The interrupts indicating a change would provide the iio_trigger and that would result in the buffer being filled. This allows you to poll/select on the data arriving. The BMC100 driver currently under review does something very similar with a motion detector interrupt so that data is only captured if significant motion is going on. >> >>>> events are created on certain conditions (you are not interested in all samples) >>> >>> And this would be more like e.g. "tell me once I have 100 lux or more" ? >> >> yes > > cool thanks.
