Hello
I duplicated a song called "test.mp3" on the SD-Card with this code, using Chans FatFS-Tiny:
WORD br, bw; // File R/W count
int Index=1;
char file[]="test.mp3";
char filetype[]=".mp3";
char prefix[]="Song";
char filename[100]={};
// Open source file on the drive 1
res = f_open(&fsrc, file, FA_OPEN_EXISTING | FA_READ);
// Create destination file on the drive 0
res = f_open(&fdst, filename, FA_CREATE_ALWAYS | FA_WRITE);
if (res) LED_EVENT3(LED2,4);
// Copy source to destination
for (;;) {
res = f_write(&fdst, buffer, br, &bw);
if (res || bw < br) break; // error or disk full
res = f_read(&fsrc, buffer, sizeof(buffer), &br);
if (res || br == 0) break; // error or eof
}
// Close open files
f_close(&fsrc);
f_close(&fdst);
Attention: The Forum software is too dumb to display this as code:
This line is inserted before the second file is opened.
The problem now is: the new mp3, when i play it, has no id-Tag and no length information.
Another strange thing: in winamp the used bitrate is shown while playing. The test.mp3 has a constant bitrate of 320 kbit/s. While playing the copied file though, the rate slowly increased from 290 or so. I just could watch it. It grew from 290 to 300 in 15 seconds or so.
The buffer size, i used for the code is 800.
