Hi guys,

does anyone have or know of a utility to convert a file consisting of a load of 8-bit binary numbers into their equivalent decimal numbers? I'd whip up something myself, only I don't have a complier at the moment. :down:

Any help would be appreciated.

    Alrighty, anyone with a C compiler? I have no idea if this will even compile, but could you try this?

    PHP:
    #include <stdio.h>
    #include <file.h>
    
    int main(void)
    {
      FILE *fp1;
      int i, data[1000];
    
      fopen(fp1, "psd.txt", "r");
      for(i=0; i<1000; i++){
         fscanf("%d", &data[i]);
      }
      fclose(fp1);
      fopen(fp1, "psd_dec.csv", "w");
      for(i=0; i<1000; i++){
         fprintf(fp1, "%d,", data[i]);
      }
      return(0);
    }

    Don't know jack about c myself, but gcc doesn't like it:

    Code:
    $ gcc bin.c
    bin.c:2:18: file.h: No such file or directory
    bin.c: In function `main':
    bin.c:16: warning: passing arg 1 of `fopen' from incompatible pointer type
    bin.c:16: error: too many arguments to function `fopen'
    bin.c:20: warning: passing arg 1 of `fscanf' from incompatible pointer type
    bin.c:20: warning: passing arg 2 of `fscanf' from incompatible pointer type
    bin.c:26: warning: passing arg 1 of `fopen' from incompatible pointer type
    bin.c:26: error: too many arguments to function `fopen'

    Okay, I think this is better:

    PHP:
    #include <stdio.h>
    #include <file.h>
    
    int main(void)
    {
      FILE *fp1;
      int i, data[1000];
    
      fp1 = fopen("psd.txt", "r");
      for(i=0; i<1000; i++){
         fscanf("%d", &data[i]);
      }
      fclose(fp1);
      fp1 = fopen("psd_dec.csv", "w");
      for(i=0; i<1000; i++){
         fprintf(fp1, "%d,", data[i]);
      }
      return(0);
    }
