VI controlled strobe signal output from camera's GPIO port

[Winup]

Hello,  I am using LabVIEW to control a FLEA2 1394b camera. I am running the example VI that allows the user to configure most the attributes of the camera (gain, shutter speed,...). The Flea2 cameras have a 1394b firewire connection to the PC and another General Purpose Input/Output port that can take in input/output signals. The configuration of the GPIO port is stored in the camera's registry. I have used the capture program provided with the cameras to configure an output signal to trigger a stroboscope for the cameras. I would like to do the samething with LabVIEW control. I don't know where to modify the registry values. If anyone has suggestions, please let me know. Thank you!

Hi Winup,

There are IMAQdx VIs which allow you to Read or Write Attributes, which it sounds like you have been able to accomplish with the Example VI.  There are also VIs for Reading and Writing the Register (IMAQdx Read Register and IMAQdx Write Register).  Take a look at these VIs and see if you are able to make the desired changes to the camera's registry using them.  The LabVIEW Help File also provides more information on how to use these VIs.

Thanks,

Hello, I have a working Flea2 CCD camera and a working Labview program to use it. The problem is that I cannot make the the camera to appear in the MAX. It would be very usefull for me if someone writes down several steps how to make the three things (PC, Flea2 firewire camera and a functioning Labview program for it) work together. Thank you!

Hi Peter,

Do you have the IMAQdx driver installed on your system? To use a Firewire camera with MAX and LabVIEW you need the IMAQdx drivers. You can get this driver by installing the Vision Acquisition Software.

Thanks and have a great day.

I used firepro driver by the instalation of the camera - that's why it was not appearing in the device manager and MAX. I have IMAQdx and I managed to run the camera. The next goal is to conver the live video stream to a Intensity matrix so I can fit later.

 Thanks for the reply and if you have some suggestions on the new goal please dont hesitate and let me know.

 Cheers!

Hi there,

To do that, you will need the Vision Development Module.

Thanks and have a great day.

Hi I now  know that there is a example.vi(Image to array) that is doing that. I dont have it even though I have the Vision Development Module.

Could you please upload it.

Regards,

Peter

Hi Peter,

I am sure it should be installed with the VDM. Go ahead and search for it in LV see if you can find it.

Thanks and have a great day.

You were wright it was there. Find example didnt find it but manual seach helped.
