Too low resolution :(

Charging Tab 5 in sleep mode?

@felmue Yeah, seems to be correct. Thanks.

Tab5 LoRa

pjoart — Fri, 23 Jan 2026 21:08:59 GMT

Hi its been a while so just checking in on the development of the stamp module to use LoRa on the tab5, this is a big item for me and a lot is riding on the implementation so any info on release dates is appreciated.

Tab5 RTC backup battery specifications

easytarget — Wed, 21 Jan 2026 18:36:34 GMT

Like @felmue I also did a bit more testing of the low voltage flags, then enabled the charge circuit (and setting the charge voltage via bfvsel to unlimited). The clock has held time ever since.

I'm curious about how long the capacitor can run the clock when fully charged and I have disabled charging again. But my device spends most of it's time on USB power so the duration is hard to measure; so lets try to estimate it :-)

If the frequency out and I2C is disabled (inien = True) the device should typically draw 0.3 µA when on backup battery (table 5 in the datasheet).
The capacitor is possibly a ML414H; 0.07 F.
Table 3 in the datasheet says that the clock oscillator minimum voltage is 1.1v, and the start voltage is VStandby; 3.3v. So we just need to work out the discharge time.

Start with working out the equivalent resistance at 3.3v; R=Voltage/Current = 3.3/0.0000003 = 11000000 = 11 MΩ

Now use an online discharge calculator to do the 'heavy lifting'...
https://3roam.com/capacitor-discharge-time-calculator/
(I like that site; it shows the maths used)

This gives an estimated! time of 845932 seconds; which is ~235 hours, almost ten days. Which seems reasonable for a capacitor backup.

Chain Blank Proto use cases

veryalien — Thu, 15 Jan 2026 16:09:45 GMT

I really can't see the point of the chain proto as it is now.
It just gives electrical connections to the chain bus. There isn't a direct way to create your own chain devices, maybe something with a different encoder or multiple switches, and add your own extensions to the bus protocol to read or write any information.
The example on the product page just shows a simple pushbutton connected electrically to an LED, which lights when the button is pressed. That has nothing to do with chain devices on a chain bus.
You could do that with a breadboard circuit powered over the chain bus pins.
Are there really any useful things you can do with the chain proto as it is, as a 'dumb' electrical connector? Any ideas?
In my opinion, a proto board on top of a programmable(!) STM32G031G8U6 connected to the chain bus would be much more useful to integrate with other chain devices. Of course, you'd have to somehow program the STM32 processor with your own firmware and also write chain bus protocol extensions to read/write data to/from it. Might be a nice project!
But that is what I was really expecting from the chain proto.
Any comments?

ENV Monitor ADV

nunoluna — Sun, 11 Jan 2026 19:14:53 GMT

Hi, @aliense44. I have a Card Computer ADV, a GPS/LoRa module, and an ENV III Sensor. I was trying to test the ENV Monitor ADV app, but it didn't display any information. Could you tell me how to connect it for it to work with the app? Thank you.

M5Dial V1 (not V1.1) BtnA not responding (too low of priority?)

bschwahn — Sun, 11 Jan 2026 15:09:55 GMT

Greetings,

Background:

using M5Dial V1.0 because they are on sale for less than $23 USD (I know slow processor)
using UIFLOW2 because I am new to the M5Stack and don't know python yet
creating a thermostat using the EVNIII sensor
using v2.3.9 of firmware (because v2.4.0 has a bug in my experiences with ESP-NOW)

Problem:

pressing the built-in button on the ring (BtnA) will sometimes "function"
pressing the software buttons will respond quickly without problem
if I remove the "DisplaySensorValues" call then BtnA works expected

What I think is the problem:

it seems that the software buttons from UIFLOW2 has a higher priority than hardware BtnA
this problem does not exist with the newer M5Dial V1.1 with a faster processor

Thoughts:

am I missing something easy?
is there a way to make the BtnA "faster"

Workarounds:

I will look at not updating the display as often by adding a delay by counting ticks
upgrade to the M5Dial V1.1 (ugh, I need 5 more so not the best solution)

Thanks-Brian

Tab5 error in schematic? or in block diagrams? Camera MCLK is not connected?

easytarget — Mon, 29 Dec 2025 09:02:32 GMT

@felmue Thank you for doing the test :-)

I guess this simplifies things for anybody writing a driver; but does prevent people having fun-and-games with under/over clocking the camera module.

I think it also means you cannot 'stop' the camera, which may be problem for extreme power saving. But I suspect the reset pin can be used to halt the module too.

How to scale a bitmap drawn with M5.Display.drawBitmap() on M5Stack?

Morle — Sun, 21 Dec 2025 11:29:39 GMT

I am working with an M5Stack Core S3 using the library. I successfully display a 32×32 bitmap stored as a uint16_t array (RGB565 format) using M5.Display.drawBitmap() (see my code below). The bitmap represents a small animal, but at its native resolution it appears too small on the display (see the result below). At the moment, M5.Display.drawBitmap() draws the image at a 1:1 pixel ratio, and I don’t see an obvious way to apply scaling. How to scale the image by an integer factor (for example, 2 or 3) so that it appears larger on the display?

My result:

My main.cpp code:

#include 

constexpr int IMG_W = 32;
constexpr int IMG_H = 32;

const uint16_t myBitmap[IMG_W * IMG_H] = {
0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000,

PaperS3 anyone got the touchscreen to be more sensitive?

windoze007 — Sat, 20 Dec 2025 11:57:35 GMT

So it looks like the GT911 can have configurable sensitivity either by adjusting the sensitivity threshold or adjusting the gain.

I tried both, however they mainly seem to make it not work

I edited Touch_GT911.cpp:

constexpr uint16_t REG_CONFIG_START = 0x8047;
constexpr size_t CONFIG_LEN = 0x80FF - REG_CONFIG_START;
constexpr size_t TOUCH_SENS_OFF = 0x8053 - REG_CONFIG_START;
constexpr size_t RELEASE_SENS_OFF = 0x8054 - REG_CONFIG_START;
constexpr size_t DAC_GAIN_OFF = 0x806B - REG_CONFIG_START;
constexpr size_t PGA_GAIN_OFF = 0x806C - REG_CONFIG_START;

std::array datas;

// get config
datas[0] = 0x80;
datas[1] = 0x47;
_writeReadBytes(datas.data(), 2, datas.data() + 2, CONFIG_LEN);

// try to change settings - none of these seem to work
datas[2 + TOUCH_SENS_OFF] -= 5;
datas[2 + RELEASE_SENS_OFF] -= 5;
datas[2 + DAC_GAIN_OFF] = 0x00;

// put config
datas[2 + CONFIG_LEN] = 1 + (~std::accumulate(datas.begin() + 2, datas.end() - 2, 0));
datas[2 + CONFIG_LEN + 1] = 0x01;
_writeBytes(datas.data(), datas.size());

Tab 5, how to enable Lora?

HappyUser — Tue, 16 Dec 2025 20:47:22 GMT

@easytarget thank you. That is indeed an option. In my experience not to much work to get a Lora module working. We have a number of them in the field. But we would like the tab5 not become thicker as it is. We are now considering to place an Heltec Lora inside. Maybe that could work. Regards.

Tab5: disable speaker when headphones are plugged in

milaidin — Thu, 11 Dec 2025 08:39:19 GMT

Thank you!
I was not precise enough in my earlier post:
I had already found the code to detect the connected headphones, the part that I was missing was how to turn off the speaker as soon as the headphones are detected (and if it was possible to turn it off independently from the speaker).

Thanks to your comment and some poking around on GitHub I realized that I overlooked the GPIO extension. There is a SPK_EN pin there (Pin 1 on the first extension) that connects to the onboard amplifier and, according to its datasheet, can be used to turn the amplifier off.

Since the headphones are not connected to the amplifier, this should mute the speaker without influencing the headphones - I haven't tried it yet, but that's my guess based on the schematics.

Re: Bluetooth Serial for Tab5

Hey Morten, I’ve had the same issue. The Tab5’s wireless coprocessor makes standard ESP32 Bluetooth examples tricky. A wrapper or checking the dev guide might be the best solution.

Bluetooth Serial for Tab5

easytarget — Tue, 02 Dec 2025 09:53:52 GMT

Hi @MortenComadan ; you don't mention what your project is based on for code; Arduino/ESP-IDF/MicroPython/UFlow2 etc..

For the tools where Expressif have got involved the support should be there already. The C6 co-processor gets a standard firmware (that talks via QSPI to the P4) and the P4 IDF libraries know how to use this.

What I'm unsure about is exactly which features are actually implemented in the ESP IDF; I want to use bluetooth audio sink features.. eventually.

If (like me) you are into MicroPython then good news. V1.27.0 was released a couple of days ago and has official P4 support: https://github.com/micropython/micropython/releases/tag/v1.27.0

UFlow2 is based on an older micropython version; I'm not sure how much of the P4 stuff they may have backported.

I only got my Tab5 today, I'm going to be installing micropython 1.27 asap.

CardputerADV Audio

Scuttle — Sat, 29 Nov 2025 21:15:55 GMT

My CardputerADV was working normally, the audio was ok last night when I was using it. Today I have no sound, I've tried different things with no luck. Any ideas on what might have happened to my board?

AirQ eazydata

robski — Sat, 15 Nov 2025 20:19:10 GMT

could someone confirm that AirQ user demo ezdata works. It was ok for me till end of august (last log) but now looks like it isn't logging, StamPLC ezdata acess is fine just AirQ I have issue with.

https://airq.m5stack.com/48CAxxxxx no logs
https://ezdata-stamplc.m5stack.com/d4dbxxxxxx works ok

AirQuality v1.1 restarts roughly every minute

robski — Sun, 09 Nov 2025 18:36:41 GMT

you can disable sound and adjust timer, 60s for reset is default it does flash black like many ink displays

M5Stamp PLC Controller with M5StampS3 cannot write and read current Date and Time

MCU1536 — Fri, 07 Nov 2025 08:40:57 GMT

Hello felmue,

When PLC was disconnected the power supply.
time.tm_wday cannot remember. Other are correct.

But PLC got the power supply.
It worked normally as below code.

char Text[100];
static struct tm time;
char DayOfWeek[7][10] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
char MonthOfYear[12][4] = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"};

sprintf(Text, "%s, %d %s %d %02d:%02d:%02d",
DayOfWeek[time.tm_wday],
time.tm_mday,
MonthOfYear[time.tm_mon],
time.tm_year + 1902,
time.tm_hour,
time.tm_min,
time.tm_sec);

Serial.print(Text);

Result

[LLM-8850] Is there something wrong in axcl_demo with depth-Anything ?

phillipsback — Thu, 06 Nov 2025 03:28:35 GMT

There something interesting.

DepthAnything can be done with THIS

In OpenAI API, I think Mr. uzuki_aoba already post in Qiita. In the CMD that renew the model list got some TYPO "sudo systemctrl restart llm-openai-api"

I try LLM(qwen3), Whisper(CN), MeloTTS(CN), VLM(InternVL), they are work great with StackFlow that I can call by another computer in my house. But I think it something funny when I install llm-model-internVL. In apt I called is internvl____axcl, but after install the folder name came to internvl____AX650. (In the end, I change the folder name manually...)

BugC2_Slave WiFi Default Password

DavidGuidos — Fri, 31 Oct 2025 19:10:07 GMT

Just received the BugC2 and the M5StickCPlus2 is programmed with a demo program that starts a WiFi server with the name BugC2_slave. Unfortunately it requires a password for me to connect to it. I’m guessing it provides some cool functionality when I connect with a browser. Does anyone know the default password? Can’t find it anywhere. Thanks.

Getting a battery to work to power an M5 Tough?

LukeMathew456 — Thu, 23 Oct 2025 10:00:08 GMT

It sounds like the M5 Tough’s battery issues were likely caused by a polarity or connector mismatch—there’s no strict standard for that battery plug, so reversing positive and negative can easily overheat or damage the board. Before powering up again, double-check the connector pinout with a multimeter, ensure your LiPo has proper protection circuitry and matches the expected 3.7–4.2 V range, and avoid using USB and battery power simultaneously until you confirm how the board switches between them. A proper match should let the Tough run smoothly on battery without overheating or shutting down.
