USB DRIVER FOR IMAQ

[Brad]

Hey Nuno,

If you're using the latest USB installer (http://zone.ni.com/devzone/cda/epd/p/id/5030), you will notice an input on the USB Init VI called Video Mode. You can wire a numeric to this input and the camera will be opened using that video mode so when you acquire, you can get 640x480 without launching the configuration dialog box. You can figure out which number to use by opening the dialog box that lets you select Video Modes and seeing which index the video mode you want is (it is 0 based).

Hope this helps,

Brad

Thanks Brad.

Meanwhile I changed Peter's Code so that it worked for 640x480, but I like the Imaq usb version better, so your tip was pretty much usefull.

Cheers and a Happy new Year for all.

Hi Brad, I am waiting for the solution of the problem with USB camera driver. Since the problem, for the polish language, was applied by "aftek" (2006.03.06) nobody confirmed that this driver works fine with the new DLL, for the polish version. As I know from NI PL guys - it still does not work. I am using WIN XP SP2 polish and I get the same popup window (as aftek - see page 4. of this thread): P.r.z.e.c.h.w.y.t... Could you, please, try once again new DLL for Poland. Thank You in advance. Best regards Marek

[Brad]

Polish has already been added and I double checked the spelling, and it looks good, so one of the later DLLs after the page 4 post should work.  I'm posting the latest DLL just in case, so let me know if you're still having problems with Polish.

Thanks,

Brad

Hi Brad,

thank you for so quick reaction. I am sorry to tell you, that  with the  DLL, you enclosed today, my camera does not work.
I work with Dell Latitude D505 , OS WIN XP SP2 PL,  LV7.1 .
Exactyly the same LV instalation I have on another DELL Latitude D620 but with WIN XP SP2 ENG
and the camera works fine.
I enclose the "error message" I received today.
I have tested on the USB example "Grab.vi".

I would be very happy if I could use my notebok + camera in ca 1-2 weeks (I need it for a presentation).
Thank you in advance for your help.

Hello Brad,
is it possible, that the string in the popup window is not full? There is no polish word "Przechwyt"  but there is "Przechwytywanie" =  "interception".  May be WIndows showes a part of the string "intercep..." ?.  Could you create a DLL with the string "P.r.z.e.c.h.w.y.t.y.w.a.n.i.e." ?

I changed the Polish string to what you mentioned. I'm not sure why the entire string wouldn't be displayed, but hopefully that is the problem. Let me know how this works for you.

Thanks,

Brad

Hi Brad,
thank you once again. My idea was wrong. The DLL sent  with the message  137 did not help.
So I have no more ideas what to do next.
Thank you.
Have a nice weekend.
Regards
Marek

I think I found what the problem was. I need a period at th end of the word because I think it's an abbreviation

I changed the string to this: Przechwyt. instead of Przechwyt

Let m know how this works for you.

Thanks,

Brad

Hi Brad, do you have sourcecode for this dll?

Is it public? can it be?

I'd like very much to look at it.

Thanks

Nuno

(your tip resulted very good 640x480)
