Using evk-mimxrt685 development board Need to save the pcm data output from dsp to the buff on the mcu side, for this requirement, which sample should I refer to? Is the dsp carried in it able to fulfill this requirement.
Got the pcm data, need to broadcast from the speakers, which sample to refer to?
Thanks for the answer.
I currently can't get the dsp ide, and the dsp sdk for the DSP side of the development, will the dsp firmware you guys are currently carrying in your samples support me getting the pcm data?
Hi @wei-z8.
You can refer to the dsp_mu_polling project to put PCM in shared SRAM and notify CM33 to get it. To play PCM data, you can check the dmic related sample project in SDK. BTW, there is a similar implementation done by a customer in this thread, you can refer to it: https: //community.nxp.com/t5/i-MX-RT-Crossover-MCUs/Microphone-Data-Capture-Processing-and-Output-via- Lin...
Best regards,
