Hello experts , I have a query on how to acquire a PCM audio 2000 to 4000 samples nearly from a PDM out conversion of a MEMS mic and display them on UART/USART for every 2 or 5 seconds? Can any expert help me with a coding part. Thanks in advance
MEMS mic -ICS43432+ STM32f4xx nucleo board.i have given a 168MHz HSE clock configuration and used a PDM2PCM middleware too with a 32KHz audio frequency with I2S in master receive mode. and DMA in SPI2_RX DMA1 Stream 3, in the STM32Cube MX.The oscillo...
