. The idea of a touchscreen control for cheap is mind blowing.

In this tutorial, you will learn how to use and set up 2.4″ Touch LCD Shield for Arduino. First, you’ll see some general information about this shield. And after learning how to set the shield up, you’ll see 3 practical projects.

The role of screens in electronic projects is very important. Screens can be of very simple types such as 7 Segment or character LCDs or more advanced models like OLEDs and TFT LCDs.

One of the most important features of this LCD is including a touch panel. If you are about to use the LCD, you need to know the coordinates of the point you touch. To do so, you should upload the following code on your Arduino board and open the serial monitor. Then touch your desired location and write the coordinates displayed on the serial monitor. You can use this coordination in any other project.

To display pictures on this LCD you should save the picture in 24bit BMP colored format and size of 240*320. Then move them to SD card and put the SD card in the LCD shield. we use the following function to display pictures. This function has 3 arguments; the first one stands for the pictures name, and the second and third arguments are for length and width coordinates of the top left corner of the picture.

If you want to display pictures without using an SD card, you can convert it to code and then display it. You can display even several photos sequentially without delay to create an animation. (Check this) But be aware that in this case, Arduino UNO may not be suitable (because of low processor speed). We recommend using the Arduino Mega or Arduino DUE.

This TFT LCD display can display colour graphics and is a touch sensitive screen. It has an SD card slot too for storing images.This display board can be inserted directly on to the Arduino pins, without using any wires. That’s why it is called a shield.

Wiring is so easy – just plug the display shield on to the Arduino pins. While plugging it in, make sure that the 5V of the LCD goes to the 5V of the Arduino UNO board and also remember to stick a piece of insulation tape on the Arduino’s USB port to avoid short circuits.

Adafruit_GFX library – It’s the core graphics library. Go to Sketch -> Include Library -> Library Manager menu in the Arduino IDE and search for Adafruit_GFX. It can be installed from the library manager or can be downloaded from this link : https://github.com/adafruit/Adafruit-GFX-Library/archive/master.zip

Adafruit_TFTLCD library – It’s the LCD’s hardware specific library. The original version of the Adafruit_TFTLCD library did not work for me. So, I used a modified version of it. Someone has modified the library for various chipsets and I found it from the arduino forum for my display board. The modified version can be found here : https://forum.arduino.cc/index.php?action=dlattach;topic=288475.0;attach=107569. Download it to the libraries folder of the Arduino IDE.

It’s better to know the TFT display’s driver ID. To find that out, I wrote a program (available at the end of this note). The program will print the LCD’s driver ID into the serial monitor and will also display colours on the LCD screen.  After uploading the program, just make sure that the  serial monitor is open and the baud rate is set to 9600.

Adafruit_TFTLCD has some examples along with the library. They can be compiled and uploaded to try the display. Examples like tftpaint marks out the point were we touch.

As I can read your link, the shield is using D2-D8 and A0-A3, leaving some pins unused. So some Arduino pins are still free to use, just the shield is in the way to get connected there.

brutally solder some wires to the shield unused pins from front side and use that wires to connect where you want (sensors, breadboard, universal PCB, ...)

create intermediate shield (there are many, which allow you connect to arduinou on bottom and stack antother shield on top, draw your wires from there (and maybe even put some circuities on the middle shield, if you want

(something like this https://www.aliexpress.com/item/UNO-Prototype-DIY-shield-kit-for-Arduino-UNO-Universal-Extend-Board-UM-UNO/32555004112.html or any "arduino universal shield"

use pins D10-D13 as they are connected also to ISP header https://www.arduino.cc/en/Tutorial/ArduinoISP and could be connected from there. As they are part of SPI interface

It is possible to connect more arduinos, there are so much different ways, that it is hard to write here all - choose one, that would suit you best. (anyway you would need some access to some pins anyway )

This module is designed to plug directly into Arduino UNO R3 (or its clone) boards. It is compatible with CH340 and Atmega16u2 version boards, as well as Mega 2560. This LCD shield may also work with other boards, but the compatibility can"t be guaranteed.

Note: The following picture is the connection diagram of the 2.8-inch TFT screen and Arduino uno, but this product is connected in exactly the same way.

If the Arduino board has an ICSP interface, set the SPI Config switch on the display module to the ICSP direction (by default) (the company"s Arduino UNO motherboard has an ICSP interface, just plug it in directly.).

This product uses the same LCD control chip and touch panel control chip as the 3.5-inch TFT screen of the same series of our company, so the code is completely compatible. The following takes 3.5-inch TFT as an example to introduce.

LCD_Show can display colorful patterns with different shapes and times. LCD_ShowBMP is for displaying the picture in BMP, and LCD_Touch is for using the touching function.

The display controller used in this product is ILI9486, and we need to initialize the controller through the SPI communication protocol, and the initialization functions are written in LCD_Driver.cpp.

The function functions related to the screen display are written in LCD_GUI.cpp. The function of each function and the parameters passed are explained in the source code. You can call it directly when you need to use it.

Before using LCD_ShowBMP to display pictures, first copy the pictures in the PIC folder in the data to the root directory of the SD card (you should understand that in the root directory, that is to save the pictures directly to the SD card, do not put them in any subfolders folder.).

Here is an explanation. This demo shows that the BMP picture first reads the picture data in the BMP format in the SD card through the SPI protocol, and then displays the data as an image.

These functions are all written in LCD_Bmp.cpp. In fact, the image data in BMP format with a specific file name is read from the SD card, and then the display function written by us is called to re-express the data as an image.

No matter which platform this method is on, the principle is similar. Interested friends can check the relevant information and study the relevant code carefully.

After running this demo, there are five colors on the right side of the screen. Black is the default color in the system, and you can touch it to choose the brush color. Click AD button, and click the red "+" to calibrate the screen with the prompts. Click the right corner "CLEAR" to clear the drawing board.

If you need characters in different sizes and fonts, you can generate the font library you want according to the font extraction software provided in the Resource.

In fact, you can also use Image2Lcd image modulo software to convert images of different sizes and formats into array data, and then use the functions we wrote to display them.

The data sheets of all control chips are given in the information for your reference. If you want to know more about why the underlying functions are written like this, go to the data sheets and look at them!

The demo has been tested on XNUCLEO-F103RB, just insert XNUCLEO-F103RB as shown below. The model of XNUCLEO-F103RB is STM32F103RBT6. If you need to port the program, please connect it according to the actual pin and the schematic diagram.

Note: The following picture is the connection diagram of the 2.8-inch TFT screen and XNUCLEO-F103RB, but this product is connected in exactly the same way.

The demos are developed based on the HAL library. Download the program, find the STM32 program file directory, and open STM32\XNUCLEO-F103RB\lcd4in-demo\MDK-ARM\ lcd4in-demo.uvprojx.

This product uses the same LCD control chip and touch panel control chip as the 3.5-inch TFT screen of the same series of our company, so the code is completely compatible. The following takes 3.5-inch TFT as an example to introduce.

After running the demo, it displays some characters and patterns at first, then displays four pictures, and finally displays the touch sketchpad function. Actually, three projects in the Arduino platform code are integrated in the main function, we place the three main functions in sequence and place TP_DrawBoard(); in an infinite loop to achieve the above functions.

Before using LCD_ShowBMP to display pictures, copy the pictures in the PIC folder in the data to the root directory of the SD card, and then insert the SD card into the SD card slot on the back of the screen to start the download program verification.

It should be noted here that the SD card should be in the FAT format, and the picture should be 480*320 pixels with 24-bit color depth and BMP format.

If you need characters of different sizes and fonts, you can generate the font library you want according to the font extraction software provided in the data.

In fact, you can also use Image2Lcd image modulo software to convert images of different sizes and formats into array data, and then use the functions we wrote to display them.

The data sheets of all control chips are given in the information for your reference. If you want to know more about why the underlying functions are written like this, go to the data sheets and look at them!

Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today’s tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino.

This 3.5″ color TFT display as mentioned above, is based on the ILI9481 TFT display driver. The module offers a resolution of 480×320 pixels and comes with an SD card slot through which an SD card loaded with graphics and UI can be attached to the display. The module is also pre-soldered with pins for easy mount (like a shield) on either of the Arduino Mega and Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.

The module is compatible with either of the Arduino Uno or the Arduino Mega, so feel free to choose between them or test with both. As usual, these components can be bought via the links attached to them.

One of the good things about this module is the ease with which it can be connected to either of the Arduino Mega or Uno. For this tutorial, we will use the Arduino Uno, since the module comes as a shield with pins soldered to match the Uno’s pinout. All we need to do is snap it onto the top of the Arduino Uno as shown in the image below, thus no wiring required.

This ease of using the module mentioned above is, however, one of the few downsides of the display. If we do not use the attached SD card slot, we will be left with 6 digital and one analog pin as the module use the majority of the Arduino pins. When we use the SD card part of the display, we will be left with just 2 digital and one analog pin which at times limits the kind of project in which we can use this display. This is one of the reasons while the compatibility of this display with the Arduino Mega is such a good news, as the “Mega” offers more digital and analog pins to work with, so when you need extra pins, and size is not an issue, use the Mega.

To easily write code to use this display, we will use the GFX and TFT LCD libraries from “Adafruit” which can be downloaded here. With the library installed we can easily navigate through the examples that come with it and upload them to our setup to see the display in action. By studying these examples, one could easily learn how to use this display. However, I have compiled some of the most important functions for the display of text and graphics into an Arduino sketch for the sake of this tutorial. The complete sketch is attached in a zip file under the download section of this tutorial.

As usual, we will do a quick run through of the code and we start by including the libraries which we will use for the project, in this case, the Adafruit GFX and TFT LCD libraries.

With this done, the Void Setup() function is next. We start the function by issuing atft.reset() command to reset the LCD to default configurations. Next, we specify the type of the LCD we are using via the LCD.begin function and set the rotation of the TFT as desired. We proceed to fill the screen with different colors and display different kind of text using diverse color (via the tft.SetTextColor() function) and font size (via the tft.setTextSize() function).

The Adafruit library helps reduce the amount of work one needs to do while developing the code for this display, leaving the quality of the user interface to the limitations of the creativity and imagination of the person writing the code.

In this tutorial, you will learn how to use and set up 2.4″ Touch LCD Shield for Arduino. First, you’ll see some general information about this shield. And after learning how to set the shield up, you’ll see 3 practical projects.

To display pictures on this LCD you should save the picture in 24bit BMP colored format and size of 240*320. Then move them to SD card and put the SD card in the LCD shield. we use the following function to display pictures. This function has 3 arguments; the first one stands for the pictures name, and the second and third arguments are for length and width coordinates of the top left corner of the picture.bmpdraw(“filename.bmp”,x,y);

Final NotesIf you want to display pictures without using an SD card, you can convert it to code and then display it. You can display even several photos sequentially without delay to create an animation. (Check this)But be aware that in this case, Arduino UNO may not be suitable (because of low processor speed). We recommend using the Arduino Mega or Arduino DUE.
