I am not yet sure if this is the thing I need to do to acquire data quickly, but from looking at the other DAQ drivers it seems to be. > Are you firing the trigger multiple times?

The problem is that I can't even make the iio_dummy driver work properly, so even if there is a bug in my driver, the dummy driver at least should work. When using my actual driver, firing a trigger doesn't seem to run a scan at all. > Perhaps post an RFC of your driver for us to take a look at? I could certainly do that, maybe tomorrow - but I suppose there is a more general issue with this, if I can't even get the iio_dummy driver to work with the tools provided by libiio and the kernel userspace tools. (It still feels a bit like I am missing some obvious information...) > Let us know if you got this sorted. I've been rather snowed under and > out of touch for the last few weeks! Thanks, I'll do - I am still out of ideas though - but maybe when I look at this again tomorrow (after two weeks of not thinking about it) I'll notice some obvious mistake ;-) (although that's probably unlikely). --- Matthias -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
