Hi I have been looking for the sample code to implement the DFSDM using MEMS mic using a Single Data and Clock line. I am using CudeIDE 1.0.2V. The MCU I have H743ZI and the mic IM69D130 using a common Data and Clock lines. Channel 4 using Filter0 and Filter1(using Falling and Rising Edges respectively).
The Sample speed is 48kHz.
The question is the sample code for this configuration?
DFSDM Clock Speed is 60MHz.
PDM Freq 2.88MHz.
FOSR 63
Filter Order Sinc4
There is mention of intervealing but no mention of how to handle this situation?
