Requires building firmware with PlatformIO, running a bundle script, and flashing to the device, plus a FAT32 SD card inserted before first boot.

in plain english

PaperOS is a small operating system built for the M5Stack Cardputer, a pocket-sized computer with a physical keyboard and tiny screen. It bundles a launcher, file manager, drawing app, text browser, game emulator, music player, offline AI chat, 3D editor, and Lua programming console into one firmware. The developer calls this the first public release and openly lists rough edges and known bugs. Installing it requires building the firmware with PlatformIO, running a script that bundles everything into a single file, and flashing that file to the device. A FAT32 SD card must be inserted before the first boot. Updates from older versions need a full reflash rather than an incremental one, because the partition layout has changed. Each app has its own folder structure on the SD card: games go in /games/, music in /music/, 3D models in /3d/, and saved browser pages in /saved_links/. Paint can open and save files anywhere with any name. The apps cover a surprising range. File Manager recognizes file types and opens them in the right viewer instead of showing garbled text. Paint supports pen, shapes, fill, eraser, eyedropper, and text tools. Games run NES, Game Boy, Game Boy Color, and Arduboy titles, with the emulator flashed to a spare slot on first launch. Browser is text-only with no JavaScript, CSS, or images. Music plays WAV and MP3 files with volume and play controls. The myAI app is a small language model trained from scratch on TinyStories, running fully offline. The device has no RAM to hold the model, so it reads weights from the SD card for every character it generates. Replies are slow and short by design, with a live counter on screen so it does not appear frozen. The 3D Editor handles OBJ mesh files with orbit and vertex editing. The Lua console is a real Lua 5.4 environment with APIs for filesystem, networking, graphics, input, sound, timers, and more. Known issues include browser lag on large pages, occasional bookmark menu lag, untested heavy Lua scripts, and image viewing that depends on a library feature not guaranteed on every version. The developer asks for bug reports with screenshots and a description of what happened.

prompts (copy fr)

prompt 1

I have an M5Stack Cardputer and want to install PaperOS. Walk me through building the firmware with PlatformIO, bundling it into a single file, and flashing it to the device, including how to prepare the FAT32 SD card.

prompt 2

Help me organize files and folders on my PaperOS SD card so games, music, 3D models, and saved browser pages are all in the right directories the OS expects.

prompt 3

I want to write a Lua script for PaperOS that uses the graphics and timer APIs to display a moving animation on the Cardputer screen. Give me a starter script and explain how to run it in the Lua console.

prompt 4

Explain how the offline myAI app on PaperOS works and why it reads weights from the SD card for every character. What should I expect when using it, and how do I know it hasn't frozen?
