Enhanced read_wishbone.c

Daylan

Curious as to why someone left an unused 'unsigned short i' in .../logi-apps/wishbone/sw/read_wishbone.c I figured it had to have been an original counter value (.i.e.,  number of words to read index).
So I modified the code (shown below) to be able to read (if specified) multiple words from the command line (i.e., "./read_wishbone 0x0000 20". )

Modified main() function from ../logi-apps/wishbone/sw/read_wishbone.c:
--------------------------------------------------------------------------------------------------------
int main(int argc, char ** argv){
    int fd, address, words=1 ;
    unsigned short i ;
    unsigned short readVal[256];
    if(argc  < 1){
        printf("not enough arguments \n");
        return 0 ;
    }
    address = (int) strtol(argv[1], NULL, 0);
   if ( argc > 2 ) words = (int) strtol(argv[2], NULL, 0);
   if ( words > 256 ) words = 256;
    wishbone_read((char*)readVal, words*2, address);
   for( i=0; i < words; i++ )
   {
      printf("0x%x 0x%x \n", address+i, readVal[i]);
   }
    return 0 ;
}

Nice ! i will make the change to the code on the repository.
