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

Posted on January 09, 2014 at 05:08 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.
