ST B-U585I-IOT02A User Manual

• Wait until the end of the flash procedure. The green LED flashes quickly while flashing, slowly when the
flash procedure is over and successful. A red LED means failure.
The check command on the console might check if the flash procedure is correct. If the user has not seen any
issue during the process, Figure 23 shows completion without error messages.

7.9.1 Two on-board MEMS audio sensor omnidirectional digital microphones (MP23DB01HPTR)
The B-U585I-IOT02A Discovery kit provides two MP23DB01HP digital MEMS microphones. The microphones are
connected to the MCU's ADF/MDF interface. The clock needs to be configurated accordingly. The I/O interface is
described in Table 16.
