16. If the camera is not configured for triggering using Camera Link control line 1, configure it using
the camera manufacturer’s configuration utility. Verify the camera width and height configuration
matches the values entered in the Image Width and Image Height spin boxes. The host VI must be
running for the manufacturer’s configuration utility to be able to communicate with the camera.
17. Once the camera is configured, click the
Acquire
button on the VI front panel. Clicking
Acquire
initiates a single-frame acquisition. If the camera is properly configured, it will not output a frame
until a trigger is provided. Supply a trigger by sending a pulse on TTL I/O 0 or by clicking the
SW Trigger
button. Repeat this step to acquire another image.
18. Click the
STOP
button to stop the VI.
19. Close the VI.
Step 5. Modifying the LabVIEW FPGA Example VI to Add a Threshold
This section demonstrates how to modify the NI 1483 example VI to add thresholding.
1.
Launch LabVIEW. If LabVIEW is already running, select
Help»Find Examples
.
2.
In the Getting Started window, click
Find Examples
to display the NI Example Finder.
3.
In the NI Example Finder window, select
Directory Structure
.
4.
Browse to the example folder for the NI 1483 by selecting
FlexRIO»IO Modules»NI 1483
.
5.
Select
1-Tap 10-Bit Camera with Frame Trigger
, then
