// Draw the QR-code at position [x=50,y=0] with white color and a 2x scale
it.qr_code(50, 0, id(homepage_qr), Color(255,255,255), 2);
// Draw the QR-code in the center of the screen with white color and a 2x scale
auto size = id(homepage_qr).get_size() * 2; // Multiply by scale
auto x = (it.get_width() / 2) - (size / 2);
auto y = (it.get_height() / 2) - (size / 2);
it.qr_code(x, y, id(homepage_qr), Color(255,255,255), 2);
