Description:

Everything is working great in this build!  So I will be taking about a week break from this.
Well except single pixel drawing on GPU but more on that later.
I included a Hello World program and a screen clear test program running by default.But I would love to see what programs people can come up with. So definitely fork this and make your own programs for it, and link them in the comments below!

Also I am working on adding more instructions for the cpu and the gpu, let me know what might be useful in the comments and definitely check my in progress updates below!

I am running into an issue with per pixel drawing giving a contention error which doesn't make sense as i have tested the chip. unless the rgb screen col and row pins are also outputs i don't get what is going on.

For now though i'm taking a break from that and working on implementing some more of the OPs.

Here is a list of instructions. I'll add descriptions soon.
