I am using the STM32H735G-DK development kit to evaluate the LiveTune audio kit capabilities.

When connecting to the dev board it shows several audio input source but does not show one for the Line Level input on connector CN11.

How do I use the Line Level Input with the LiveTune software?

Only options shown are

  • SysIn-MicroPDM
  • SysIn-Microphones
  • SysIn-USB

    Hello @euanbrown  

    After connecting your STM32H735DK board to the LiveTune platform, please follow the steps below using the terminal and the provided screenshots:

    cli>ac audio : List all configuration available. ( screenshot 1)

    cli>ac audio 13 : Select the Mic:Line  as configuration and reboot  ( screenshot 2 )

    -->  Now, the LineIn configuration is complete. 

     

    Recommendation: I recommend using the Guitar effect example for optimal use of Line Input with the LiveTune software in our Audio Kit firmware. This example is located in the folder: Middlewares\ST\Audio-Kit\examples\livetunedataflow\References\guitar .

    For more information about Audio Kit examples, a list of LiveTune dataflows is provided as examples along with short documentation for each one.

    Additionally, I recommend checking the documentation for further assistance with your future projects using the X-CUBE-AUDIO-KIT. You can download it from ST.com and follow this path:Middlewares\ST\Audio-Kit\docs\refman .

    Regards
