Example of Audio data Receiving and Transmitting using Stm32F407G-DISC Board

[Srmssenthil]

Hi,

We need an example configuration code with details of Audio data Received and getting Transmitted using Stm32F407G-DISC Board.

In that example if it could have the details of without using any other External things how to receive the audio data through internal PDM microphone. Then send the audio data and data of internal DAC(CS43L22) to the headphone jack, Followed by connecting the audio data received through the headphone to the disc Board.

 

Thanks,

Hello @Srmssenthil,

 

I recommend you to take a look at Audio_playback_and_record in STM32CubeF4 package under this path 

\STM32Cube_FW_F4_V1.28.1\Projects\STM32F4-Discovery\Applications\Audio\Audio_playback_and_record

This example shows how to use the different functionalities of Audio device CS43L22 and ST MEMS microphone (MP45DT02) by switching between play and record audio using USER button.

Also, I think BSP example under "\STM32Cube_FW_F4_V1.28.1\Projects\STM32F4-Discovery\Examples\BSP" path can help you to use "CS43L22" and "MP45DT02" devices. 

 

I hope these examples can help you!

Thank you.

Thanks for your response!

   It would be of great help if you could share an example which depicts how to read data from MP45DT02 Microphone then use that data as input to CS43L22 on live to validate.

 

 

 

Thank you.
