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.

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.
