TLV320AIC33EVM Audio analyzer window won't open

Other Parts Discussed in Thread: TLV320AIC33

I have TLV320AIC33EVM-PDK.  I downloaded and installed slac116.zip. TLV320AIC33EVM Evaluation Tool runs and I can see the I2C interface working with the scope hooked to SCL and SDA on J17. When I click the Audio Analyzer button the text changes from OFF to ON but the Audio Analyzer window does not open. What do I need to do to get the window to open?

    This feature was found to be buggy and was disabled in the GUI. Unfortunately, the button was not removed so it looks like it is still there (and as you have discovered, it is not).

     

    We recommend that you use something like Goldwave which is available here:

     

    www.goldwave.com

     

    It can do everything the analyzer did and much more.

    I want to read data from the TLV320AIC33 ADC, not edit songs. Can the TLV320AIC33EVM Evaluation Tool do that?

    The EVM will act as a sound card for the PC. The ADC signals can be recorded on the pc (with GoldWave or any other windows program). This file can be analyzed with any software that you choose (fft's etc...). You can also generate sine waves in windows (with Goldwave or any other windows program) and test the output of the DAC. The GUI is used to control the registers on the AIC33.  The analyzer window in the GUI just generated a sine wave on the PC for playback through the DAC (which GoldWave can do) and displayed the input to the PC from the ADC (which, you guessed it, GoldWave can do).

    I finally figured that out and got data from the tlv320aic33. It would have been helpful if the docs said that somewhere.

    Now to get it to work with the  LM3S9B92

    Thanks,
