I would like to make a routine allowing me to draw traces of different thicknesses.
If all screens start at 0.0 they do not all finish in the same way:
X = 319,399, 479,799
Y = 239,319,271,479
To avoid errors I would like to know the screen used.
Do you know a method ?
If you send the "connect" command it will return the unit information.
