That data sheet shows the DAC using I2C protocol to clock data into it. The Arduino site has a library of software routines to support I2C called the "wire" library.
Actually the datasheet says the DAC uses the I2S protocol. I figured out it also workes with serial data, but i'm not sure where they are different from eachother. In general i know that ones you outputted the signal you have to send a bit too the data-clock or something like it too "confirm" the data, but i don't really understand the working of this.
Is there anyone with experience in Arduino and the I2S protocol, does it works similar as the I2C protol?
I don't even understand the basics of how too send serial sound data, for instance how can i generate a simple tone like in "playing melodys with an piezo speaker" tutorial in the learning part, but then trough a DAC?
I hope somebody can help me on my way in understanding this.
