Hi Diego, Thank you for your fast reply! I have already set the register 81 to 0xCE and the microphone is delivering data as you can see in the attached file (blue=clk with 2.048MHz, green=pdm data from 2 mics) but I still get no I2S Data. I thought maybe there is something wrong with the used BCLK (512kHz) and WCLK (16kHz) BCLK/WCLK=32 (= number of bit to be send; 16bit*2) because in the data sheet example BCLK/WCLK=64 is used (again sending 16bit*2). Could this be the problem? Regarding to the decimation, ok then I just set the AOSR register to 128 and leave the other registers (21 and 22) at their default value. Best Regards, Mike .
