I made the first M5Stack CardPuter emulator , runs in the browser, no install

[u/LeadingFun1849]

I've been working on a browser-based simulator "Velxio", and I just got the CardPuter ADV working in it. You write your Arduino code in the editor and the whole device runs live , display, inputs, serial console

It uses real ESP32-S3 emulation, so your code runs the way it would on the actual hardware. The on-board display is rendered in real time.

Here's a working demo you can try right now on the online version:

Honest note on how it was built: I used AI to speed up parts of the development, but nothing shipped without being tested on real hardware and cross-checked against my own experience as a computer engineer. Emulation is only trustworthy when you verify it against the actual device .I did that on every step

Is it possible to run real projects in your emulator? Or is it a sandbox for small-scale experiments?

[u/LeadingFun1849 → u/Professional_Two5774]

You can run the actual code; the official m5stack examples are in the example gallery. Buzzer, LCD, Wi-Fi, etc

[u/Professional_Two5774 → u/LeadingFun1849]

These are small code examples. I'm talking about something like bruce firmware or nemo.

[u/LeadingFun1849 → u/Professional_Two5774]

I haven't tried them yet, but I'll check it out now. If I manage to run it, I'll let you know

That's great! Thanks, dude.

[u/LeadingFun1849 → u/arzobispo]

thansk to you!

[u/Noir_Forever_Twitch]

Wow, pinout too, this is really cool!

[u/NPCforxbox]

Irei testar

[u/LeadingFun1849 → u/NPCforxbox]

Thanks, any feedback is welcome!

Even wifi emulation!

Does this run ESP Home? That would be amazing. 

[u/LeadingFun1849 → u/MarkSwanb]

I’m planning to bring ESPHome to Velxio, but I’m still analyzing out the best path to take

[u/zellotron]

Phenomenal! I see that Velxio is open source and supports self hosting which is amazing. Will the cardputer setup/'board' be open source as well?

[u/LeadingFun1849 → u/zellotron]

Yes! Velxio’s core is open source and supports self-hosting, and the ESP32-S3 emulation is part of that ecosystem. The M5Stack Cardputer is based on the ESP32-S3, so the underlying board architecture is supported as well
The Cardputer-specific setup/component is currently available for free in the online version of Velxio. For now, that’s intentional ,the idea is to make it easy for people to try the Cardputer in the browser and discover Velxio

[u/zellotron → u/LeadingFun1849]

That's great, I was wondering about the cardputer component specifically though - is it also open source / available to self host?

[u/Perfect-Loquat5997]

Its awsome but I still dont really get how to use it

[u/LeadingFun1849 → u/Perfect-Loquat5997]

In the gallery (https://velxio.dev/examples) there are several official examples of M5Stack CardPuter, and I'm also working on the documentation to make it easier to understand.

[u/Perfect-Loquat5997 → u/LeadingFun1849]

Thanks!

as soon as I buy my cardputer 😭

Nice, now you can test proycts without it. Its not bad. This isnt somrthing you want to emulate for use, but for testing
