HI 

 

I made an SOPC and I can load a sound to line out in kit DE2. But I want to load a wave file to the audio codec.  

I use the function : 

File *fp;  

fp = fopen(wav_file,"rb"); 

if (fp==NULL) 

printf("Error: cannot open file \n");  

to open wave file. Some wave files i addded to project and the path and file name i defined. But i didn't work. 

 

What problem i have made? 

:confused::(
