I am planning to build a HD audio player (with digital output only) using single board computer (such as RPi). Provided I need a SATA connector on-board I decided to use Cubietruck as it exposes A20's I2S pins and allows to connect a SATA device.
I did some research and now I am pretty sure that connecting an I2S device to Cubietruck should not be a problem -> http://hifiduino.wordpress.com/2014/03/07/cubieboard-for-audio/
The question is what other pins/interfaces Digi is using (I'm trying to find any specs)? Is it also utilizing I2C bus? Will I be able to use it with Cubietruck when I connect proper pins?
What possible difficulties can I meet? I won't be using raspbian os but lubuntu probably, are there kernel modules that I can compile with? What I found it is supported starting from kernel version 3.10.23 (source: http://www.hifiberry.com/products/digi-connect-your-external-dac/hifiberry-digi-software-installation/ ).
