System setup
14/46
In this mode the STM32 performance line USB demonstration kit records 5 s long audio
sample and than plays it back through any mean (speaker) presented in the above chapter.
In this mode, LD2 blinks at a fast rate when the demonstration kit is recording, and at a
slower rate when the acquired record is being played back. The red LED LD1 functionality
does not change. When LD1 is off the onboard speaker is used for playback, when LD1 is
on the external stereo speakers are used.
