interfacing nios with addition modules

Hello,

This is a newbie question. Sorry if this is not the right place to post this.

I am still using the nios 1 core, waiting on the nios 2.

I have an additional module that the nios interfaces with currently and everything seems to work fine. Now what i need is to add an additional control signal to that module so that I can turn on and off certain features from within the nios environment, for example c code with GUI interface to a pc.

I am also the cyclone dev kit from altera. So far it doesn&#39;t seem like I easily hook up a signal from my extra module directly to the nios without using up one of the proto pins... i must be missing something here. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/unsure.gif

thanx for any help on this,

-Quan

    I see the light... I should have read through altera&#39;s literature site. It had a document on PIO and that looks like what I was after.

    Do you interface it with Nios using Avalon BUS?

    Yes, i am interfacing it with the avalon bus and it seems to be working okay as expected.

    This seems almost too easy.
