お世話になります。

現在、M5Stack FIRE に関して次の2つのバージョンがあります。
　　1) V2.6 (USBチップ: CH9102F) ※BALA2 FIREとして購入したもの
　　2) V2.7 (USBチップ: CH9102F)
2)のV2.7については、Windows11(24H2)で問題なくUSBシリアルポート接続
認識ができていますが、同一環境(PC環境、USB接続環境、USBケーブル等)
で、1)のV2.6について、デバイスマネージャでCOMポートとして認識できず
困っています。

様々なUSB環境(ハブ、ケーブル等)で試していますが、一瞬接続できたことも
過去にありましたが、現状は、ことごとく正しく認識されません。

もし、同様のトラブルに遭遇された方で、アドバイスなどがございましたら
よろしくお願いします。

Burn of UIFlow2 (v2.2.4-16MB) to M5Core-Grey using M5Burner loads stub but not full firmware. Burn of UIFlow_M5GO (same M5Burner) works fine. The UIFlow2 burn results in inoperable M5GO even though final message says 'Burn Successfully, click here to return'.

Here is screen shot of output from Burn:

Problem:

Der Schrittmotor funktioniert nur korrekt in der Z-Achse bei normalen (langsamen) Drehgeschwindigkeiten.
Beim Versuch, die X- und Y-Achsen zu verwenden, funktioniert der Motor nur, wenn ich die Vorschubgeschwindigkeiten auf das 10-fache oder höher erhöhe.
Wenn ich versuche, die Adresse auf 0x71 zu ändern, wird das Modul nicht erkannt.

Hi, some suggestions for the next hw iteration:
connect imu irq pin connect rtc irq pin to esp32 to let us know whether the irq comes from power button or rtc let the buttons go out the case for easier access reduce time of power on btn to a single click seperate LED and IR for incognito use add the L-R-Center button from the M5Paper

Hello @ckuehnel

Without opening M5CoreInk you probably cannot measure battery voltage with a multimeter. However you can use GPIO35 to read the battery voltage. Check out float getBatVoltage() here.

BTW: I've opened my M5CoreInk today and added some photos to my page (link below). Measuring power consumption in light sleep, deep sleep and shutdown will be next.

Cheers

I stumbled on this restriction again, and dug a bit deeper in the issue.
It appears that the hardware is not limiting the baudrate, but the M5Stack library. More specifically, M5.begin();
Luckily, you can skip the UART init, and do it yourself like this:

M5.begin(true,true,false);
Serial.begin(2000000);
Serial.flush();

And now it works for 2000000 baud.

Hello @AndyT

hmm, strange, if anything I'd expected the M5Stack Gray to work with low brightness level and the M5Stack Black to not behave due to the fact that the M5Stack Gray has additional hardware (e.g. IMU) consuming power to keep the device powered on.

That said, I suspect the IP5306 switching off due to too light load. Try to add the following statement before going into deep sleep. It should prevent the IP5306 from shutting down under light load.
M5.Power.setPowerBoostKeepOn(true);
Happy Stacking!

@sparkinman

Check that:

You have added the M5Core2 library and are doing #include <M5Core2.h> and not using M5Stack.h. Until they merge it my Pull Request and release a new version, my version is more like it will be, better documented and has graphical buttons. (Simply clone it or get the zip file and unpack so that M5Core2 is a subdir of your Arduino libraries dir.)

In Arduino Preferences, you have added https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json as an "Additional Board Manager URL"

Make sure you then select M5Stack-core2 from the "Tools / Board / M5Stack-Arduino" menu.

If this is all good, then you should be able to run one of the examples from the "File / Examples / M5Core2" menu.

Hello @veryalien

Sorry to hear about your troubles.

I looked into the factory test program today and got it to compile and running after enabling PSRAM, the above mentioned fix in SetLDOVoltage() and some cleanup of the old Wire vs Wire1 fight that seems to come back every now and then. I wished the developers could make up their mind and always use Wire for internal I2C devices. Oh well.

The factory test code does something interesting regarding vibration motor voltage. During the startup sequence it is first set to 2 volts, then the motor is quickly turned on and off again and then later on it is set to 3.3 volts (not sure why though). When testing the vibration motor from within the settings menu the latter voltage is used.

it's a library to control a sensor, I had already built my custom blocks that worked with that library, but when I updated everything I was unable to make it go.
so do I have to import the library into the / flash root?

and then?

Hi @m5stack

you could pip install a pyserial module to solve it.

I tried that but the problem persists. As a quick fix, I just flashed it using a window virtual machine.

the LED always RED? which program are you use?

Yes, but after I flashed the new firmware everything is behaving well.

which program are you use?

It turned RED, after I tried to flash it with the newer esptool (2.8) as I showed in my initial topic

we will fix this bug in next version.

🤞🏻

Have a nice day

@robalstona excellent. Thank you for the clarification. It’s logical, and I agree that I don’t require anything higher, but I wanted to make sure for safety’s sake.
