arduino tft display programming manufacturer

In electronics world today, Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits.

The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. It aims to provide a low-cost and easy way for hobbyist and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.

In order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.

Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

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:

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.

In this article, you will learn how to use TFT LCDs by Arduino boards. From basic commands to professional designs and technics are all explained here.

In electronic’s projects, creating an interface between user and system is very important. This interface could be created by displaying useful data, a menu, and ease of access. A beautiful design is also very important.

There are several components to achieve this. LEDs,  7-segments, Character and Graphic displays, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, type of user interaction, and processor capacity.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.

In Arduino-based projects, the processor frequency is low. So it is not possible to display complex, high definition images and high-speed motions. Therefore, full-color TFT LCDs can only be used to display simple data and commands.

In this article, we have used libraries and advanced technics to display data, charts, menu, etc. with a professional design. This can move your project presentation to a higher level.

Size of displays affects your project parameters. Bigger Display is not always better. if you want to display high-resolution images and signs, you should choose a big size display with higher resolution. But it decreases the speed of your processing, needs more space and also needs more current to run.

After choosing the right display, It’s time to choose the right controller. If you want to display characters, tests, numbers and static images and the speed of display is not important, the Atmega328 Arduino boards (such as Arduino UNO) are a proper choice. If the size of your code is big, The UNO board may not be enough. You can use Arduino Mega2560 instead. And if you want to show high resolution images and motions with high speed, you should use the ARM core Arduino boards such as Arduino DUE.

In electronics/computer hardware a display driver is usually a semiconductor integrated circuit (but may alternatively comprise a state machine made of discrete logic and other components) which provides an interface function between a microprocessor, microcontroller, ASIC or general-purpose peripheral interface and a particular type of display device, e.g. LCD, LED, OLED, ePaper, CRT, Vacuum fluorescent or Nixie.

The display driver will typically accept commands and data using an industry-standard general-purpose serial or parallel interface, such as TTL, CMOS, RS232, SPI, I2C, etc. and generate signals with suitable voltage, current, timing and demultiplexing to make the display show the desired text or image.

The LCDs manufacturers use different drivers in their products. Some of them are more popular and some of them are very unknown. To run your display easily, you should use Arduino LCDs libraries and add them to your code. Otherwise running the display may be very difficult. There are many free libraries you can find on the internet but the important point about the libraries is their compatibility with the LCD’s driver. The driver of your LCD must be known by your library. In this article, we use the Adafruit GFX library and MCUFRIEND KBV library and example codes. You can download them from the following links.

You must add the library and then upload the code. If it is the first time you run an Arduino board, don’t worry. Just follow these steps:Go to www.arduino.cc/en/Main/Software and download the software of your OS. Install the IDE software as instructed.

By these two functions, You can find out the resolution of the display. Just add them to the code and put the outputs in a uint16_t variable. Then read it from the Serial port by Serial.println(); . First add Serial.begin(9600); in setup().

First you should convert your image to hex code. Download the software from the following link. if you don’t want to change the settings of the software, you must invert the color of the image and make the image horizontally mirrored and rotate it 90 degrees counterclockwise. Now add it to the software and convert it. Open the exported file and copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are sizes of image. you can change the color of the image in the last input.

Upload your image and download the converted file that the UTFT libraries can process. Now copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are size of the image.

In this template, We converted a .jpg image to .c file and added to the code, wrote a string and used the fade code to display. Then we used scroll code to move the screen left. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We used sin(); and cos(); functions to draw Arcs with our desired thickness and displayed number by text printing function. Then we converted an image to hex code and added them to the code and displayed the image by bitmap function. Then we used draw lines function to change the style of the image. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We created a function which accepts numbers as input and displays them as a pie chart. We just use draw arc and filled circle functions.

In this template, We added a converted image to code and then used two black and white arcs to create the pointer of volumes.  Download the .h file and add it to the folder of the Arduino sketch.

In this template, We added a converted image and use the arc and print function to create this gauge.  Download the .h file and add it to folder of the Arduino sketch.

while (a < b) { Serial.println(a); j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 255, 255)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

while (b < a) { j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 0, 0)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

In this template, We display simple images one after each other very fast by bitmap function. So you can make your animation by this trick.  Download the .h file and add it to folder of the Arduino sketch.

In this template, We just display some images by RGBbitmap and bitmap functions. Just make a code for touchscreen and use this template.  Download the .h file and add it to folder of the Arduino sketch.

A few weeks ago, I wrote this article about using a text variable as an array, either an array of strings or an array of numbers, using the covx conversion function in addition for the latter, to extract single elements with the help of the spstr function. It"s a convenient and almost a "one fits all" solution for most use cases and many of the demo projects or the sample code attached to the Nextion Sunday Blog articles made use of it, sometimes even without mentioning it explicitly since it"s almost self-explaining. Then, I got a message from a reader, writing: "... Why then didn"t you use it for the combined sine / cosine lookup table in the flicker free turbo gauge project?"105 editions of the Nextion Sunday blog in a little over two years - time to look back and forth at the same time. Was all the stuff I wrote about interesting for my readers? Is it possible at all to satisfy everybody - hobbyists, makers, and professionals - at the same time? Are people (re-)using the many many HMI demo projects and code snippets? Is anybody interested in the explanation of all the underlying basics like the algorithms for calculating square roots and trigonometric functions with Nextion"s purely integer based language? Are optimized code snippets which allow to save a few milliseconds here and there helpful to other developers?Looking through the different Nextion user groups on social networks, the Nextion user forum and a few not so official but Nextion related forums can be surprising. Sometimes, Nextion newbies ask questions or have issues although the required function is well (in a condensed manner for the experienced developer, I admit) documented on the Nextion Instruction Set page, accessible through the menu of this website. On top of that, there is for sure one of my more than 100 Sunday blog articles which deals not only with that function, but goes often even beyond the usual usage of it. Apparently, I should sometimes move away from always trying to push the limits and listen to the "back to the roots!" calls by my potential readers...Do you remember the (almost) full screen sized flicker free and ultra rapid gauge we designed in June? And this without using the built-in Gauge component? If not, it"s time to read this article first, to understand today"s improvements. The June 2022 version does its job perfectly, the needle movement is quick and smooth, and other components can be added close to the outer circle without flickering since there is no background which needs constantly to be redrawn. But there was a minor and only esthetic weak point: The needle was a 1px thin line, sometimes difficult to see. Thus, already a short time after publishing, some readers contacted me and asked if there were a way to make the needle thicker, at least 2 pixels.Recently, when playing with a ESP32 based NodeMCU 32S and especially with its WiFi configuration, I did as (I guess) everybody does: I loaded an example sketch to learn more about the Wifi library. When you set up the ESP32 as an access point, creating its own wireless network, everything is pretty straightforward. You can easily hard code the Wifi name (SSID) and the password. But what about the client mode ? Perhaps one needs to use it in different environments. And then, a hard coded network name and password are definitively not the best solution. Thus, I thought, why not use a Nextion HMI for a dynamic WiFi setup functionality?Although the Nextion MIDI I/O interface  has been primarily designed as an add-on for Nextion HMI screens to transform these in fully autonomous MIDI devices as shown in previous blog posts here, it is also of great use for any Arduino based electronic music project! Many MIDI projects for Arduino suffer from a lack good hardware support. There are sophisticated code, excellent libraries and an infinity of use cases, but afterwards, things tend not to work in a rather rough environment in the studio or on stage. That"s because two resistors and a few Dupont wires on a breadboard besides the Arduino are not really an interface which could drive your Synth, Sequencer, or Drum machine over a 5m long MIDI cable.

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.

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.

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.

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.

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.

TFT LCDs are the most popular color displays – the displays in smartphones, tablets, and laptops are actually the TFT LCDs only. There are TFT LCD shields available for Arduino in a variety of sizes like 1.44″, 1.8″, 2.0″, 2.4″, and 2.8″. Arduino is quite a humble machine whenever it comes to process or control graphics. After all, it is a microcontroller platform, and graphical applications usually require much greater processing resources. Still, Arduino is capable enough to control small display units. TFT LCDs are colorful display screens that can host beautiful user interfaces.

Most of the smaller TFT LCD shields can be controlled using the Adafruit TFT LCD library. There is also a larger TFT LCD shield of 3.5 inches, with an ILI9486 8-bit driver.

The Adafruit library does not support the ILI9486 driver. Actually, the Adafruit library is written to control only TFT displays smaller than 3.5 inches. To control the 3.5 inch TFT LCD touch screen, we need another library. This is MCUFRIEND_kbv. The MCUFRIEND_kbv library is, in fact, even easier to use in comparison to the Adafruit TFT LCD library. This library only requires instantiating a TFT object and even does not require specifying pin connections.

TFT LCDs for ArduinoUser interfaces are an essential part of any embedded application. The user interface enables any interaction with the end-user and makes possible the ultimate use of the device. The user interfaces are hosted using a number of devices like seven-segments, character LCDs, graphical LCDs, and full-color TFT LCDs. Out of all these devices, only full-color TFT displays are capable of hosting sophisticated interfaces. A sophisticated user interface may have many data fields to display or may need to host menus and sub-menus or host interactive graphics. A TFT LCD is an active matrix LCD capable of hosting high-quality images.

Arduino operates at low frequency. That is why it is not possible to render high-definition images or videos with Arduino. However, Arduino can control a small TFT display screen rendering graphically enriched data and commands. By interfacing a TFT LCD touch screen with Arduino, it is possible to render interactive graphics, menus, charts, graphs, and user panels.

Some of the popular full-color TFT LCDs available for Arduino include 3.5″ 480×320 display, 2.8″ 400×200 display, 2.4″ 320×240 display and 1.8″ 220×176 display. A TFT screen of appropriate size and resolution can be selected as per a given application.

If the user interface has only graphical data and commands, Atmega328 Arduino boards can control the display. If the user interface is a large program hosting several menus and/or submenus, Arduino Mega2560 should be preferred to control the TFT display. If the user interface needs to host high-resolution images and motions, ARM core Arduino boards like the DUE should be used to control the TFT display.

MCUFRIEND_kbv libraryAdafruit TFT LCD library supports only small TFT displays. For large TFT display shields like 3.5-inch, 3.6-inch, 3.95-inch, including 2.4-inch and 2.8-inch TFT LCDs, MCUFRIEND_kbv library is useful. This library has been designed to control 28-pin TFT LCD shields for Arduino UNO. It also works with Arduino Mega2560. Apart from UNO and Mega2560, the library also supports LEONARDO, DUE, ZERO, and M0-PRO. It also runs on NUCLEO-F103 and TEENSY3.2 with Sparkfun Adapter. The Mcufriend-style shields tend to have a resistive TouchScreen on A1, 7, A2, 6 but are not always in the same direction rotation. The MCUFRIEND_kbv library can be included in an Arduino sketch from the library manager.

The 3.5-inch TFT LCD shield needs to be plugged atop the Arduino board. The Mcufriend-style shields are designed to fit into all the above-mentioned Arduino boards. The shields have a TFT touch screen that can display colorful images and interfaces and a micro SD card reader to save images and other data. A 3.5-inch TFT LCD touch screen has the following pin diagram.

How project worksThe code fills a rectangle, then draws a rectangle within which text “EEWORLDONLINE” is displayed. Then, lines, circles, rectangles, and squares are drawn on the screen. The project ends with a greeting and a message.
