Tool/software: Code Composer Studio
I am trying to evaluate a digital PDM microphone using TLV320AIC3253EVM-K. I have attached the microphone to J6 of the evaluation kit. I have removed jumper W15. All the other jumpers and switches are correct.
I tried using the Spectrum Analyzer miniDSP app of AIC3253EVM-K CS, but I am not getting any signal there. Then in the Typical Configurations I selected Digital Microphone Loopback and tried again, but still no signal in mini Spectrum Analyzer. Are there any other settings I need to change to view the spectrum ?
Also when I am clicking on 'Program Spectrum Analyzer into miniDSP' and 'Load Spectrum Analyzer' buttons, nothing is happening.
Please guide me how can I get the mini Spectrum Analyzer working.
Thanks and Best Regards,
