Audio and Inter-IC Sound (I2S)
The ARTIK modules are designed for a variety of purposes. From the outset, the Samsung engineers knew that many developers would want to integrate them into some kind of Audio product or infrastructure. The ARTIK is equipped with Inter-IC Sound (I2S) serial buses for delivering audio samples to a stereo audio codec chip on the developer reference board. You can implement this same chip in your own hardware designs. Layered on top of the kernel support for I2S are the ALSA SDK, library, and toolkit for managing sound recording and playback.
