I still haven't resolved my problem with the AIC23 on the TMS320C6455EVM. After viewing the different options available, I tried to use the Data Converter Support by selecting "Codec, Serial interface -> 18-24 bit -> TLV320AIC23: 96kHz, Audio, Stereo -> Aic23_4" and then setting the AIC23 mode to USB and selecting 48/48 kHz sampling rates and insured that the Line Input is activated.

Hi everybody, I have a simple question. I am using the DSK6711 which has an AD535 on board. The AD535 has the sampling frequency limited to 8 Khz. Does this also mean that i will be unable to play out audio through the ad535 at a higher frequency, or is it just that the input analog signal will be sampled only at 8 Khz? Thanks and regards -Sunil

I have seen many examples of connecting an ADC to the McBSP port where the sampling rate is controlled by a clock generated by the DSP chip. I have an application where the clock will come from an encoder connected to the shaft of a motor. I am trying to figure out if there is an efficient way to do this with the DSP architecture. I don't think it can be done using the McBSP. The s...
