Hi Rick, I am hardware engineer too; Sounds like we are in the same boat:)
I essentially want to build a "radio," so I'll be developing a cape with > audio out and amplifier > I would recommend you to have look at TLV320AIC3100 with class D 4ohm speaker driver. It saves you amplifier design for driving speakers and has stereo Headphone ports. Needless to say, with class D amplifier you get the lowest power consumption possible compared to class AB etc. If you need stereo speaker output consider TLV320AIC3110. (is I2S the same as your "I2c2"?) > No, TI calls I2S, Inter IC Sound, McASP which is a four wire bus. I2C is Inter-Integrated Circuit and is a two wire bus. For codec you need both of them. You need I2C for programming the registers and I2S for transmission of voice. Could I ask you additional questions as I get further into this? > That's what forum is for. It is pretty simple. Just connect your I2C and I2S to micros I2C and McASP, do the procedure that I wrote above, and you are done.
