Interfacing with MEMS digital microphone

Hello,I'm using an stm32l151re to interface with mp34dt05-a mems microphone. I'm using it to determine noise level. The communication between smt32 mcu and the sensor is based on I2S protocol with dma. My issue is that my project consists of multiple...

Problems with the PDM2PCM-Lib and a STM32L151

I'm having problems with the PDM2PCM lib and am getting desperate.I have a STM32L151 with an external clock source of 8.192 MHz. The SYSCLK runs with 16.384 MHz. The APB2 (SPI1) runs with 4.096 MHz.I'm sampling a PDM mic with an 8-bit SPI at 2.048 MH...
