xpctargetspy - Open Real-Time xPC Target Spy window on host PC

Syntax

MATLAB command line

xpctargetspy
xpctargetspy(target_object)
xpctargetspy('target_object_name')

Arguments

target_object	Variable name to reference the target object.
target_object_name	Target object name as specified in the xPC Target Explorer.

Description

This graphical user interface (GUI) allows you to upload displayed data from the target PC. By default, xpctargetspy opens a Real-Time xPC Target Spy window for the target object, tg. If you have multiple target PCs in your system, you can call the xpctargetspy function for a particular target object, target_object.

If you have one target PC, or if you designate a target PC as the default one in your system, use the syntax

xpctargetspy

If you have multiple target PCs in your system, use xpctarget.xpc to create the additional target object first.

target_object=xpctarget.xpc('mode', 'arg1', 'arg2')

Then, use the following syntax.

xpctargetspy(target_object)

If you have a target PC object in the xPC Target Explorer, you can use the following syntax.

target_object=xpctarget.xpc('target_object_name')

The behavior of this function depends on the value for the environment property TargetScope:

• If TargetScope is enabled, a single graphics screen is uploaded. The screen is not continually updated because of a higher data volume when a target graphics card is in VGA mode. You must explicitly request an update. To manually update the host screen with another target screen, move the pointer into the Real-Time xPC Target Spy window and right-click to select Update xPC Target Spy.

• If TargetScope is disabled, text output is transferred once every second to the host and displayed in the window.

Examples

To open the Real-Time xPC Target Spy window for a default target PC, tg, in the MATLAB window, type

xpctargetspy

To open the Real-Time xPC Target Spy window for a target PC, tg1, in the MATLAB window, type

xpctargetspy(tg1)

If you have multiple target PCs in your system, use xpctarget.xpc to create the additional target object, tg2, first.

tg2=xpctarget.xpc('RS232', 'COM1', '115200')

Then, use the following syntax.

xpctargetspy(tg2)
