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