Hello,
I have a quick question: how do you rotate text on a tft display with adafruit gfx? does anyone know?

Yes, consult the library documentation for screen orientation commands.

Mr Google knows how to do it

I am surprised that you didn't find it when you searched

I did, but when I tried it it didn't rotate anything

I cannot see anything wrong with the code that you did not post

  tft.setRotation(90);
  delay(500);
  tft.println("Happy spring!");
  delay(10000);
}

Put tft.setRotation(0); in setup() for one.. Then try tft.setRotation(1); To see if it's different.

new question: is there anyway to clear the display? (besides tft.fillRect and tft.fillScreen)

12

Well think about that. What would "clear" actually be?
