I recently picked up a TI-83 Plus Silver Edition calculator at a flea market for $10. I got it so I could write Z80 assembler code on it. In order to do that, I have to write all the assembler instructions on paper and then convert everything to hex bytes. Then I have to enter the hex bytes in the calculator and compile it. I was wondering if anyone has tried to write a z80 compiler using Codea. I’m not thinking of a full fledged compiler because I don’t plan on writing anything big. I don’t want to key in a lot of hex bytes. I know I can do everything on a PC and download the code to the calculator, but that’s too easy. Maybe I’ll give it a try and see how far I get before I lose interest.
Just finishing up a semester of MIPS and x86 assembly code programming. Enough of that for me for now - I’d like to have time to get all dirty in high-level Codea programming
There are numerous open source z80 compilers available online, so you could try to learn how assemblers work from those. If you just want to write programs without a computer, I would highly recommend Mimas, an on-calc assembler and IDE. If you want/need more calculator help, feel free to drop by Cemetech, a website and forum dedicated to graphing calculator programming and hacking.
@Ivoah Thanks for the links, I’ll have a look at them. I was just looking for something that gives the hex values when compiling z80 instructions. I wrote something with Codea that gives me what I’m after. I add new instructions as I need them. The hard part is keying the hex into the calculator. Mimas look interesting.
