Daniel Lee / Mbed OS DISCO_F413ZH-AUDIO-demo

Initialized for DISCO_F413ZH audio example

Dependencies:   BSP_DISCO_F413ZH

This is a simple Audio loopback code for DISCO_F413ZH.

The base repository is https://os.mbed.com/teams/ST/code/BSP_DISCO_F413ZH/. I've added workaround patch for Audio-in and out(loopback) demo on DISCO_F413ZH board(Microphone U16, U17)

https://os.mbed.com/media/uploads/Daniel_Lee/img_9603.jpg

If you connect a 5x Mems microphone, the Audio-in path (U16 and U17) going to be automatically changed to 5x Mems microphone.
