This is a very tiny Quartus II project that shows the bare minimum configuration you need to be able to design FPGA logic programs, run them on the chip, and even store them in the on board EEPROM (If your board isn't the cheapest version that has no EPCS4 memory chip on the bottom of it).

I'll write more here when I get a chance. Basically, you need a USB Blaster clone (I prefer the white cased one because it allows Device Discovery), and a little understanding of FPGAs and what exactly you're doing.

There are some good tutorials around on the web but I'll throw what I can in here when I get the chance.

ctrl-l (that's an L)

Assignments -> Pin Planner then change the Location field. Recompile after you change pin assignments

Tools -> Programmer then select you hardware, then press Device Detect OR (if device detect stalls for 30 seconds) just manually add the EP2C5T144 device

This is the pain in the butt one that I'll write up later. You need to convert the .pom output from your compile step to a .jic file first.

Once that's done, Tools -> Programmer then make sure you go to View -> Show Device Tree then... so on

Actually, all of this is kinda described in: https://www.altera.com/en_US/pdfs/literature/an/an370.pdf
