blinking leds, problem in code C

hi everybody, i'm a newbie.

I'm trying to design a simple blinking leds pattern by using the red leds array on the DE2 kit using CycloneII ,say the leds array begin to blink from the left to the right.

I've known already about NiosII soft processor and the SOPC buider, but I got stuck in writing code in C. I don't know how to create a time delay in my code :confused: , I wonder if I can use the CLOCK_50 ? and what is the best way to do this ?

please help!

thanks.

    may be this code can help you.

    int delay;

    while(1)

    {

    delay = 0;

    while(delay < 2000000)

    {

    delay++;

    }
