Details
This function selects the user display screen and displays the given text.
After the instrument is turned on, the first time you use a display command to write to the display, the message
"User Screen" is cleared. After the first write, you need to use display.clear() to clear the message.
The display.clear(), display.setcursor(), and display.settext() functions are overlapped,
nonblocking commands. That is, the script does not wait for one of these commands to complete. These
nonblocking functions do not immediately update the display. For performance considerations, they update the
physical display as soon as processing time becomes available.
The text starts at the present cursor position. After the text is displayed, the cursor is after the last character in
the display message.
Top line text does not wrap to the bottom line of the display automatically. Any text that does not fit on the current
line is truncated. If the text is truncated, the cursor is left at the end of the line.
The text remains on the display until replaced or cleared.
The following character codes can be also be included in the text string:
Display character codes
Character Code Description
$N
Newline, starts text on the next line. If the cursor is already on line 2, text will be ignored
after the $N is received
$R
Sets text to normal intensity, nonblinking
$B
Sets text to blink
$D
Sets text to dim intensity
$F
Sets the text to background blink
$$
Escape sequence to display a single dollar symbol ($)
Example
display.clear()
display.settext("Normal $BBlinking$N")
display.settext("$DDim $FBackgroundBlink"
.. "$R $$$$ 2 dollars")
This example sets the display to:
Normal Blinking
Dim BackgroundBlink $$ 2 dollars
with the named effect on each word.
