AVR in Minecraft!

[tokumei]

This post is partly to gauge interest, but also an announcement.

As my Nublet CPU project comes to a close, I've decided that I want to work on implementing a real architecture in Minecraft. I've narrowed it down to two choices: PIC and AVR. As of now I am leaning toward AVR because there are some really cool tools available like avr-gcc that PIC doesn't readily have, and it sounds like PIC assembly is hell.

Overall, I've written some asm for both processors and I hate to break it to PIC users but writing assembly for PIC is akin to stabbing myself in the face. (Except its not even that efficient, cause you have to more the knife into the working register first (movlw KNIFE), and then you can stab yourself (movwf FACE).)

EDIT: I now prefer AVR.

Yes!

AVR that sounds really interesting. please let me know where I can follow your progress

this thread. might also make a series of posts on my blog ( https://nonemu.ninja ) since that is almost dead

I prefer PIC for MC.

Arm Cortex M0 ?

[tokumei]

Any reason, embi?

My god that is a long instruction set.

Do you know of the specs you are going for?

[tokumei]

I am looking at the smallest line of AVR processors out there, something along the lines of an ATtiny. No more than 2KB program memory (ISP flash) and 512B of RAM. So some caching is definitely going to be involved in this project.

ATtiny has serial inputs and outputs iirc. Are you going to keep those?

May I suggest http://ww1.microchip.com/downloads/en/De...asheet.pdf

[LambdaPI]

So analog not serial

Yes that's the line I was hoping to see done too. I think there might've been some projects posted to the web that got similar specs, or is that unlikely?

Thanks for the AVR resources!

Yes, I am looking at something at about the same scale as an ATtiny. No more than 1-2KB of ROM and RAM.;

Yep!

Noice
I've never actually built anything serial, so if you make this, i would love to see
