      1 /*
      2 Tests string alignment
      3 
      4 Normally strings are printed relative to the top left corner but this can be
      5 changed with the setTextDatum() function. The library has #defines for:
      6 
      7 TL_DATUM = Top left
      8 TC_DATUM = Top centre
      9 TR_DATUM = Top right
     10 ML_DATUM = Middle left
     11 MC_DATUM = Middle centre
     12 MR_DATUM = Middle right
     13 BL_DATUM = Bottom left
     14 BC_DATUM = Bottom centre
     15 BR_DATUM = Bottom right
     16 
     17  
     18  Needs fonts 2, 4, 6, 7 and 8
     19 
     20  Make sure all the display driver and pin connections are correct by
     21  editing the User_Setup.h file in the TFT_eSPI library folder.
