Hi!

The iio_dummy test module works now with the iio_generic_buffer test
program :-) (libiio still doesn't do what I want though).
My own driver does recognize the trigger call but does not acquire
data, likely due to a mask that is set to something I don't implement
yet (maybe checking for IIO_CHAN_INFO_RAW was not enough).

In any case, it looks like I need to continuously trigger the
(software) trigger to move data into the buffer - is there any way to
automate that, i.e. by saying "give me X samples" or "acquire data for
3ms"? Or do I always need to trigger from userspace or use a hardware
trigger?

Regards,
