example, requires about 576 bytes worth of commands to be sent, and could not be
accomplished at any rate less than 2400 baud. Obviously, ramping several objects at
once requires a baud rate several times as high.
Indirect Text - Series 3200 touchpanels support a feature that permits the text field
in any user-defined button to be altered on the fly in RUN mode. This is
accomplished by substituting a text pointer for the text in the button. The text pointer
informs the panel to use the contents of a variable that may be dynamically redefined
as the text field for the button. This presents a considerable advantage over other
methods in that changing screens does not destroy information and that information
may be placed in buttons not currently displayed.
The text pointer is a number in the range of ‘1’ through ‘127’ preceded by the
“pound” symbol (#). If [text…] is omitted, the text field is cleared. If [text…] exists,
it is added to the text field. For example, consider the following string :
#3Now is the time<cr>
#3for all good men<cr>
#3to come to the<cr>
#3aid of the party.<cr>
Assuming that a button with an #3 text pointer was being displayed, the contents of
the button would be changed to:
Now is the time
for all good men
to come to the
aid of the party.
NOTE: To clear the text field for this example, type in “#3<cr>”.
As each line is entered, the display is updated. Since the text may be placed in
several different buttons, no boundary checking is done to see if the text fits in the
button. If the text overflows the button/boundaries, it remains centered in the
button/boundary.
