I'm working on DMT simulation using TMS320C5416 as my final project. I have a problem on making output file. I build this small chunk of program using turbo C and I put it on 5416 "DSK CCStudio v3.1". I can show the output on CCStudio, but the output file always returns empty. The output file exists, but it's empty.
The program list is as the following:
----
#include
#include
#include
#include
#define B 4
#define C 16
#define S 64
#define L 16
#define noise 0.0001
#define sN 0
#define N 16
#define F 32
int (*bits);
FILE *fp;
void a2d()
{
int i,j,k,sisa,hasil,bil,(*p)[B];
float (*z),max,min,temp,qinterval,bagi,(*q),(*x),(*mutlak);
x=malloc (S * sizeof(float));
if(!(fp = fopen("handel.txt", "r")))
{
exit(EXIT_FAILURE);
}
else
{
for(i=0; i
}
fclose(fp);
z=malloc (S * sizeof(float));
mutlak=malloc (S * sizeof(float));
for(i=0;i
if (x[i]<0)
mutlak[i]=(-1)*x[i];
else
mutlak[i]=x[i];
z[i]=mutlak[i]/(16-1);
}
max=z[0];
for(i=0;i
if(z[i]>max)
max=z[i];
}
qinterval=2*max;
q=malloc (S * sizeof(float));
bits=malloc (B* S * sizeof(int));
if(B<=1)
{
for (i=0;i
if (x[i]<=0)
bits[i]=0;
else
bits[i]=1;
}
}
else
{
min=x[0];
for(i=1;i
if(x[i] min=x[i];
}
for(i=0;i
temp=x[i]-min;
bagi=temp/qinterval;
if (bagi-abs(bagi) <0.5)
bagi=floor(bagi);
else
bagil(bagi);
q[i]gi*qinterval;
}
p=malloc (B*pow(2,B) * sizeof(int));
for (k=0;k {
bil=k;
for (i=B-1;i>=0;i--)
{
hasil=bil/2;
sisa=bil%2;
p[k][i]=sisa;
bil=hasil;
}
}
for (i=0;i
for (j=0;j bits[B*i+j]=p[k][j];
}
if(!(fp = fopen("p.txt", "w")))
puts("error");
else
{
for(i=0; i {
fprintf(fp, "%d%d%d%d \n", p[i][0], p[i][1], p[i][2], p[i][3]);
printf("%d%d%d%d \n", p[i][0], p[i][1], p[i][2], p[i][3]);
}
fclose(fp);
}
free(p);
free(bits);
free(z);
free(q);
free(x);
free(mutlak);
}
main()
{
a2d();
}

It's working on turbo C and CCStudio, both result:
--------

I suppose the problem maybe in include library or the 'fprintf' command, but it's just my guess. Cab anyone help me to make an unempty output file?
Thank You very much.
