DEVELOPMENT OF EMBEDDED SYSTEM FOR REAL-TIME AUDIO ACQUISITION AND PROCESSING BASED ON STM32 MICROCONTROLLER
In the paper, the embedded system for real-time acquisition and processing audio data has been developed using the STM32F407G-DISC1 Discovery kit with the STM32F407VGT6 ARM Cortex-M4 32-bit MCU. The basic modules of the STM32F4DISCOVERY kit are used for its operation. The STM32F407VGT6 MCU I2S2 peripheral module has been configured in half-duplex master mode to acquire PDM data from the MP45DT02 microphone.
