@/display-text
Write text to the screen at the given coordinates.
DEV@/tft-device
Colour@/colour
Colour of TXT
Stringstring
The text you want to write on the screen.
Sizenumber
Sets the size of text that follows. The default size is "1". Each change in size increases the text by 10 pixels in height. That is, size 1 = 10 pixels, size 2 =20 pixels, and so on.
XLocnumber
The location on the X-axis you want to start drawing text to the screen.
YLocnumber
The location on the Y-axis you want to start drawing text to the screen.
