Other Parts Discussed in Thread: CCSTUDIO

Can somebody please guide me how can I use TMS3206416T's internal ADC? What configurations do i need to make before using it and what extra hardware I need to add to do it?

    I am not aware of any on-chip ADC in the C6416T device. If you speak about the C6416T EVM on-board ADC then please refer to the Spectrum Digital Support page:

    I am talking about C6416 DSK's on board ADC. I have read the data manuals but couldn't find anything which can help me out.

    All you need is provided as part of CCS 3.30 and C6416T EVM SW:

    For HW info:
    - The EVM tech reference and schematics provide info on the HW.

    For SW example:
    - The Board support library from Spectrum digtal provides an example that make use of the ADC:
        C:\CCStudio_v3.3\examples\dsk6xxx\bsl
    - The audio DSP BIOS example is an audio loopback example using the Audio codec:
        C:\CCStudio_v3.3\examples\dsk6xxx\bios\audio

    ...etc

    Thanks for the help! I have looked some examples of Codec but it didn't answer me that how can I configure ADC's resolution. Btw I have CCS v3.1.

     

    And about HW, what exactly I want to know is that in the data manual of AIC23 codec its written that there is a 35k Ohm input resistance and VDD should not exceed 3.3V. So what should i do that if I input a 3.3 V signal its voltage is not dropped to 0 across the input resistor.
