working with the pin planner

Hello,

I spent some time reading, and now understand a bit more. I'm sorry for my initial post which was probably too long. To my understanding, my biggest issue was that I took a .qsf file of another already existing project.

Since it was my first try with quartus, I thought I'm doing right. I expected the .qsf to be just about basic board settings. That's why my pins were already set somehow, and I wondered why everything already had a context to each other and finally gave seemingly senseless errors. When I started w/o a provided settings file, things became much easier.

The pin planner sometimes get your assignments messed up, especially when deleting and recreating pins. You may have a better luck modifying your pin definitions in the assignment editor instead. It's a lot less user friendly, but you have more control, and if a pin name is assigned to two different pins, you can delete one of the two assignments.

Thank you for the hint about the pin planner, though, it's good to know and to keep in mind. Starting with those things can be a bit confusing, at least for me.
