DA14681 Wearable kit for voice commands

Hello,

Since there is a mic on-board the DA14681 Wearable kit, will it be possible for me to port the voice command encoder from Voice RCU software to the wearable kit ? Or will I run into a hardware issue (ex. wrong audio port), or software issue (low memory ? - i can cut other functions of the demo firmware for that hopefully).

Is there an eval kit with voice-command firmware for the new DA1469x devices planned ? (either voice RCU or wearable form factor ?)

Thank you,

Device:

DA1468x

Hi Vivek,

The DA14585 includes a dedicated PDM/I2S module and a microphone can be connected directly to it. There is no need for an analog to digital converter based on I2S. For DA1469x there is a DSP on board as part of the M33 in case this would be needed. DA14681 doesn’t support a PDM/I2S so I assume that it is not possible to port the Voice RCU software to the wearable kit.

Thanks, PM_Dialog
