08/14/2024 - github/Masto3DS

I've always loved implementations of modern software on obsolete hardware, so-called 'de-makes'; Remakes, but accomodation the limitations of the system they're being ported to. This is my attempt to make a mastodon client for the 3DS. Luckily, the Mastodon API is enjoyably well-documented online, and the process has gone relatively smoothly when I have time to dedicate to it.

Except for images. The 3ds graphics libraries expect you to process the images locally on your development machine before embedding them in the program. This makes sense for game assets, but is not applicable to emoji's from mastodon. This pre-processing? Something called swizzling. It reorders all the pixels so that pixels that are nearer on the screen are nearer in memory, allegedly improving speed by makeing caching more efficient. However, this means I need to 'pre-un-swizzzle' the images before I display them, which I have working for some image sizes but not others. Apparently the algorithm scales differenly than I expected. Anyway, this will require an amount of work I've been putting of for a while now.

The other problem is fonts/emojis. As best I understand it, the emojis are being processed correctly. It's just that the font that provides the glyphs for those characters is not properly hooked into the text drawing routines. Or something like that. If I remember correctly, the whole program is currently commented out to create a minimal testing framework as I debug this, but it's been a while since I've worked on it.

04/05/2024 - github/Ghost

Quick preface: this description describes the program as it was a couple years ago, and I haven't had time to update it as fully as I would like to. It's close, but most components have been completely rewritten since then and operate with significant changes.

Ghost is a computer archecture I made as a thought experiment, and also as an easy way to introduce people to the ideas of assembly. It's both the definitions I've created, and a collection of python/c++ scripts including an assembler and simulator.

The assembler runs in two passes: the first pass clears comments, resolves shorthand, validates the instructions, and records labels. The second pass fills in the labels, does math, and validates each byte to ensure the hex is ready to be output. Then it's output in a variety of formats. Additionally, the compiler supports basic definitions, data definition, labels/names, 5 different output formats, and a dictionary called 'debugging' that allows you to configure the differrent debugging features.

The other main program is the simulator. It loads each instruction from memory, converts it to it's mnemonic, and executes it in an el/if tower. It automatically process writes to screen memory, key inputs, reads from the random IO device, halts, and breaks. Other assorted tools are: Sublime Text syntax highlighting, downloader to get current information from the notion document, and a few example assembly programs.

06/07/2023 - github/CustomLanguage - Try out here!

I'be been toying with the idea of making a custom programming language. The idea is to have it similar in ease of learning to python, but with stricter typing. So far, I've built a demo in python. Above is a demo that hacks together the python code from github with jsgo.

04/25/2023 - github/M5Stack-Games

This is a random collection on projects for the m5stack, built on vanilla micropython and russhughes's ili9342 library. It looks like he might even be providing pre-compiled mp binary, but I've not tested it.

It contains:

• An SD card library
• A wrapper for the ili9342 library that enforces the SPI speed to work with the SD card
• A button library
• A bootloader! Will look for programs on the SD card and let you run them using cwd to hand off program flow to the main.py in the folder
• Some stolen fonts! I can't remeber at all where I got these from after almost a year
• A copy of tuupola's mpu6886 python driver
• An accelerometer program that draws crosshairs on the screen for different measurements
• An unfinished Space Invaders clone
• A bluetooth keyboard that I programmed and used with Spaceflight Simulator on Android to get rockets to orbit. It's just timings, so it will need to be reprogrammed for your use
• A full Snakey game!
• A 3D maze program that generates a maze and runs a raycaster so you can walk through it! Really slow unfortunatly
• A simple program that opens a wifi access point
• A desktop python program for drawing out sprites

As a rule, the apps in ./sd are finished, those in ./dev are not, and those in ./ are drivers or other tools

03/14/2023 - gate io

This is a super simple app designed to track inventory stock. Items are tracked by their name, modifier (Color, size, etc...), and location. On either the add screen or search screen you can tap an item to filter by that name/modifier.

01/03/2023 - downloads/main.py

Super simple calculator script that uses pythons builtin eval function, but ouputs in hex, binary, and decimal. Super useful for debugging GHOST.

09/06/2021 - downloads/TicTacToe.py

Or, Matchbox Educable Noughts and Crosses Engine. A learning tic-tac-toe playter base on the MENACE concept, which manuipulates the chances of the computer making any given move based on whether that move was included in a previous game's win or loss.
