DE2 LCD display

Here I am posting some very rudimentary code that shows one way to drive the LCD display in the DE2 (very rudimentary code ....)

# include <stdio.h># include <unistd.h># include "system.h"# include "DE2_pio_regs.h"# include "altera_up_avalon_character_lcd.h"

int main()

{

int in, out;

alt_up_character_lcd_dev * lcd;

int len;

len =15;

lcd = alt_up_character_lcd_open_dev(CHARACTER_LCD_0_NAME );

// i 've found CHARACTER_LCD_0_NAME in the system.h file

alt_up_character_lcd_set_cursor_pos(lcd, 0, 1);

alt_up_character_lcd_write(lcd, "SOO REALLY COOL", len);

alt_up_character_lcd_set_cursor_pos (lcd, 0, 2);

alt_up_character_lcd_write(lcd, "... TWICE SO ..", len);

[....]

}

Hope this helps others....

PS I am using Nios II IDE 8.0 and and Quartus/SoPC builder 8.0sp1.

As I was learning how to do this i figured out that the name of some include files has changed.

For instance:

altera_up_avalon_character_lcd.h

used to be:

alt_up_character_lcd.h

Has anyone else noticed?
