void convert()

{

  int s;

  lcd_cmd(0x81); 

  delay(2);

  lcd_data_string(“output:”);

  s=test_final/100;

  test_final=test_final%100;

  lcd_cmd(0x8a);

  if(s!=0)

  lcd_data(s+48);

  else

  lcd_cmd(0x06);

  s=test_final/10;

  test_final=test_final%10;

  lcd_data(s+48);

  lcd_data(test_final+48);

  lcd_data(‘ ‘);

  if(shift>16)

   {

      lcd_cmd(0xc0+(shift-1));

      lcd_data_string(” “);

      shift=0;

   }

  lcd_cmd(0xc0+(shift-1));

  lcd_data(‘ ‘);

  lcd_cmd(0xc0+shift);

  lcd_data_string(“CALIBRATE IT”);

  delay(30);
