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.

Testing

1. Import the application into your desktop

You can use Mbed CLI, Online Compiler, and Mbed Studio.

  • In case of Mbed CLI, 

mbed import http://os.mbed.com/users/Daniel_Lee/code/DISCO_F413ZH-AUDIO-demo/

cd DISCO_F413ZH-AUDIO-demo
  • In case of Online Compiler and Mbed Studio, Please click 'Import into Compiler'

2. Compile and program 

mbed compile -t <toolchain> -m <TARGET_BOARD>

(supported toolchains : GCC_ARM / ARM / IAR)

3. Download binary to a target board

4. Open a serial monitor on baudrate 115200 to see the output
