Specifying Hardware Trigger Information
7-19
Element Description Attributes
can contain zero or more
TriggerCondition nodes.
Specifying Trigger Sources
When you define a hardware trigger, you must define the source (or sources) of the
hardware trigger in one or more TriggerSource nodes. In a TriggerSource node, you
specify values for two attributes: name and id. The value of the name attribute is visible
to users of the toolbox in the display returned by the toolbox triggerinfo function. It is
typically set to some value that is recognized by the device's SDK.
<TriggerSource id="1" name="extTrig">
</TriggerSource>
Specifying Trigger Conditions
When you define a hardware trigger, you must define the conditions that must be met
before the trigger fires. The parent TriggerSource node specifies the trigger. In a
TriggerCondition node, you specify values for two attributes: name and id. The value
of the name attribute is visible to users of the toolbox in the display returned by the
toolbox triggerinfo function. It is typically set to some value that is recognized by the
device's SDK.
<TriggerCondition id="1" name="risingEdge">
</TriggerCondition>
