ST25RU3993-EVAL - Where's the buzzer on the board connected?

[MKova.1]

Hi,

I want to use the buzzer on the board as an indicator when the tag gets in the range of the reader and when it gets out. But I can't find anything about it in datasheet, except in the block diagram. To what pin is it connected on the MCU? How can I use it? Am I missing something in the datasheet? Sorry for bothering you all :).

Thanks and kind regards,

Mirnesa

Hello Mirnesa,

you have a nice example of buzzer use in platform.c.

in platform.c, remove all commented line related to playForElise() (lines 83, 173 and the function itself).

upload the FW (now you fixed the issue with the virtual machine ;) )

run it and enjoy ...

regards,

Cedric.
