Function
Yes
Usage
display.clear()
Details
This function switches to the user screen and then clears the display.
The
display.clear()
,
display.setcursor()
, and
display.settext()
functions are
overlapped commands. That is, the script does not wait for one of these commands to complete.
These functions do not immediately update the display. For performance considerations, they update
the physical display as soon as processing time becomes available.
