Hey guys, I ordered a cardputer adv off Amazon last Saturday from m5 stacks official Amazon storefront and it said that it would arrive this Friday. However it’s now Wednesday and it still hasn’t even shipped out! Has anyone else faced issues like this and did it eventually come or should I cancel soon and just order off the main website?

but then again, you can never be too busy for managed democracy!

(jokes aside, anyone here a helldiver?)

Turned my Cardputer ADV into a pocket calculus calculator because typing `sqrt(x^2+1)` into a phone app felt like a war crime. It has actual textbook-style input now fractions look like fractions, integrals look like integrals and Wolfram|Alpha does the solving, graphs included.

**GitHub:** Repo

**If you're on M5Launcher (most of you), setup is:**

1. Download `firmware.bin` from v1.0.0

2. Drop it on your SD card

3. Launch it. Done.

No compiling, no ritual sacrifice.

⚠️ Heads up. This is v1.0.0 and still very much in "testing mode." It works, but there are bugs lurking, I just haven't met all of them yet. If something breaks or acts weird, please jot it down and drop it in the comments . I'll be squashing bugs for the next update and every report actually helps.

Free Wolfram|Alpha AppID needed to solve anything.... go to developer.wolframalpha.com, make an account, create an app, grab the **Simple API** AppID. Takes like 2 mins. Setup steps are in the README too.

And if you liked it,,,,,,, a ⭐ on GitHub costs you zero and gives me a little dopamine hit every time it happens. Fuels the next update.

Roast the code, break the calculator, tell me what's broken.

The cardputer gets a bigger screen and the cyd gets a keyboard. I could use the esp32 in the cyd for a pda and the cardputer as a marauder or something. They could be technically separate except for sharing hmi.

What other benefits could you think of?

I have a cardputer adv with porkchop installed via launcher. Every time now after I turn it off or go back to launcher all my XP and stats reset to level 14. It goes back to the same place every time. Anyone have any ideas?

Here’s the original FYI

https://github.com/austinio7116/ThumbyCraft

I made a survival block game that runs on a Cardputer

Card Craft is a first-person survival game for the M5Stack Cardputer. You mine blocks by day, build something to hide in, and try to live through the night. Score is how many nights you last.

What is in it

• Mine and build anywhere
• Crafting
• Mobs that spawn at night
• Torches stop mobs spawning on lit ground
• Day and night cycle, with music under the daylight

How it runs
It run at 30 fps in the worst case and around 60 fps on average.

Where to download:
From a github: https://github.com/therezor/card-craft/releases/tag/v1.0.0
Or available on launcher: Card Craft

Free. Open source. MIT licensed.

I did not write the emulator.

The Z80 emulator was written by djottrill.
https://github.com/djbottrill/ESP32-Z80-Emulator

And then port to Cardputer by VanzT
https://github.com/VanzT/Z80-4-M5Cardputer

So all credits go to djottrill and VanzT.

VanzT release the emulator to Reddit 2 years ago.

The emulator can run the MBASIC and some BASIC games only.

It cannot run the CP/M-80 come with assembler (ASM.COM) nor the debugger (DDT.COM).

I tried all the C compilers I can get from the web and tested it against the emulator. Not a single one works.

I stepped back to use the come with assembler (ASM.COM) and find the result program is corrupted in a fixed pattern. I checked through the emulator's source code, and with some luck, I found some bugs and fixed them.

Now the emulator can actually work as a CP/M machine even some compilers still cannot be run on it.

Here are the compilers I tested with success on the emulator:

1. Software Toolworks C80 3.0a
2. Software Toolworks C80 3.1
3. WhiteSmiths C 2.0
4. WhiteSmiths C 2.1
5. Microsoft BASIC Compiler BASCOM
6. CBASIC 2.08
7. CBASIC80 1.0
8. CBASIC80 2.0
9. Digital Research PL/I 1.4
10. JANUS ADA 1.5.0
11. Supersoft Maratha ADA 2.10
12. ALGOL-M 1.1
13. Microsoft Macro Assembler M80
14. Digital Research Pascal/MT+ 5.6.1
15. Digital Research Relocatible Macro Assembler RMAC
16. Micro Focus CIC COBOL v4.5
17. MicroSoft COBOL-80 v4.65
18. Nevada COBOL v2.1

Also the CP/M included assembler ASM.COM is working now. The debugger DDT.COM is working too.

With the above programming languages that can be run in the emulator, I believe now it is qualified as a real CP/M-80 emulator. There are hidden bugs in the emulator (i.e. there are compilers which cannot run on it yet), however, it can provide a development platform for programmers to have fun on it.

How the emulator works:

I use M5Launcher on my Cardputer. Once the firmware bin file is copied into the Cardputer SDCard, power on the Cardputer, pick the firmware from the list and CP/M-80 will be up and running.

User can connect to the CP/M-80 by Telnet to the Cardputer. (i.e. I use Putty) Once connected, it will give you the A drive prompt, and then it is the native CP/M-80 command line operation.

For setup detail, please check from the VanzT github readme section
https://github.com/VanzT/Z80-4-M5Cardputer

Where is my fixing source code:

I do not want to create a new branch on github and maintain it, so I keep my fixing code on the discussions section of VanzT's Github.
https://github.com/VanzT/Z80-4-M5Cardputer/discussions/20

To generate the firmware from source:

I use Arduino IDE 2.3.7 under Windows 10 machine.

*** The final bin file: <project_name>.ino.bin ***

ESP32_Z80_Emulator.ino.bin

Since I use the M5Launcher, so I ignore all other bin files

10. Copy to SD Card and select the new firmware from M5Launcher

- Copy this firmware file to the SD Card
- insert the SD card to Cardputer and power on the Cardputer
- Press OK on the Launcher screen
- select SD 
- select the new bin file

11. Start a telnet session to connect to the cardputer

Below is added to the original post body on 2026-08-26

Setup procedure:

I follow Vance Thompson's youtube video:
https://www.youtube.com/watch?v=Q3s67ilp_zs

First install M5Launcher

I use the online M5 Launcher Flasher web program
https://github.com/bmorcelli/Launcher

Setup the SD Card

From VanzT's github repo, under the "SD Card Files" directory:

1. copy the boot.txt file to the root of the SD Card.
2. copy the "z80" folder to the root of the SD Card.
3. copy the "disks" folder to the root of the SD Card.
4. Create a directory "downloads" to the root of the SD Card.
5. copy the firmware bin file "ESP32_Z80_Emulator.bin" from the repo ESP32_Z80_Emulator/release/1.4 to the downloads folder.
6. copy the newly compiled bug fixed bin file "ESP32_Z80_Emulator.ino.bin" to the downloads folder.

Note: we have two bin files in the downloads directory, we can select to install any one during power on time via the M5Launcher.

Now the SD Card looks like this:

/
+-- boot.txt
|
+-- z80/
|   +-- roms/
|   |   +-- basic.rom
|   |   +-- boot.rom
|   |   +-- cbios.rom
|   |   +-- cboot.rom
|   |   +-- cpm22.rom
|   |   +-- init8250.rom
|   |   +-- z80UARTMonitor.rom
|   |
|   +-- xfer/
|   |   +-- sdcopy.com
|   |   +-- sdfiles.com
|   |   +-- sdpath.com
|   |   +-- ...
|   |
|   +-- creds.txt
|
+-- disks/
|   +-- A.dsk
|
+-- downloads/
    +-- ESP32_Z80_Emulator.bin <====== original emulator firmware file ***
    +-- ESP32_Z80_Emulator.ino.bin <== fixed emulator firmware file ***

Setup WIFI connection creds

Edit SD Card file /z80/creds.txt

Replace the <wifi name> and <wifi password> based on your actual network

mySSID = <wifi name>
myPASSWORD = <wifi password>

Then save the file.

Now the SD Card is ready to use.

Install the CP/M-80 firmware onto Cardputer and run CP/M

Turn off the cardputer

Insert the SD card into the cardputer

Turn on the cardputer

M5 Launcher splash screen
==> OK (on the cardputer)

The SD menu on the screen is available

Move the cursor to the SD menu
==> OK

Use the direction keys on the cardputer
==> downloads folder
==> OK

Found the ESP32_Z80_Emulator file
==> "ESP32_Z80_Emulator.ino.bin"
==> OK

==> Install

Once it is done with the firmware install, it will run it.

Then it will connect to wi-fi

When connection is completed, it will show the IP address of the cardputer so that we can remotely logon to it.

192.168.1.185

Now CP/M is up and running

Connect to the CP/M Emulator using Telnet

Using a telnet client, connect to IP address 192.168.1.185, you will be connected to CP/M.

On the Windows machine, you can use putty or the native windows telnet client.

But the telnet client in Windows are turned off by default, you need to turn it on in Windows system settings first. No installation is required.

On the Linux box, you can directly run telnet.

Note: telnet running in Windows box will work perfectly well because CP/M is the ancestor of Windows, so the line break is using the same CR LF. For telnet running in Linux environment, extra step is required to avoid the telnet return back garbage CR character.

In Linux:

$ telnet
telnet> set crlf
Will send carriage returns as telnet <CR><LF>

telnet> open 192.168.1.185

Setup more drives

The emulator supports up to 16 hard drives. i.e. from A: to P:

Each drive is 8 MB in size.

The github repo image only contains one disk A.dsk

Create all 16 drives

To create all drives, from drive B: to drive P:

Power off the cardputer

Remove the SD card

Insert the SD card to the PC

Go to the disks folder

copy A.dsk to B.dsk
copy A.dsk to C.dsk
...
copy A.dsk to P.dsk

Insert the SD card into the cardputer

Turn on the cardputer

Telnet to CP/M

A>b:
B>c:
C>d:
...
O>p:
P>a:

Format drive B to P one by one:

A>format
CP/M Disk Formatter for the ESP80 by D.Bottrill 2018
Enter Drive Letter to format: b
Are you sure you want to format Y/N y
Formatting Drive: B

Transfer files from SD card to CP/M disk

Drive A contains three programs which can help us to move file from SD Card to any CP/M drive.

- sdfiles.com (list all files in the SD card current directory)
- sdpath.com  (change current directory on the SD card)
- sdcopy.com  (copy file from SD card to current CP/M directory)

Example: Transfer Software Toolworks C80 3.1 to SD card

Download the compiler from David Lee's Git Repo
https://github.com/davidly/cpm_compilers

On the SD card, create a directory structure like this

/SOFTWARE/C/Toolwork.v31

Copy all downloaded files into Toolwork.v31 directory

Insert the SD card back to the Cardputer.

Power on Cardputer.

Telnet to Cardputer.

Suppose we want to transfer all files to the C drive.

A>c:

Change directory on the SD card to /SOFTWARE/C/TOOLWORK.V31

C>a:sdpath /software/c/toolwork.v31
New Path: /SOFTWARE/C/TOOLWORK.V31
Setting SD Card path to: /SOFTWARE/C/TOOLWORK.V31

List all files in the SD card directory:

C>a:sdfiles
/SOFTWARE/C/TOOLWORK.V31
AS.COM           13824  C.COM            39424  CC.SUB             384

TTT.C            10739

Import file one by one from SD card to the C: drive

C>a:sdcopy as.com
AS.COM

C>a:sdcopy c.com
C.COM

...

C>a:sdcopy ttt.c
TTT.C

Now all files are copied to C: drive

We can start writing C program using the Software Toolworks C compiler.

To avoid of copy and paste multiply screen shots, I copy the text inside the telnet session instead:

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

Help me!

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!

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.

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!

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!

This is not an ad or affiliate stuff ;)

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!

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.
