Description
| Value | Description |
|---|---|
TRIGGER_TYPE_FREE_RUNNING | Frames are output continuously, driven by an internal trigger that occurs as frequently as possible. |
TRIGGER_TYPE_SOFTWARE | Frames are output when PxLGetNextFrame is called, which generates a software trigger (using the IIDC ONE_SHOT feature). |
TRIGGER_TYPE_HARDWARE / TRIGGER_TYPE_LINE1 | Frames are output on the receipt of a valid external hardware signal (if the camera supports more than 1 hardware signal line, then this type is mapped to the 1st IO line). |
TRIGGER_TYPE_ACTION | Enables the frame acquisition action. When an action command is received, the camera will output one or more frames, according to the trigger settings. See: Action Type |
TRIGGER_TYPE_LINE2 | Frames are output on the receipt of a valid external hardware signal on the 2nd IO line. |
TRIGGER_TYPE_LINE3 | Frames are output on the receipt of a valid external hardware signal on the 3rd IO line. |
TRIGGER_TYPE_LINE4 | Frames are output on the receipt of a valid external hardware signal on the 4th IO line. |
See trigger diagrams of the trigger for various cameras
Notes
Frame acquisition actions (TRIGGER_TYPE_ACTION) support both mode 0 and mode 14 type triggers, using the same parameters as the hardware and software trigger types. Polarity and Delay have no meaning in the context of action triggers, so those parameters are ignored.
