This is really a couple of questions that have come in from a customer.
1. The MIC input is what gives us trouble . . the 20 dB boost bit makes no difference in either position, and I don't get the expected level of data inside the DSP, as evidenced through the graphing feature of Code Composer. The right and left line inputs operate as expected. Is there anything special I need to do other than setting the MIC bit in the "Analog Audio Path Control" register?
2.We started working with this CODEC about three years ago, on recommendation of some associates. Although I have written code that appears to work, I have never been convinced that I have the correct interface between it and the DSP, which we have used for a longer period of time (albeit, an older family member - '5402). The CODEC is set up to operate in the Right-Justified Mode . . only because I could never get it to work in the DSP Mode, which the data sheet says is compatible with TI's McBSP ports.
I there TI documentation that outlines the proper setup of these two devices in the preferred mode(DSP Mode), perhaps including sample code, that would be helpful.
Cheers
