Follow my channel on Youtube and my Blog. I emphasize that I chose to use the Arduino Mega due to its amount of pins. Basic code to make Arduino communicate with ILI9341. Now rotate the potentiometer until one (16×2 LCD) or 2 rows (20×4 LCD) of rectangles appear. Compatible with Arduino UNO and Mega2560, and can be connected directly by inserting the pin into the interface without wire. #define TEXT_SIZE_L 3 Here’s a diagram of the pins on the LCD I’m using. Just follow these steps: Go to www.arduino.cc/en/Main/Software and download the software of your OS. tft.setRotation(1); }. Install the IDE software as instructed. The topics we will view in … 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. #define TS_MAXY 900 } { const int circle_x = 240; The drawTriangle function is responsible for drawing a triangle on the screen, passing the point of the 3 vertices. #define TEXT_SIZE_M 2 Basic Specifications Table 1. "Touch screen" Click on the links and download the libraries. The equivalent circuit of the touch module is given in the below diagram. if(pointInRect(p)) { C: / Program Files (x86) / Arduino / libraries. The connections from each pin to the Arduino will be the same, but your pins might be arranged differently on the LCD. So today, I'll introduce you to the Touch Screen display, its graphic functions, and how to grab the touch point on the screen. The drawFastHLine function is responsible for drawing a horizontal line from a point and a width. The drawRoundRect function is the same as drawRect, but the rectangle will have rounded edges. In this tutorial, you will learn how to use and set up 2.4″ Touch LCD Shield for Arduino. tft.fillRect(10, 100, 80, 50, RED); pinMode(YP, OUTPUT); #define FEEDBACK_LABEL_Y 200 Pages: [1] 2 3. #define YM 7 // Y- is on Digital7 Arduino Forum > Using Arduino > Programming Questions > [solved] Problem with debouncing touchscreen buttons; Print.
