IDS peak 2.8.0 / uEye+ firmware 3.33

Specifies the activation mode of the trigger.

Values description

•RisingEdge: Specifies that the trigger is considered valid on the rising edge of the source signal. TriggerDelay can be set.

•FallingEdge: Specifies that the trigger is considered valid on the falling edge of the source signal. TriggerDelay can be set.

•AnyEdge: Specifies that the trigger is considered valid on the falling and/or rising edge of the source signal. TriggerDelay can be set. This feature is only supported by uEye+ cameras (GV and U3 models).

•LevelHigh: Specifies that the trigger is considered valid as long as the level of the source signal is HIGH. This feature is only supported by uEye+ cameras (GV and U3 models).

•LevelLow: Specifies that the trigger is considered valid as long as the level of the source signal is LOW. This feature is only supported by uEye+ cameras (GV and U3 models).

Code example

C++

// Before accessing TriggerActivation, make sure TriggerSelector is set correctly
// Set TriggerSelector to "ExposureStart"

// Get a list of all available entries of TriggerActivation
