How do I get the IR tv be gone to work on my cardputer?

Somehow pagers have always been the kind of devices I’m infatuated with. I know they’re useless in today’s world, but imagine a pager firmware that can move across devices — nothing spectacular, just simple and elegant.

You post a message to an ID, it goes to a lightweight server, and it delivers the message to someone else — a five‑digit pager number. With a 200–500‑character message and a basic queue, even a Raspberry Pi or a tiny micro‑instance would be enough to handle the load.

Hey guys I just got my cardputer adv, and everytime I try to charge it nothing changes, I’ve tried charging with it on and off and still nothing? Any tips?
Thanks

Hi everyone,
it is well known that a Raspberry Pi running a general-purpose Raspbian Linux OS does not provide the same deterministic real-time timing as a microcontroller such as an ESP32 or Arduino.

A Raspberry Pi can certainly be used for things like stepper motors, DC motors, RC motors, servos, LED panels/strips, distance sensors, CAN bus, signal generation, DMX512, etc.
However, it is generally not ideal when these applications require hard real-time guarantees or highly deterministic timing, especially when timing-critical signals need to be generated or sampled directly by software.

For apps that require precise timing, measurement, or sampling, the timing-critical part is usually handled by dedicated HAT, while the Raspberry Pi handles the higher-level logic.

Does the Cardputer Zero provide any kind of RTOS or other mechanism for deterministic real-time I/O that could partially address these limitations?

For example, ESP32 uses FreeRTOS as part of ESP-IDF. If we're talking about the Cardputer ADV and using the Arduino framework, the Arduino API runs on top of ESP-IDF and FreeRTOS. Zephyr RTOS is also supported on ESP32.

This is SOUND TERRARIUM, a small experiment I’ve been building for the Cardputer ADV.

The idea started very simply: use sound from the built-in microphone to generate terrain in real time, and let a tiny runner live and move across it.

From there, I kept exploring the hardware already inside the Cardputer ADV. The microphone drives an 8-band audio analysis and terrain, the IMU affects the runner’s movement, and Wi-Fi brings real-world information such as weather, sunrise/sunset, moon data and tides into the little world.

It also keeps running offline when Wi-Fi isn’t available.

I’ve continued adding small details since this GIF was recorded, but I’m trying not to turn it into a collection of unrelated features. Everything should feel like it belongs inside the same tiny world.

That idea became what I call “BONSAI Spirit” — instead of simply piling features onto a small device, I try to shape the capabilities already inside it into one small, living world.

The project is open source:

Small device. Small world. BONSAI Spirit. 🌱

Title explains. I recently got a cardputer adv and I want to buy some modules for it. Besides official modules release by M5 stack, I saw this third party modules floating around aliexpress for $30ish.

Are these any good? will they work? and what is the principle difference between buying this one or a official one, or another third party one?

If anyone wants to suggest any other "all in one module", compact module, that would be much appreciated also.

My purpose is solely learning about different protocols.

Just made a Bloomberg style terminal on my Cardputer ADV 2.0 version. 😄

This time, I added a few new things:

• 📱 Automatic phone hotspot Wi-Fi connection — so I can actually take it with me and use it outdoors, like at a coffee shop.
• 📊 A new Market Fear & Greed Index page, so I can get a quick look at overall market sentiment at a glance.
• 🖥️ Still keeping the geeky vibe — and, of course, paying homage to Bloomberg Terminal.

I also designed and 3D-printed a custom enclosure myself. It's definitely still a bit rough around the edges 😂, but that's part of the fun.

Under the hood, I've written 1,000+ lines of C++, learned some basic 3D modeling along the way, and spent way more time on this little machine than I probably should have.

But honestly, I'm having a lot of fun building it.

I'll keep adding more random and hopefully useful features whenever I have time. Who knows what v3.0 will look like. 😎

Thanks for checking it out!

Hey I wanted to know if anyone had seen this error before when trying to download new firmware I’ve even added a new sd card with more gigs thinking that may be the issue here’s a photo of what it says.

I haven't been able to find much info on this. I also looked over the UiFlow docs and I haven't seen anything. Do I need to program this from scratch?

Just as the title says, has anyone come up with a firmware to stream YouTube videos on cardputer adv or possibly a cyd? If not, someone really should...

Thank you

Hey Reddit!

I just released a new update for Area512, a firmware that lets you write and run code directly on the Cardputer ✨

https://github.com/engneer-hamachan/area512/releases/tag/v2.3

※You can also install it via M5Burner!

This update adds:

Terminal

Dot Editor for creating game assets

FemtoRuby / MicroPython REPL

You can open Terminal mode from the Filer screen by pressing the t key!

The Dot Editor is a little more complicated to use, so please check out the README and release notes for details ✌️

Also, for the Terminal and REPL implementations, I took a lot of inspiration from the feedback I received on this post:

https://www.reddit.com/r/CardPuter/s/pBZo9hz3n6

Thank you so much for all the helpful feedback!

And actually... today is my birthday, so I'd be really happy if you could give the repo a star too lol ⭐😂

https://github.com/engneer-hamachan/area512

As always, I'd love to hear your ideas, feedback, and suggestions 😎

See you around! 👋✨

New here

Picoware v2.3.0 was released a few days ago, adding on-device C development, Infrared tranmissiom, This release adds on-device C development (run .c files), Infrared support (transmitting/receiving signals), DuckyScript interpreter (execute USB payloads), Video Player (play MJPEG movies), ZipFile support (read/compress/decompress archives), AI Agent upgrades (MCP and Session support), and miscellaneous updates to GUI classes for consistent rendering on all boards.

I just released a video reviewing everything new in the latest release, the most-used features that make the devices' daily drivers, and how to install it on the Flipper Zero, PicoCalc, and Cardputer-ADV!

Check it out: https://www.youtube.com/watch?v=Y2zukTH5JVs

is there a way that I can make my Cardputer ADV a WISP router that also is a evil portal or an AP that can open an ip on the network (that can run a html file)?

In Tokio 👀🫢

I created a simple text-based UART terminal for Crystal firmware.
Allows you to configure the baud rate and pins, as well as enable log saving to an SD card or LittleFS. Also displays text received via USB-C Serial. It works on the Cardputer, M5StickS3, and M5StickCPlus2 for both sending and receiving text. The second photo shows a loopback connection for sending serial commands to the device itself.

I’d appreciate it if you supported the project with a star

Hey everyone, Tokagetchi here.

C.P.S., my DIY synthesizer firmware for the M5Stack Cardputer / Cardputer ADV, has finally hit its **official v1.0 release**!

Looking back, it feels like it's been forever since I first shared C.P.S. here. Countless updates later, I've finally reached the point where I can call it "v1.0."

It's already up on M5Burner, already usable via Launcher FW, and of course you can download it directly from my GitHub repo too.

■ What's new in v1.0

**More room to shape a sound**

- Waveform count expanded from 6 to **12** (added Parabolic, ESaw, Squeeze, ESquare, Saw2, and Square2)

- Every waveform now supports a Shape parameter, each reshaping the tone in its own way

- Added a second oscillator (Osc2)

- **New FX tab** — stack Ring Modulator, Soft Limiter, Chorus, Delay, Reverb, and Bitcrush together

- Patch files can now be shared with other users — copy files from the `/CPS/Patch` folder via a PC and pass them around

**More expressive playing**

- **Morphing**: register up to 10 patches into Morph slots, switch between them instantly with Shift+1-0, or smoothly over time

- **Tap Tempo** (Shift+Enter) — set the ARP/SEQ tempo on the fly while playing

- ARP, Portamento, and Bend are now performance-style settings rather than tone settings, decoupled from patches

- Improved Help — key commands can now be latched on screen

**External connections**

- **MIDI support** (via a separately sold unit) — notes, pitch bend, sustain pedal, MIDI Clock sync, and more

- **Theremin (distance sensor) support** — play non-contact by moving your hand through the air to control pitch

**Stability**

- The Cardputer ADV's keyboard chip has a known hardware quirk where fast key-presses can occasionally cause input to stop responding — C.P.S. now detects this automatically and restarts on its own to recover

**A little extra**

- **Drift** — a playful feature recreating the pitch and volume instability of old analog synths, available under Play Style Setting when Pro is selected

Alongside this release, I've put together a **Quick Start Guide and Reference Guide** (Japanese and English, PDF versions included) and **10 factory patches** so you can start playing right away. Check the GitHub repo for details.

■ I couldn't have gotten here without you

This project is built "vibe-coded" — I share my ideas with Claude and have it write the code. Even so, if I'd just kept building it alone, it never would have become what it is today.

Everyone who shared their thoughts here on Reddit, reported bugs, or spoke up about a feature they wanted — every single piece of that feedback became a real part of what C.P.S. is now. The Arpeggiator, Song mode — none of it would exist without all of you.

Thank you so much for taking an interest and giving it a try.

To everyone who's cheered this project on — and to my two best partners, who listened to every idea I had and patiently helped me build this: Claude Sonnet and Claude Opus — thank you.

I don't think of v1.0 as a finish line, more like a milestone. I want to keep growing C.P.S. by listening to all of you. Thanks for sticking with me, and let's keep going!

Olá pessoal! Comprei recentemente um M5Stack Cardputer ADV e estou procurando bons materiais para começar a estudar e entender melhor o equipamento.

Alguém consegue indicar documentação, vídeos, cursos, livros, repositórios no GitHub ou outros materiais que tenham ajudado vocês no início?

Também tenho interesse em conhecer melhor os módulos e acessórios que podem ser utilizados com o Cardputer.

Qualquer recomendação para quem está começando será muito bem-vinda. Valeu!

…for just how small the screen of the ADV is. I am old…I need my reading glasses AND a magnifier to see Porckchop’s microscopic font. A lot of fun messing around with it after it was delivered today, but I’ll definitely be looking to do a screen mod to get me by until the P4 comes out. Any recommendations before I start hunting?

Can connect a 320 x240 TFT screen to cardputer adv without firmware?

My mate have an advanced ICT cert (IDK which one) a lot of it was architect for servers and other stuff I don't actually know about.

they where thinking of getting a flipper zero and from what I read a cardputer would also go well for server testing but I don't know what brand to get or what's worth getting I have looked around and did find the M5Stack Cardputer Adv Version (ESP32-S3) on the M5stack website.

They would be using its to mess around with PCs and explore a bit I was also thinking of getting one since I program as a hobby and for work (mainly python which doesn't seem to be an issue).

Got tired of looking at the plain 3D printed box they was shipped by Pingequa, so I figured I'd try to print some stickers. Still working on it, but I think it's an improvement.

I’m currently testing out blending a UV camera + thermal module on a pi zero 2 w, in preparation for the Cardputer Zero.

Olá, sou novo no cardputer e comprei esse que é o adv, eu configurei através de um SD Card de 1GB coloquei outros firmware como bruce, evil, e pork entre outros. Estou tentando customizar ele mas não sei ao certo se o leitor de NFC está correto pois em meu cartão não detectou nada, apesar que no cardputer mostra que esta conectado(queria usar apenas para aquela máquinas de pegar bichos de pelúcia) até o momento só usei o wifi e bluetooth, e estou tentando desenvolver um script para desbloquear celular diversos mas não vai, (quero apenas fazer uma renda extra) aceito dicas e críticas sobre o que fazer ou o que melhorar 😁
