Hi,

I've got a question concerning the application note AN2739 (playing audio files with I2S audio codec), using the STM3210E-EVAL board:

When I load the application onto the board, the standard STM32-family-presentation appears. Where is this audio file located and how do I change the audio file playing?

Sorry, if it's a stupid question, I'm not very experienced.

Thank you in advance for your reply!

Danny

DFU PC installation has DFU file manager in its program folder, that can extract and again create the .dfu files. I guess the wav file is added as binary content, so no trouble at all!

See page 21 of the AN :D

It's external NOR in the FSMC iface, preloaded with the presentation data.

Ok the file (wave)is loaded with the DFU demonstration firmware (STM3210E-EVAL_Demo_NORFlash_V2.0.0.dfu) as bin file.

But how do I change the audio file ?

It is a binary file.

How can i change a wave file to a binary file ?

Or how can I store another wave file as the DFU standard wave file ?

greeting

Roger
