Okay, good. I found that IC in my research, thought it might be useful. > (is I2S the same as your "I2c2"?) > No, TI calls I2S, Inter IC Sound, McASP which is a four wire bus.

I realized after reading more that "i2c2" must've been the Sitara's I2C bus #2, and that I2S support was provided by McASP. > Could I ask you additional questions as I get further into this? > That's what forum is for.
