hi everybody,
i'm trying to get a sequence of images with the vision functions.
with imaqEasyAcquire() everthing works fine and i get one camera image.
but with:
imaqSetupSequence (sid, images, nbOfImages, skipCount, IMAQ_NO_RECT);
imaqStartAcquisition (sid);
i get only black picture when i try to save one image of the sequence to a .png
my second idea was to check the status of acquisition before saving my image - that produced an endless loop...
best regards,
malte
