STEVAL-STWINBX1 - overview of the sensing components
The motion sensors communicate with the
STM32U585AI
microcontroller via SPI in order to accommodate the
high data rates, whereas the magnetometer and environmental sensors communicate via I²C. The suitably filtered
signal from the
IMP23ABSU
analog microphone is amplified by a
TSV912
op-amp and then sampled by the
internal 12-bit ADC of the MCU. The signal from the digital microphone is directly managed by the audio digital
filter (ADF) interface of the MCU.
