hi to everyone!

i'm newbie with all the altera quartus/nios stuff. i have a dsp cyclone III dev kit (EP3C120F780).

I'm trying to show some characters on the lcd, but it doesnt work and i dont know whats wrong with my design. i 've used sopc to build up the system, and this is how it looks:

I've tried to put the enable signal to the lcd on both pins (ab24 and ac24), but the lcd doesnt shows anything. The code i'm using it's the one that jrierab posted some days ago.

does anyone have an idea of what's wrong in my design?

thanks so muck in advance.
