Hi.

I have purchased a DAC, AD5686. I have installed Linux driver in raspberry pi. I could see DAC channels in /sys/bus/iio/iio:device0/ and device node, /dev/iio:device0. Please help how to play signal continuously at constant rate though adc channels. As per as documentation given in analog devices Linux wiki page, I can test driver with

  echo 1000 >/sys/bus/iio/devices/iio\:device0/out_voltage0_raw.

But I want to play raw data at constant rate through two channels of DAC. I could find any examples for DAC. I am using Linux kernel version 3.10.18+.

   Thanks in advance.
