![]() ![]() void drawPixel (int16_t x, int16_t and, uint16_t color) The drawPixel function is responsible for painting a single point on the screen at the given point. ![]() Now let's take a look at some graphical functions that libraries can offer us. Serial.print("Y: ") Serial.println(touchPoint.y) Serial.print("X: ") Serial.println(touchPoint.x) TSPoint touchPoint = ts.getPoint() //pega o touch TouchScreen ts = TouchScreen(XP, YP, XM, YM) objeto para manipulacao dos eventos de toque na tela ![]() #include //Portas de leitura das coordenadas do touchvoid These values are important for mapping the touch to the graphic points on the screen. Using a simple program to get the touch points on the display, store the value of the points (x, y) at each end (highlighted in yellow in the figure below). Unzip the file and paste it into the libraries folder of the Arduino IDE.Ĭ: / Program Files (x86) / Arduino / librariesīefore we start our program, we need to address something important: the TOUCH calibration. Click on the links and download the libraries. ![]()
