help nios II

Hi, what did you already made ?

I presume you use NIOS II, SOPC or QSYS, an Altera dev board ?

yes i have these so far.

Did you use Qsys to integrate the system? Is gpio1 top level module?

The code appears hand coded. It can work, but you need to import the gpio1 into Qsys.

LCD and PIO can be readily integrated through Qsys. That is also where NIOS II, along with memory for instruction and runtime storage are instantiated. Since all components are available in Qsys, I am not sure why gpio1 has to be coded this way. After getting system constructed in Qsys, Eclipse IDE can be called out to work on software part.

yes i did. yes it is the top module. yes but in my top level i just add a module for the keypad and i'm having a problem in the eclipse because i'm not familiar to c programming used in eclipse.

thank you.

is this what you are referring? and the other file is a module generated by qsys.

what are the pieces missing that i shall add to finish my project?

can you give some examples related to what i want to do please thank you.

thank you for your help.

in creating this project i used to follow the tutorial of my first nios II the blinking of led.

I was confused of gpio and gpio1. I see how the system is built now.

Seems ok with the system. Are you running it on a development board? Make sure the pins are assigned correctly.

There are a few simple examples like "Hello world" or the one that blinks led. That can be used as a start in eclipse. Are those working? They are good to verify you are on the right track.

thank you sir.

if you dont mind sir, do you have any other examples that might help me aside from hello world and led that blinks? cause i'm just a newbie and i'm having hard time programming in the eclipse.

thanks a lot
