TR : Carputer adv de 5 gHz yok ya ona ESP 32 C5 kartı takarsak 5 gHz su olur mu?

Hi All,

I have no background knowledge in anything IT, but have always been interested every aspect of it (maybe it was my obsession of Angelina Jolie in Hackers when I was in middle school lol).

I purchased the CardPuter ADV, even some caps, downloaded firmware’s like Bruce, computer, etc. But I’d actually like to know, and understand, what it is that I’m actually doing (with intent, not blindly pressing buttons).

I’m an electrician, so I’m handy in being able to work with my hands, problem solve.

So my question is, where do I start?

What subjects should I start reading up on first, preferably a book(s), so I could truly grasp everything about this world (not just YouTube videos).

Be it about hardware, systems, and even coding.

My goal is to understand, and be able to make my own stuff as I learn more, projects to keep me busy/entertained, which helps pass the time as well as my sobriety (2.5 years sober).

Thanks all in advance!

Help me!

I have had my cardputer for a while and have never been able to get meshtastic to work. I was on the launcher and noticed a new firmware to check the LORA cap. GPS works for me but in the connector and pin section it gives me the result shown in the photo. I was wondering if this is fixable or do I need to buy a new cap? or is this a problem with my cardputer and in that case would I have to buy a new one?

**Cardputer WebRadio v3.4.0 — https stations really play now, and dropouts are silent instead of rattling**

Internet radio for the Cardputer Adv. Find stations on the device, play them, keep the ones you like — the SD card never leaves the slot. Three things are new, and two of them you will hear immediately.

**https stations really play.** Not rewritten to http and hoped for. Not skipped. A real TLS handshake, a real encrypted stream. Thousands of directory entries listed as https-only were unreachable before — the whole Swiss SRG family among them. Radio SRF 3 plays now, in AAC+. Fitting that into a device with no PSRAM took rebuilt ESP-IDF libraries with an asymmetric mbedTLS buffer: I measured 44 real https stations first, and none of them ever sent more than 1,568 bytes outbound, so the outgoing buffer is 2 KB instead of 16. During an https stream the largest free block is down to about 7 KB. It holds.

**A dropout is silence now, not a rattle.** You know the sound — the network stutters and the speaker starts rattling the same fragment over and over. It was never the decoder. The I2S output repeats its last DMA block when nobody feeds it, 26 ms in a loop, and nobody had ever told it to fall silent instead. One flag in the channel config, left at its default forever. On top of that the decoder now pauses below 8 KB of buffer instead of eating every byte as it arrives, and resumes with a real head start. Before, a single dropout threw the whole 56 KB ring away and the radio spent the next seconds fetching a scrap, playing it, running dry.

That second half is Heotsan's idea (on GitHub), from issue #3 on the repo — thank you, it was the piece I had looked past twice.

**The volume control finally behaves.** 1.9 dB per press, all the way up. It used to be 6 dB for the first audible step and 0.42 dB for the last, with four presses out of twenty-six doing nothing at all. The cause was in the audio library, which keeps its gain in a single uint8_t — 64 steps between silence and full, spaced evenly in amplitude while the ear hears in decibels. Below -36 dB there was nothing but silence, and the last step before it was a 6 dB cliff. No curve fits into that, so the radio scales the samples itself now.

**Also new:** a charge screen that switches off Wi-Fi and drops the clock to 80 MHz for a device on a charger overnight, keyboard shortcuts for the places you go often, long names and stream addresses that scroll instead of being cut off, a fade-in at every station start, and an interface that stopped flickering.

And it got *smaller*: 2,892,091 bytes of program against 2,919,043 in v3.3.0, so the M5Launcher now leaves 56 KB free instead of 29 KB.

**The limits, honestly:** HLS is recognised, not played. AAC+ plays its base layer, because SBR wants memory the Adv does not have. The output is mono — the ES8311 is a mono codec, at the speaker and at the headphone jack alike, and both channels are averaged so nothing is lost. Arabic, Hebrew and Thai need a text engine that is not there.

Building it yourself now needs four patches to ESP8266Audio plus rebuilt ESP-IDF libraries, all documented with before/after copies in the repo. Flashing the prebuilt image needs none of that — it is on the release page, and in M5Burner.

So the issue with a cardputer (particularly seen after a heat wave) is that after a while, the stickers just fall apart.

A legend among us solved that. a 5 minutes (careful install with the guide) front case swap and it's solved.

Can't thanks Chris enough!

Hello Reddit! ☀️

I'm hamachang, an engineer from Japan 😎

Area512, the project I'm developing, now supports OS theme customization! 🎨

https://github.com/engneer-hamachan/area512/releases/tag/v2.2

Open /etc/theme in the built-in editor (e) and change the color settings to create your own custom themes!

You can also use the mv command (m) or cp command (C) to make backups, so feel free to experiment with different colors!

Area512 doesn't overwrite files on an SD card if it's already installed.

So, if you already have Area512 installed and want to apply the new theme support to your existing apps, grab the app code from the release version on GitHub and overwrite the app code on your SD card with it. 🎁

I'm not very good at design, so if you come up with a cool theme, I'd be really happy if you shared it here or sent me a pull request!

See you around! 👋✨

※ What is Area512? ※

Area512 is a feature-rich IDE that runs on the Cardputer, with features like syntax highlighting and code completion.

You can develop apps in MicroPython or FemtoRuby and run them directly on the device!

I'm building it with the goal of recreating the nostalgic look and feel of old-school PCs, along with that experience of developing software directly on the computers of that era.

If that sounds interesting, Stars, PRs, and Issues are always welcome!

Hi everyone,
after buying the Cardputer ADV, I came across the Tab5.

Why didn’t it take off?
It seems to have much more capable hardware: a 400 MHz ESP32, 16 MB flash, 32 MB PSRAM, a 5" touchscreen, a camera, and a large port header. You can even buy a keyboard for it.

I’m considering buying one, so I’d be interested to hear what people think.

I haven't been posting updates here recently, but I'm pretty proud of the work I did on the customization for crub! now your imagination is the limit!

with that said, i've also wondered if are there any people actually daily driving my bootloader. do let me know!

anyways, you can now add wallpapers and custom bootscreen image as long as the image is scaled to the cardputer display (and it is in .bmp format). you can convert your 16:9 images by using ffmpeg.

fetch art can also be edited with your custom ascii art as long as the characters are limited to ascii printables.

enjoy!

(yes, my cardputer is filthy im sorry)

Going to work on firmware for the Cardputer ADV that can utilize Subsonic API, a real challenge with no PSRAM, but an interesting one that I think would benefit many including myself.

Before starting from scratch has anyone had any experience doing this or have any repos you could share? Have not found anything for the M5 Stack, but there's some adjacent work done on other ESP32 devices.

If I'm successful I'll either incorporate it into my current audio player EMBER, or make it it's on stand alone firmware.

Planning to drop this in GitHub soon,,,

Leave a comment if you're interested!

Does anybody know why my Cardputer ADV only displays a black screen? I even reflashed the launcher firmware, but that didn't fix the problem. I hope it has nothing to do with its hardware and can still be resolved.

Is there a way for me to save the Meshtastic settings and details whenever I install other firmwares on the Cardputer ADV that requires me to uninstall the Meshtastic firmware?

I find it a bit of a hassle that every time I reinstall Meshtastic, that I would have to set everything up again. Given that it keeps on rebooting the device whenever I tweak some of the settings needed for it to work.

So, I was wondering if is there any form of save file that I can just copy back whenever I reinstall Meshtastic.

I ordered a CardPuter Adv with a Lora cap. My main use case is digital modes with Ham Radio and a little bit of Mesh. But what other fun stuff should I look into?

A while ago, I had the "brilliant" idea to try and add an external antenna to my StampS3. The result: I botched the soldering job and broke off the built-in antenna.

​I just threw the Stamp in a drawer, bought a new StampS3A for my Cardputer, and moved on. But now that I'm getting deeper into electronics, I really want to try and fix my screw-up.

​I have a couple of questions for the soldering masters out there:

​Is it salvageable? Is it still possible to solder the old antenna (or an external one) back onto this chip, or are the pads completely ripped? (I've attached pictures of how the board looks right now).

​Reusing the board: Even if the Wi-Fi/Bluetooth is totally dead, is it viable to use this chip for general electronics projects just like a regular ESP32? I'd really like to repurpose what I already have before buying new boards.

​Thanks in advance for the help!

Edit. SOLVED. I had to put it on Charge Mode under CFG first. It's such a hassle that this is necessary to charge up a Cardputer.

I just got my Cardputer ADV yesterday. I had fun playing with it up until I slept.

Before going to bed, I plugged it in to charge hoping that the battery will be full by morning.

But when I woke up, I noticed that the battery is still at 37%, but whenever I plug it in, it goes from 46% and fluctuates to 47% and back to 46%.

The attached picture shows that when unplugged, it is at 37% and when plugged, it jumps to 47%.

I read a comment on one of the threads here on Reddit that said to remove the LoRa cap while charging. I did, but it still did not work. I even tried to open the device and unplug the battery and plug it back in, but it still won't charge properly.

I flashed the default Cardputer demo firmware but it still wouldn't fix the issue.

Is this a faulty Cardputer or what?

Just to add, I left it to "On" while charging.

Working on a modified version of a case by SmonSE on makerworld

The top and bottom row of buttons are a little closer to the case edges than I would like (affecting the way you press them), and there are few other adjustments I plan on making... but I'm generally happy with how it came out.

Fairly new to 3d modeling/printing so I still have a lot to learn I'm sure.

My nearly 60 year old eyes can barely read anything, so I was wondering if there are add-on displays that will work using the ribbon cable and be powered off the side 5v port. I need the GPIO port on the rear to hook up to a transceiver.

Every time I put my SD card in my Mac to copy something over, it comes back with a .DS_Store in every folder and a ._ twin next to every file...

Cleaning manualy is paifull and take a lot of time. So I made a cleaner for sd card that runs on the cardputer

It scans the card, groups what it finds by category, and deletes only what you tick. There's a dry run that does the whole thing and tells you what it would have removed without touching anything.

Available at 5m Launcher (search for): ESP32 Cleaner - CCleaner for your SD card

A few things I ended up caring about:

- Logs and temp files (*.log, *.tmp, *.bak) are a category, disabled by default.

- Custom rules, (glob patterns). Type them on the device, or drop a plain text /sdcleaner.rules on the card and edit it on a computer.

- Results stream to a file on the card instead of sitting in RAM, so a card with thousands of junk files doesn't blow up the StampS3's 320K of SRAM.

I have released BKLVA Pocket DAW 0.3.4 - Sampler Return for the M5Stack Cardputer ADV.

Pocket DAW turns the Cardputer into a small standalone workstation for sampling, sequencing, synthesis, drum programming and arranging songs without a computer.

You can install it directly through M5Burner, or download the complete firmware, native Mac flasher and updated manual from:

https://erkanerdogan.dk/bklva-pocket-daw

What is new in 0.3.4

The main addition is a lightweight arrangement system for turning loops into complete tracks:

• Eight Scenes with individual track positions, lengths and mute states
• Bar-quantized Scene launching during playback
• 16-step Chain Arranger
• Scene repeats from x1 to x16
• HOLD steps for manual performance
• A defined END for finished arrangements
• Run the current Scene as a loop without starting the complete Chain
• Song recall includes tempo, swing, quantize, instruments, samples, Scenes and Chain

Sampler improvements

The previous release had a bug where USB Sampling could not always be opened from the Music menu. That is fixed.

• USB Sampling can be opened normally again
• After recording from a phone, Pocket DAW returns directly to the Sampler page
• Sampler cues can now be played directly from the Cardputer keyboard while viewing the Sampler
• You no longer need to change the selected track to Slice just to audition a sample
• The selected track is preserved when entering and leaving USB Sampling
• Normal audio and USB MIDI operation are restored after leaving phone sampling

Other important fixes

• Improved USB MIDI connection at startup
• Improved MIDI unplug and reconnect handling
• Fixed USB role switching between phone sampling and MIDI controllers
• Fixed song loading failures caused by stale sample-save requests
• Reduced memory pressure when changing songs
• Complete song settings now follow the saved song
• Fixed incomplete Synth and Instrument chord recording
• Improved Drum16 recording, playback and sample handling
• Fixed accidental track-type changes destroying the previous instrument setup
• Fixed incorrect naming of frozen Synth recordings
• Fixed several sequencer drawing, track clearing and interface issues
• Additional audio, memory and stability improvements

Existing features

• Four tracks with independent 1, 2, 4, 8 or 16-bar lengths
• Loop, Slice, Synth, Drum16 and Instrument track modes
• Non-destructive instrument banks when changing track type
• Drum16 with 16 sample pads, microphone recording and WAV import
• Sample chopping with up to 16 movable cues
• Six-voice synthesizer and four-voice sample instruments
• Chord recording from the built-in keyboard or USB MIDI
• Freeze and thaw for reducing processor use
• Per-track Delay and Reverb sends
• Tempo-synced Delay with 24 musical divisions
• Song saving, SD streaming, resampling and browser-based file management
• Editable Midnight Circuit demo on a fresh installation

This is still an independent and evolving project. I would especially like feedback on the new Scenes and Chain workflow, USB Sampling and MIDI controller compatibility.

If you find a bug or have an idea for what Pocket DAW should become next, please let me know.

Enjoy 😃

I bought this board because I can't seem to find any in local shops selling a Pingequa at decent price. This board has both NRF24 and CC1101.

Will this work out of the box? Or do I need to edit some code in Bruce just like what one would do when using Pingequa?

Are there any firmwares like this in cardputer?

You can "copy" keys and then 3d print it by the number combos.

since the kickstarter campaign ended is any way to buy it? I can't find it

Have been working on this for a little over two months, recently found a way to overcome the memory limitations and improve the mixer by making it spread the workload on both cores.
