display
functions and attributes
The functions and attributes in this group are used for various display operations, which
are explained in
.
display.clear
Function
Clears all lines of the display.
Usage
display.clear()
Remarks
• This function will switch to the user screen and then clear the display.
• 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.

display.getannunciators
Function
Reads the annunciators that are presently turned on.
Usage
annun = display.getannunciators()
annun
Returns the bitmap value for annunciators that are turned on.
Remarks
This function returns a bimap value that indicates which annunciators are turned on.
The 16-bit binary equivalent of the returned value is the bitmap. For example, assume
the returned value is 1028. The binary equivalent for this value is as follows:
0000010000000100
The above bitmap indicates that bits 3 and 11 are set. From the chart below, bit 3 and
bit 11 corresponds to the annunciators that are turned on (
4W
and
REM
). Notice that
the sum of the weighted values for bits 3 and 11 is the returned value (1028).
