lcd_display on de2-Board --> test program

Hello,

now i have added the standard lcd_display (Optrex 16207) to my system. Now, i will test my hardware design, but i have no idea how can i do this.

Can you post some simple courcecode lines, which will simple display the message

"hello world" on my display?

(the display get the adress 0x00004820 and the name "lcd_display" under SOPC)

I have found some code with the following line:

lcd = fopen("/dev/lcd_display", "w");

I think, this is code for a linux OS-System? Is that right?

Please help me...

I´m a newbie, you can see!
