Altera_Forum1.the c program i am using is very simple pasted below. I am using Altera monitor program:
# define Switches (volatile char *) 0x0001800# define LEDs (char *) 0x0001810 int main() { while (1) { *LEDs = *Switches; } return(1); } 2. About the pin assignments i imported the assignments (the .csv file which comes with the cd) 3. I am a student at Boston university and downloaded the web edition of Quartus(9.0) which means it is not a licensed version)- Altera_Forum
If your program is downloaded without error from Nios -II IDE, check your pin assignments. Doe's a simple "printf" work?.

as per your suggestions i am following a tutorial in the de2 cd (attached) . everything runs fine until the last step mentioned in the tutorial but my leds dont respond to the switches. what could be the problem?

First, try running a demonstration in de-2 CD (http://www.terasic.com/downloads/cd-rom/de2/de2_system_v1.6.zip).
After, build a simple Nios-II based system in SOPC Builder using on-chip memory. - Altera_Forum
Ummm... Look at the breakdown of the DE2 CD (which you should probably download if you haven't already) on this (http://www.altera.com/education/univ/materials/boards/unv-de2-board.html) page.
Plus, there's a _lot_ of stuff already on Terasic's DE2 page...right? Keep in mind that I don't know _exactly_ what you're looking for so I'm not sure which of these links will satisfy you. Cheers, - Ura - Altera_Forum
The terasic site points me to the Altera site. Can you send me the exact link you are talking about
- Altera_Forum
That document is for Altera development kits. The DE2 is specific to the University program and you should look for documentation there (and on Terasic's website)...first.
