It relies on Robot.beginTFT().
drawCompass() uses debugPrint(), which can't be used in the same sketch.
Use drawCompass() properly to avoid elements overlapping.
degrees: int between 0 and 359. Typically it's determined by Robot.compassRead().
Robot.beginTFT();//Initialize the TFT module
Robot.drawCompass(compassValue);//draw the compass
