Get aquainted with this webpage and bookmark it: 

http://www.altera.com/literature/lit-nio2.jsp  Basically there are a few ways to interact with with external hardware: 1 - Use PIO ports. These are just regular I/O ports that connect to your NIOS processor and go to the outside world. You can write to them, read from them ,get interrupts from them, etc. 2 - Export part of the avalon bus from the SoPC system so your logic can be accessed from the processor. 3 - Create your own custom component to interface between the NIOS and your hardware.  Jake
