This is still a WIP, /snake.S isn't a snake game yet. There are a bunch of sub-projects in /Buildup that I'm using as stepping stones to learn what I need to in order to finish the final game:
Originally, I was using an online development environment & writing in x86 assembly (old files on later commits), however the online environment did not allow for clearing the terminal. As such, I have decided to restart from scratch & work with the 32-bit arm architecture, my rasberry pi is 64 bit, but happily convert & execute the 32-bit instructions. Since all pi's before the 4B are 32-bit & cheaper, I've decided to go this route such that the project is more accessible as example for anyone who would like to learn from it.
Hello worldNullTerm : Null terminated stringsbinStr : register -> ascii binarydebug : print all registers in binaryUI : Displaying a simple UI frame, using pointers for potential accessInput waiting test: Get input without blockingInput loop : more input testing, ran into ANSI term issues here
I was using an online dev environment (over at https://www.jdoodle.com/compile-assembler-nasm-online/) since it's easier than setting up everthing on my windows pc & I wanted to use linux syscalls. However, this tool dosen't accept ANSI terminal codes or scrolling. I need these for clearing the screen for updates, and potentially for colouring to make things a little prettier.
Hitting this problem, I am considering setting up an old laptop with x86 linux, or just re-learning things as needed to use ARM, since I have a raspberry pi that I already use as a server.
