16-Bit Computer
16-Bit Computer
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.

Custom 16 Bit CPU 34
Custom 16 Bit CPU 34To change sample program, copy a eeprom from the programs tab, and replace the one near the start of the circuit in main with it
to start it, toggle on and off the CLR button down by the clock circuit in Main

Also after about 2 days I successfully coded and implemented Coonways game of life in here in a 16x16 grid(so each grid takes 256 entries in the storage and theres 2 of them)
