This is a BASIC interpreter port from MMBASIC.

MMBasic was created and refined over many years by Geoff Graham. It is a full-featured, powerful BASIC interpreter used across a wide range of platforms, including the Maximite and Micromite families. Official website and original documentation: http://mmbasic.com

Huge update for my first firmware project. No pentesting features this time. But have you ever considered paying $60 for a hardware 2fa key. Now update Poseiden v0.6.8 introduces fido2 authentication along with passkey functionality. The community has dropped 70 stars on the github, so i know yall are enjoying it.

Please check it out if you haven't. Let me know of any bug, ideas, criticism. Because of the community this project started as a small little idea and grown to be something much doper. Yall enjoyy.

Also check out the live interactive demo. A full ui and feature showcase emulated on a browser based ADV.

Hi Reddit! 👋

I'm Hamachang, a software engineer from Japan. 😎

I've been working on a retro-inspired operating system for the Cardputer ADV called AREA 512.

It's built around FemtoRuby, a lightweight subset of Ruby designed for embedded systems.

With AREA 512, you can write Ruby code directly on the Cardputer, compile it, and run it—all on the device itself. That means you can build applications for the hardware without ever leaving the hardware.

It also comes with several built-in applications, including games and small productivity tools, so you can start exploring right away. 🤖

The project is open source on GitHub. If it looks interesting, even giving it a ⭐ would mean a lot to me!

AREA 512 aims to capture the spirit of classic operating systems, so I'd also love contributions from anyone who shares that passion.

Thanks for reading! ✨

See you around! 🚄

vibe coded most of this. i’ve got 2 kids and work full time so i didn’t have time to sit down and hand write all the code myself, i leaned on AI a lot. but i designed it, tested it, and debugged the hell out of it, and i’m honestly proud of where it landed.
it’s a dual screen OS for the cardputer adv. the thing that started it was honestly just frustration. every cardputer firmware i tried only used the main screen, and that always bugged me. i’m not the guy who came up with putting a second screen on the cardputer, but i wanted something that actually used both. so i grabbed the 3d print files for the screen mount and backplate off makerworld, wired up an ili9341, and started building.
it’s got a wifi CSI radar that picks up motion in the room. it’s not a people counter, just movement, being straight with you. there’s a bunch of games including a little cyberpunk roguelike i made, off grid survival stuff, a tamagotchi pet that ages even while it’s off, a music player, and a launcher that lets you flash bruce, marauder, or ghostesp right from the device and bounce back to purplx on reset. plus the usual EDC bits like a flashlight, notes, and a calculator.
it’s open source, MIT. this is my first real project like this so i’m genuinely open to suggestions, tips, whatever. go easy lol.

Edit: from the looks of it I think I’m going to need to fix a couple of items. Nothing to crazy

Introducing the “C.P.S.” monophonic synthesizer, currently under development.
This synthesizer for Cardputer ADV—developed in collaboration with Claude—allows you to enjoy a variety of real-time sound changes not only by playing the keyboard but also by tilting the Cardputer ADV using its IMU functionality.
Here’s how to use it:

・0–9 keys… Keyboard
・-/= keys… Octave change
・,/. keys… Volume control
・Z/X keys… Bend down/up
・Tab key… Switch menus

About the Menus
MAIN Menu
・This menu is for playing music.
The top of the screen displays the waveform; the bottom-left area shows the note you’re playing on the keyboard, the current octave, and a pitch bend indicator next to it; the bottom-right area displays the IMU indicator, parameters assigned to the X and Y axes, volume, and pitch range.

EDIT Menu
・This is the basic sound editing menu.
Use the ;/. keys to navigate between items, and the ,/. keys to change parameters.
You can adjust ADSR and the filter.
You can select from four filter types: HPF, LPF, BPF, and Notch.

SETTINGS Menu
・This menu allows you to adjust settings for each IMU axis, as well as the pitch bend range and rate of change.
The operation is the same as in the EDIT menu.
Currently available items include Timbre(Waveform Modulation), Vibrato Depth, Vibrato Rate, Tremolo, Volume, Pitch Bend, Bend Up, Bend Down, Bitcrush, Filter, and “Unassigned.”
For the filter, the filter type selected in the EDIT menu is applied.

The various parameters set in the EDIT and SETTING menus are saved in a file named “setting.json” located in the “CPS” folder.
Changes to “setting.json” are saved when you navigate to another menu.
Therefore, please note that if you turn off the power or perform a reset without navigating to another menu, those settings will not be applied the next time you start the device.

The comments in the source code currently published on GitHub are in Japanese.
We plan to switch to English in future updates.
Additionally, the README is currently outdated, and we plan to update it with new content and switch to English in the future.
(UPDATE)I changed the comments in README.md and Main.cpp to English and updated the content to reflect the latest version.

To be honest, there are still some aspects of GitHub that I don’t fully understand yet, and while there are various issues, I’ve released this version for now so that everyone can enjoy it.
Please download the file named “C.P.S.v0.5c.bin” and install it via the Launcher.
I look forward to hearing your feedback.
(UPDATE)I've also posted it on M5Burner!

Github Release Page https://github.com/oldtokage-collab/C.P.S.--Cardputer-SYHNTH--/releases/tag/v0.5c

I did some tinkering and came up with this.

https://github.com/p0rtm0lester/m5cardputer-loader

It stores the firmware on the SDCard and pages/copies it into onboard memory on launch.
the reset button drops you back to loader.
its so far becaues DOOM uses some strange partitioning, its not compatible
Right now i have Bruce, BitPirate, Evil, Porkchop, Marauder and Nemo all loaded on the SD and working.
Take a look, make it better, do cool stuff.
Tested on the Cardputer ADV with a 32 gig SDcard

With Claude’s help, I’m developing a monophonic synthesizer for CardputerADV.
Currently, it’s 100% vibe-coded, so I apologize in advance if you’re not a fan of vibe coding.
Its standout feature is sound control using the IMU; you can set different parameters for the X-axis and Y-axis to control.
In the demo video, I’ve set waveform morphing for the X-axis and vibrato depth for the Y-axis.
Currently, the parameters that can be assigned to the X- and Y-axes are waveform morphing, filter (with options for HPF, LPF, BPF, and Notch), vibrato, pitch bend, bitcrush, and volume.
I’ve only been working on this for three days, and since I’m developing within Claude’s free plan, I think it will take a little while longer to complete.
I’m also learning GitHub, so once I get the hang of it, I’d like to make the repository public.
If you have any other interesting ideas for parameters to assign to the IMU, I’d love to hear them.

P.S.: I’m Japanese and am posting this after having it translated by DeepL.
I’m sorry if the text sounds a bit off!

I added scroll wheel indicator and sound recorder but sound recorder doesn't work I will try hard to get it up and running

I added better ota firmware catalog features and better ui for nodes with scroll wheels. Battery info is on my to do list and charging mode too.

Live on m5burner newest version is not on github yet.
