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.
