Guys,

I tried to display f_size on FATFs,
I want to retrieve file size.

code :
Code: 
Code:

DWORD   fsize;         /* File size */

 usart_pstr(" ");
            sprintf_P( &temp_buffer, PSTR("file size => u\n"), fno.fsize );
            usart_pstr( &temp_buffer );

but the result is different with I see on file size my computer

on uart :
Scan directory mp3
AIRSUP~2.MP3
file size => 15012
AIRSUP~3.MP3
file size => 63616
AIRSUP~4.MP3
file size => 29023

at my computer

Directory of G:\mp3

3 File(s) 16,491,651 bytes
2 Dir(s) 978,108,416 bytes free

G:\mp3>

Any clues ?

thanks
 

sprintf_P() is no standard C function and "file size => u\n" contains no valid format specifier.
On a 16bit compiler %u is usually needed to print word data and %lu for dword.
