Hello,

I need help with regard to extending the 4 microphone architecture of X-CUBE-MEMSMIC to 6 microphones using X-NUCLEO-CCA02M1 and STEVAL-MKI155V3. I have attached the modified BSP driver .c and .h files. Also in audio_application.h I have changed the no. of microphones to 6. I have tried to configure SPI3 for microphones M5 and M6. I see that slave select for both SPI1 and SPI3 are the same and since the slave select is not being used in this case, I know this shouldnt be a problem. Can you please let me know which all part of the code should I look into to get it working for 6 microphones. I have also tried to increase the PDM buffer but have not been successful. I see that PDM data is available on scope on all the 4 microphones but due to changes from my part of the code the data is not being recorded. Apart from the x_nucleo_cca02m1_audio_f4 BSP driver which part I should look into to extend the same to 6 microphone architecture.

Thanks,

Ramya

say:

STM32CubeMX version or tell me solution
