• The
display.clear, display.setcursor,
and
display.settext
functions are overlapped, non-blocking commands. That is, the script will NOT wait for one of
these commands to complete. These non-blocking functions do not immediately update the
display. For performance considerations, they write to a shadow and will update the display as
soon as processing time becomes available.
