What I have (unsuccessfully) tried to convey is that you should test your hardware with simpler software (and "commenting out" big blocks of code is dangerous -- I rarely do it; the time spent on a small fresh program is not wasted) -- take a step before taking the whole trip.  My CGoL program was much smaller than your 16x16 array and yet I still spent a lot of time developing and testing the hardware interface to get it to work.  In the end it's simple, but that's because no one but me was around during the development process.

This iterative, "Here's what I got, what do I do now process?" isn't going to help.  You have to knuckle down and and figure out how to move one lit LED from a corner of the display to the opposing corner.  When you can do that, you will have solved the hardware interface and can move forward with the program.  You may actually have a hardware error.  In my program a 1 bit in the column enabled it, and a one bit in a row turned it on.  The demo above should only have one LED on at a time IF your hardware works as mine did.
