Do you have any indication the driver successfully bound to the device? Look to see what you have in /sys/bus/iio/devices/ If the driver is connected you can just cat from the relevant files under the deviceX directory. Interrupt driven approaches also possible. Take a look at the tools under tools/iio/ in the kernel source tree. The generic buffer code should dump a pretty formatted version of what is being read form the device and you can pipe that to a file. Jonathan
