Implementing VGA display in Nios II Project

Sure... Here's a quick Perl script that reads your bitmap image and creates a C char array from it:

#!/bin/env perl
$file = $ARGV;
open(INPUT, "$file") || die "Failed to open input file!!!  Cannot convert!!!";
open(OUTPUT, "> ext_flash.h" );
# #  Output the variable declaration and set an attribute on it.# 
print(OUTPUT "unsigned char __attribute__ ((aligned(4))) data_buf = {\n");
$i = 0;
while(read(INPUT, $data, 1))
{
  if($i == 0)
    {
      print(OUTPUT "\t");
    }
 # 
 #  Here's the magic...  use unpack to grab the file's data into an unsigned
 #  char variable.
 # 
  printf(OUTPUT "%#02x, ", unpack("C", $data));
  $i++;
  if($i == 10)
    {
      print(OUTPUT "\n");
      $i = 0;
    }
}
print(OUTPUT "};\n\n");
close(FILE);
