hi
 everyone
i m working on TMS320VC5510 dsp processor ,i read a data from function generator and want to
store on a buffer but only one sample is stored ,any body can help me.

while(1)
{
for(k;k<51;k++)
{
while(!DSK5510_AIC23_read16(hCodec,&sample);
x[k]= sample;
}
while(!DSK5510_AIC23_write16(hCodec,sample);
}
x[0] sample will only come when i see it on quick watch window.
regards;

Did you watch x[1]?  Does it change?  What about value of k, does it stop at 1?
