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.
