So today I finally added support for the SD card, and it’s one of the best features I’ve added to the OS. When you boot the OS, it automatically tries to mount the SD card, and then you can open it, add files, read files, and even unmount it whenever you want.

I also added what I call the Light Debugger. It basically initializes the built-in LED or a NeoPixel, allowing you to debug things like boot status, errors, and other events even when you don’t have the serial monitor open.

I also improved the app installation and app running system. You can now install apps directly from the SD card or run them without installing them first.

I also tried writing a simple Snake game for testing, and it’s working pretty well.

I also tried a little funny experiment: I sent the kernel code to Claude AI and asked it to rewrite it in Rust. And it actually did it! It wasn’t perfect—many things didn’t work—but hey, maybe one day I’ll rewrite the whole OS from MicroPython to Rust. Who knows?

So that’s everything for today, and I hope you like the new updates! :)

What do I want to do tomorrow? I want to make the OS look prettier, clean up the code to make it much easier to read and maintain, update the GitHub page, and maybe even create a simple website with a tutorial explaining how to run it on your own Raspberry Pi Pico.

Love u :3
