      2  Font draw speed and flicker test, draws all numbers 0-999 in each font
      3  Average time in milliseconds to draw is shown in red
      4  A total of 2890 characters are drawn in each font
      5  
      6  Needs fonts 2, 4, 6, 7 and 8
      7 
      8  Make sure all the display driver and pin connections are correct by
      9  editing the User_Setup.h file in the TFT_eSPI library folder.
