There is a driver for this device :

By the way, one thing I did note. Remember me saying printf() was not
slowing anything down( much ) using sysfs, and the iio driver ? Well, using
mmap() and then printf() to display the data. Slows the sample rate by
50%+. Specifically newlines -> "\n" seem to be the biggest culprit.
Anyway, that
