Function Yes
Usage
display.clear()
Details
This function switches to the user screen and then clears the virtual front-panel 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 virtual display. For performance considerations, they
update the display as soon as processing time becomes available.
