Source

void start() {
    pinMode(BACKLIGHT_PIN,OUTPUT); // Set the backlight pin as an output
    tft.reset(); // Resets the TFT
    uint16_t ID = tft.readID(); // Different TFT controllers may be used, this identifies the controller model
    tft.begin(ID); // Inits the TFT screen
    if(ID==0x9325) // This only works with ILI9325. for other controllers, you need a different command.
        tft.WriteCmdData(0x2B, 0x000E); // Set frame rate to 112 fps. Used for better look in screen off animation Remember to change this low-level command to match your controller
    delay(100); // Wait a little to rest the shield (may not affect anything)
    tft.setRotation(Orientation); // Sets rotation to predefined value
    tft.fillScreen(page_backColors[CurrentPage]); // Fills the screen with the firt page's color. Filling with black before it only wastes time.
    navigatePage(0); // Draw the first page.
    analogWrite(BACKLIGHT_PIN,brightness*BC); // Activate backlight
