#include <util/delay.h>

#include "lcd.h"

/*

static void
ioinit(void)
{
  lcd_init();
}

//FILE uart_str = FDEV_SETUP_STREAM(uart_putchar, uart_getchar, _FDEV_SETUP_RW);
FILE lcd_str = FDEV_SETUP_STREAM(lcd_putchar, NULL, _FDEV_SETUP_WRITE);


int
main(void)
{
 
  ioinit();


  stderr = &lcd_str;

  fprintf(stderr, "Hello world!\n"); //prints out what you put here

 
}
