arduino 3.5 inch tft lcd paint sketch brands

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.

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./*TFT LCD - TFT Touch CoordinateBased on Librery Examplemodified on 21 Feb 2019by Saeed Hosseinihttps://electropeak.com/learn/*/#include #include "TouchScreen.h"#define YP A2#define XM A3#define YM 8#define XP 9// For better pressure precision, we need to know the resistance// between X+ and X- Use any multimeter to read it// For the one we"re using, its 300 ohms across the X plateTouchScreen ts = TouchScreen(XP, YP, XM, YM, 300);void setup(void) {Serial.begin(9600);}void loop(void) {TSPoint p = ts.getPoint();if (p.z > ts.pressureThreshhold) {Serial.print("X = "); Serial.print(p.x);Serial.print("\tY = "); Serial.print(p.y);Serial.print("\tPressure = "); Serial.println(p.z);}delay(100);}

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.

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.

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.

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 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.

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 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.

Liquid Crystal Display, which we abbreviated as LCD, came up with the combination of display technology with arduino. Touch LCD Shiled, with its 480x320 resolution and TFT model, is designed to provide ease of use and control to arduino projects, as well as to color it. You can view your photos with the SD slot. Also compatible with boards such as Arduino Uno, Leonardo, Uno Plus, Nucleo, Xnucleo.

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.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

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.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

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:
