Audio Player Demo (STM32L4R9I-DISCO)

[Du1]

I would like to implement audio in my project with the STM32L4R9I-DISCO kit. I tried first checking out the demo that comes with the discovery kit, but the touchgfx demo doesn't seem to accept wav or mp3 files. Is there a specific audio format that it will only play?

The 2nd question is then, is there example code to enable the audio demo? I see the files are already in the generated touchgfx project (audio_player_app.c/h, audio_if.c/h, audio.h, and stm32l4r9i_discovery_audio.c/h).

Thank you!

I'll just post the l4r9-touchgfx demo project here as well. See if you can find what you're looking for in there.

Thanks a lot Martin! I'm going through it now and it's already very helpful to see how it was setup.

That's good to hear, @Du​!

Hi Martin,

We have a project using STM32L4R9 with 480*272 display. Could you please share the TouchGFX 480*272 display demo project of STM32L4R9I-EVAL ( I have this board ) ? Thanks a lot !
