Purpose Display input value using LED digits or numbered wheels
Description Blocks in the Numeric Displays library reflect the numerical value of their
input using graphical elements that imitate either numerals composed of
light-emitting diode (LED) segments, or numbered wheels.
The Odometer block’s displays imitates the numbered wheels of a car’s
odometer or tripometer. An optional reset button on the Odometer block can
respond to a mouse click by setting the display to zero.
To learn how to use and customize blocks in this library, see “Numeric
Displays” on page 3-19.
Note Blocks in this library can display alphanumeric characters if their
DisplayMode property is set to AlphaNumeric. Some blocks, such as the
IRIG Format block, use this alphanumeric mode by default. However,
Simulink signals are always double-precision numeric values. When using the
alphanumeric mode, you can control the display via an M-file S-function that
uses the ActiveX support features in MATLAB. The M-file S-function
ax_strip_sfun.m illustrates this approach; also, see the ActiveX
documentation.
Dialog Box The ActiveX Control Properties dialog box governs the appearance and
functionality of the ActiveX control itself. The table below lists the panels of the
ActiveX Control Properties dialog box.
