Sentences that have# prefix are called pre-proccessor directives. If you have included in your SoPC Builder system a LCD controller, the system.h file defines LCD_DISPLAY_BASE macro , so code below conditional compile sentence is included, if macro is not defined, code is not included.

# ifdef LCD_DISPLAY_BASE

staticvoid lcd_init( FILE *lcd )

{

fprintf(lcd, "%c%s Video Coding ", ESC, ESC_TOP_LEFT);

# endif

staticvoid initial_message()

{

printf("* Hello from Nios II! *\n");

}

# endif
