Talon876 / TD_GUI

A basic Arduino library for creating buttons.

TD_GUI

A basic graphics library for use with the 2.8" TFT Capacitive Touch Shield for Arduino.

It builds on top of the Adafruit libraries: Adafruit_ILI9341 (for graphics) and Adafruit_FT6206 (for touch input).

Basic Usage

//create the two adafruit classes you will need to pass in to the button
Adafruit_ILI9341 gfx = Adafruit_ILI9341(10, 9);
Adafruit_FT6206 touch = Adafruit_FT6206();

//create the button, passing in an x and y location, width, height, and amount of padding
TD_Button button = TD_Button(30, 10, 220, 80, 4);

void setup() {
    Serial.begin(115200);
    
    //start the adafruit classes
    gfx.begin();
    touch.begin(40);
    //rotate screen 90 degrees so it's horizontal
    gfx.setRotation(ROTATE_90);
    gfx.fillScreen(BLACK);
    
    //assign button pressed and released handler methods
    button.onButtonPressed = &buttonPressed;
    button.onButtonReleased = &buttonReleased;
    //setup primary and secondary colors for the button
    button.primaryColor = GREEN;
    button.secondaryColor = DARKGREEN;
    //initalize the button
    button.init(gfx);
}

void loop(void) {
  //update the button so it can redraw itself and call the pressed/released handlers when it's touched
  button.update(touch, gfx);
}

void buttonPressed() {
  //do something when button is pressed
}

void buttonReleased() {
  //do something when button is released
}
