Guys,

How to play wav on STM32F4 Discovery?

If I want to play from USB Key,

I enable :

#define MEDIA_USB_KEY

and how to connect USB flash drive to this board ? with adaptor ? the socket is too small for USB flash drive...

I'm reading ''Getting started...'' now it seems to be a cable ....

Is it reading from my PC or from USB flash drive....? I'm wondering ??

Thanks

is it the limit ?

/* Audio file size and start address are defined here since the audio file is

    stored in Flash memory as a constant table of 16-bit data */

#define AUDIO_FILE_SZE          990000

so  I can't play 20Mbytes wav file ?

You have access to the same code and documentation I do. There may well be limits and types of files it can handle (bits, channels, frequencies, etc), or sizes/limits related to the convenience of coding. Some of these might be artificial or arbitrary. I haven't done the analysis.
