Frame Buffer and Text Generation now working…

Now that I have the 4MB SRAM board installed, I now have a frame buffer that can keep up with the video bandwidth rate.

The resolution and color depth is currently 800 x 480 x 12-bit. The computing shield I’m using only supports 12-bits, but my LCD can do 24-bit.

Essentially how my frame buffer works is that you write the 12-bit color value into an address in memory that corresponds to a location on the screen.
