Detailed Description

Example: fetch ADC samples in a ring buffer and save to file.

This file contains an example on how to use the ring buffer mode of libpruio. A fixed step mask of AIN-0, AIN-1 and AIN-2 get configured for maximum speed, sampled in to the ring buffer and from there saved as raw data to some files. Find a functional description in section rb_file.
