DA7212 MKRZERO Interface

Hi,

Attached herewith is the datasheet of DA7212 that I have.

Hi Charles,

Thanks for sharing the updated Datasheet of DA7212. Using the datasheet I have written the follwing code on Arduino MKRZERO. In this code the MKRZERO is playing a 16-bit Stereo WAV file and I can listen it on my ARD-AUDIO-DA7212 Audio Shield. But it seems that DA7212 suddenly goes in sleep state and the audio stops. Although MKRZERO is playing the Audio. Furthermore the Audio from DA7212 Module is not Stereo. Kindly help in this regard.

Best Regards,

NIradat.
