Hi Sir,
Could you please share the D-Mic application which go with PDM interface? What is the suggestion of the hardware connection and what we need to do on the SW implementation?
GPI2 for PDM data & GPIO2 for PDM clock?
Or our suggestion method for the connection will be plus?
Thanks,
George
Hello George,
AIC3212 has multiple options for interfacing to digital mics. Please refer to section 2.4.3.5.2 of the Applications Reference Guide.
Typically digital microphone interfacing circuitry connects the clocks to GPIO2 and data lines to GPI2 as shown in the diagram below.
Best Regards.
