Feed in data into PIO, or other Interface

Hello,

first i like to know what kind of Programm you want to write!

There are a few posibilities to access a PIO

- You can write a *.c Project in the NIOS II IDE but it is nessesary that your PIOS are included and generated in your NIOS II SoPC Builder.

- The other way is to write a Hardware description either in VHDL or Verilog. You have to read and understand the Avalon Bus Specifications because you build a Avalon Bus Slave Component and NIOS acceses to your Component over the Avalon Bus.

To your Question with the EPCS pleas read the Handbook to the NIOS SDK. You can use the NIOS Shell to generate a *.flash code from your *.edif code. This is nessesary to programm your flash.

Hope this was helpful.
