CC2650STK: Pdm2pcm16k() source code?

Part Number: CC2650STK
Other Parts Discussed in Thread: CC2650

Dear all,

 

my customer is currently using the CC2650 SensorTag and wants to increase the sample rate for audio data from 16k to 48k or even higher.

Is there a way to get the source code of the pdm2pcm16k() function to adapt it to higher sample rates?

 

Thanks,

BR,

Matthias

    Hi Matthias,

    We are not able to provide the source code of the psm2pcm16k function. Even if we could I don't think it would provide much help as the implementation is highly optimized for this conversion and raising the sample rate would likely require changes through out the whole routine.

    There is nothing fancy to the source code itself in terms of the algorithm used so it should be quite easy to make their own implementation using common pdm to pcm algorithms that could match our driver.
