Can the AcousticBF beamforming algorithm from FP-AUD-SMARTMIC1 algorithm be used on the entry-level kit of BlueCoin board (STEVAL-BCNCS01V1) to achieve audio acquisition at a sampling rate of 48kHz?

STHS34PF80 how to use Unicleo-GUI with custom board

Hi ST-Team,We want to use the STHS34PF80 for presence detection. I am not very familiar with the sensor, as a just watchedthe webinar about the sensor last Tuesday.I think a good way to check the capabilities of the sensor is the STM32 Open Developme...
