Description: Arduino Mega Touch Screen GUI– In this video tutorial, you will learn how to create a simple touch screen GUI using Arduino Mega TFT 5 inch Touch LCD. // o fato de termos rotacionado a tela para landscape implica no X receber o mapeamento de Y Be sure to set the screen size in the sketch to the appropriate size and upload it to your Arduino. Project tutorial by Nick Koumaris. tft.println("FERNANDOK.COM"); For such projects, you can use an Arduino and a Touch Screen Display. I first came across this touchscreen which offers a resolution of 320×240 pixels, and an easy to use micro SD slot among several other great features on banggood.com and decided to buy it for use in some of my projects since it was inexpensive as it only costs around $11. About this screen. }. void createTriangle() } //objeto para manipulacao dos eventos de toque na tela You can tweak the contrast later if needed. tft.fillCircle(240, 125, 30, GREEN); }. #define FEEDBACK_TOUCH_Y 200 To do so, you should upload the following code on your Arduino board and open the serial monitor. }. //faça um código simples para imprimir os valores (x,y) a cada toque TSPoint p; const int circle_x = 240; Be sure to check the datasheet or look for labels on your particular LCD: Also, you might need to solder a 16 pin headerto your LCD before connecting it to a breadboard. Plug in the USB connector of the Arduino to power the LCD. tft.setTextSize(TEXT_SIZE_L); float triangleArea(TSPoint a, TSPoint b, TSPoint c){ Phones, tablets, self-serve kiosks, bank machines and thousands of other devices we interact with make use of touchscreen displays to provide an intuitive user interface. tft.setTextSize(TEXT_SIZE_L); //objeto para manipulacao dos eventos de toque na tela Created by @njh. Arduino Uno and Visuino: GPS Location display with GPS and TFT Touchscreen Display Shields - Quick and Easy! #define WHITE 0xFFFF These values are important for mapping the touch to the graphic points on the screen. The objective of today’s lesson is to specifically address the graphic and touch screen features of this display. One is to use an Arduino's hardware SPI interface. #define TS_MINY 80 You'll see a graphics test program run, showing drawing lines, text, rectangles, ellipses, triangles, etc. Touch Screen interfacing with Arduino December 14, 2016 Arduino Tutorials , Uncategorized arduino , interfacing , LCD , touch screen Manoj R. Thakur Resistive touch screen displays are composed of multiple layers that are separated by thin spaces.

C: / Program Files (x86) / Arduino / libraries. Pages: [1] 2 3. } It also comes with micro SD slot and 4 MB flash so you could add it easily to your projects with this 2.8" TFT Touch screen. We have to make sure that the Arduino is informed via UART when the two buttons are pressed. MAR3501(have touch screen)/MAR3502(have no touch screen) Screen Size 3.5(inch) Type TFT Driver IC ILI9486 Resolution 480*320 (Pixel) Module Interface 8-bit parallel interface Active Area 73.44*48.96(mm) Module PCB Size 85.49*55.63(mm) Operating Temperature -20℃~70℃ Storage Temperature -40℃~70℃ Operating Voltage 5V/3.3V pinMode(XM, OUTPUT); If so, check out the video today, where I will show you an assembly with a Mega Arduino and a Touch Screen Display. The screen will start drawing dots where your finger was. The drawTriangle function is responsible for drawing a triangle on the screen, passing the point of the 3 vertices. Works with all Arduinos and Teensy. #define MINPRESSURE 10 initialSettings(); } This TFT Touch screen is a fantastic shield with big (2.8" diagonal) and 240x320 pixels with individual pixel control which could apply to Arduino and mbed. You will see how to make the designs you want on the screen, and also how to determine the screen region to touch and activate a specific command. //chama a função para iniciar nossas configurações OSOYOO 3.5 inch touch screen is designed to work with Arduino UNO/Mega2560 board. if( p.x >= 10 && p.x <= 90) { tft.setTextColor(WHITE); We create a rectangle, a triangle, and a circle with the origins we determine. #define RED 0xF800 Compatible with Arduino UNO and Mega2560, and can be connected directly by inserting the pin into the interface without wire. Follow the diagram below to wire the LCD to your Arduino: The resistor in the diagram above sets the backlight brightness. (5)Offer support with Arduino libraries, simplify program development. }. 1.2. This is an addition to my post about the Touch Screen Shield for Arduino UNO, so if you’ve landed here, that may be a good place to start for more information.. Several people have asked about using this touch screen shield with the Arduino Mega, but I didn’t have much advice to offer because I didn’t own a Mega until yesterday. float distance = sqrt( pow(p.x - circle_x,2) + pow(p.y - circle_y,2)); } } This function checks if the point is inside the rectangle. writeShape("Triangle"); delay(1000); //inicializa objeto controlador da lib grafica //posicionamento dos textos de feedback #include //Portas de leitura das coordenadas do touchvoid //se a distancia do ponto pra origem do circulo for menor ou igual ao raio, ele está dentro Fast and easy. Before we start our program, we need to address something important: the TOUCH calibration. Then touch your desired location and write the coordinates displayed on the serial monitor. void createRect() #define TS_MAXY 900 //max/min X do retangulo The other is to declare all the pins manually. //verifica se a pressão no toque foi suficiente A touchscreen GUI for Arduino can be created in a few lines of code. }, //distancia entre pontos D = raiz( (xb-xa)^2 + (yb-ya)^2 )//vefifica se o ponto está dentro do circulo The fillScreen function is responsible for filling the screen with a single color. // Função que verifica se o ponto p esta dentro do triangulo ABC// Se estiver dentro retorna TRUE senão retorna FALSE #define TS_MAXX 900 Let's also create an example containing all the elements, such as positioning, writing, designing shapes, colors, and touch. // Função que calcula a area de um triangulo com base nos pontos x,y tft.println("SHAPE: "); Before we start our program, we need to address something important: the TOUCH calibration. In them I put videos every week of microcontrollers, arduinos, networks, among other subjects. (6)With Micro-SD card circuit, easy to expand the scope of the test. I am getting quite comfortable with utilizing the screen, however I have hit a wall when it comes to actually programming touch screen buttons to run functions. Follow my channel on Youtube and my Blog. const int circle_radius = 30; This website is Open Source, please help improve it by submitting a change on GitHub: }. }. if( p.y <= 150 && p.y >= 100) Unzip the file and paste it into the libraries folder of the Arduino IDE. if(pointInRect(p)) { writeShape("Rect"); This sketch is using the SI4735 library developed by Ricardo PU2CLR. Learn: how touch sensor works, how to connect touch sensor to Arduino, how to code for touch sensor, how to program Arduino step by step. #define TS_MINX 130 Arduino Mega2560 5 inch TFT HMI touch screen Programming: Before you start the programming, first of all, download the libraries used in this project. About: Do you like technology? //então encontre os valores nas extremidades max/min (x,y) The screen can be configured for use in two ways. Navigate to sketch and include the libraries. Run the Arduino IDE and clear the text editor and copy the following code in the text editor. //Portas de leitura das coordenadas do touch#define YP A1 // Y+ Serial.print("X: "); Serial.println(touchPoint.x); There is no difference in the functionality of the screen between the two methods, but using hardware SPI is significantly faster. //cria um triangulo com os vertices: tft.drawCircle(240, 125, 30, WHITE); tft.setRotation(1); tft.drawTriangle(110, 150, 150, 100, 190, 150, WHITE); float ABP = triangleArea(a, b, p); tft.setTextColor(WHITE); The drawPixel function is responsible for painting a single point on the screen at the given point. Now rotate the potentiometer until one (16×2 LCD) or 2 rows (20×4 LCD) of rectangles appear. "Touch screen" Click on the links and download the libraries. #define TEXT_SIZE_S 1 tft.setTextSize(TEXT_SIZE_S); In this tutorial, a variable resistor will be used as the sensor to display its value on the HMI touch screen. //cria um retangulo com origem (x,y) = (10,100)//width = 80 e height = 50 } Install the IDE software as instructed. void loop() { TSPoint touchPoint = ts.getPoint();//pega o touch (x,y,z=pressao) This is the 4-wire resistive touch screen firmware for Arduino.
