OR1200, Github, Touchscreen

I worked out the kinks that I was tracking down. Turns out that while I was going to change the clock edge of my RAM after I found the kink I should have just done it anyway. I was corrupting random memory with every write, fun times.

So here is where I am placing code now:

I am using the TerASIC Touch Screen for my user interface. This is finally hooked to the processor in some fashion. At time of writing the ping pong buffer is only partially implemented and the off chip ram is not yet used at all. This means it just displays one line of the screen across the entire screen. It also does a small animation to make sure it is working.

I hope to have the off chip RAM and procedural images by the end of the week. Then I can move onto the SD Card and PNGs.
