The following programming example illustrates how to position the cursor on row 2, column 1, and
then read the cursor position:
display.setcursor(2, 1)
row, column = display.getcursor()
print(row, column)
Output:
2.00000e+00 1.00000e+00
Displaying text messages
To define and display a message, use the display.settext(text) function, where text is the
text string to be displayed. The message starts at the present cursor position. The following
programming example illustrates how to display Test in Process on the top line, and Do Not
Disturb on the bottom line:
display.clear()
display.setcursor(1, 1, 0)
display.settext("Test in Process")
display.setcursor(2, 6, 0)
display.settext("Do Not Disturb")
Character codes
The following special codes can be embedded in the text string to configure and customize
the message:
•
$N
Starts text on the next line (newline). If the cursor is already on line 2, text is ignored after
the '$N' is received.
•
$R
Sets text to Normal.
•
$B
Sets text to Blink.
•
$D
Sets text to Dim intensity.
•
$F
Set text to background blink.
•
Escape sequence to display a single "$".
$$
In addition to displaying alphanumeric characters, you can display other special characters. Refer to
Display character codes
codes.
The following programming example illustrates how to display the Greek symbol omega (Ω):
display.clear()
c = string.char(18)
display.settext(c)
