I can be more specific.

When I "Download" from UI Flow 2 to the device, it works:

Press BtnA to switch on.
Press BtnA to switch off, once my program allows, with custom MPY:

hold_pin = Pin(46, Pin.OUT)
hold_pin.value(0)

But a problem is if I LONG press (6 secs) BtnA, the device FULLY resets. It goes to the QR code and device Mac screen. That menu crashes almost immediately, meaning I can't rotate the dial to run my Python script. The only way to get it back working is to redownload from UI Flow 2?

Is there a way to turn off that long-press reset function? Or to stop the QR code menu from crashing, so I can at least run my program?

These details about long press BtnA or the reset button on the back don't seem to be covered by the main reference, https://docs.m5stack.com/en/core/M5Dial

@teastain Thanks, but I'm still unclear how to navigate the bootloader on the M5Stack Dial. What I'm used to are ESP32 or Pico devices that are flashed with standard Micropython builds, and start main.py or boot.py on startup.

The firmware on the official Micropython site only support a couple of M5Stack devices and not the Dial. Would the one for the Atom S3 Lite work on the Dial https://micropython.org/download/M5STACK_ATOMS3_LITE/ ?

Otherwise, with the "UI Flow 2" firmware, the M5Stack Dial has its own mysterious bootloader, which allows OTA updates and configuring Wifi etc. On boot, this takes several seconds longer, and starts my Micropython script if connected to USB-C cable. I want this to work just on battery power, so I have connected the Lipo battery to the battery connector on the Dial. If I start the program with USB-C connected, I can then remove the USB-C cable and the program continues fine. I can also use Thonny to start the program, and see the REPL console.

What doesn't work is, with only the battery connected, turning on the device with long-press of the front bezel button (BtnA). After a successful download of my program from UI Flow 2, it's supposed to run my program, but just.. doesn't. The device turns on (red LED on underneath) but nothing on the screen. Pressing reset turns it off (red LED goes off). Pressing BtnA turns it back on again. But it's not running the program I made in UIFlow 2.

Is there a guide somewhere to using a M5Stack device on battery, configuring the bootloader, to make them run a Micropython program on boot? I'd really prefer to get rid of that bootloader - it's not helping me.

I can't figure out what I'm doing wrong, the documentation is fragmented and low on detail, and I haven't found any good guides to programming and using the Dial.

Thanks in advance,

@ajb2k3 That's great to hear that it's an option!

So do you flash your M5Stack device with the M5Burner and UIFlow build, or is there a more "normal" Micropython build that works (the Dial is an ESP-32 S3 "Stamp").

Can you make your M5Stack device run your Micropython code directly, without the bootloader that shows Wifi settings etc?

Any help or tips appreciated.

Is it possible to program the M5Stack Dial directly in Micropython, and have the device load that .py file (e.g. main.py) from boot when connected to battery, without messing around with UIFlow 2?

I'll need access to the M5Stack libraries still, to display things on the screen, make beepboops, read the touchscreen, read BtnA etc..

I'm going in circles. There are many confusing posts from 5-7 years ago. There's a deprecated Github folder that looks promising, but then says to use the new Github for UIFlow 2, with no instructions on how to just do Micropython from Thonny or ideally VSCode, without the buggy graphical UI Flow 2 interface.

I feel this is simple, since all UI Flow 2 is create Micropython code, but I can't quite figure it out?

Many thanks,

Adam

Please, can someone help me? My program runs fine in UI Flow 2 with the big "Play" button, but on "Download" it breaks as below.

This is M5 Stack Dial with UI Flow 2.

How do I resync the project resources properly?

I've tried reloading the browser and reloading my project. The file "RiccyLogoBlack240.png" is not in my project, or on the M5Stack Dial device, and hasn't been for days. That image is not mentioned anywhere in the code (text search shows nothing). I don't even have that image to re-upload anymore. It's not shown in "Project files" on the left. I don't know where it's getting that reference from, and it's stopping me downloading the rest of the program to run on the device?

[INFO] Syncing resources...

@PharkieB My idea, above, works!

Now, I can turn ON my Lipo-powered M5Stack Dial with the "Wake" (front button), it loads my UI Flow program, and then I can tell the software (btn A) to switch it OFF, when that's appropriate:

This is using the "System >> Execute mpy code" block with this for on:

hold_pin = Pin(46, Pin.OUT)
hold_pin.value(1)

and this for off

hold_pin = Pin(46, Pin.OUT)
hold_pin.value(0)

Ideally this would be a standard UI Flow block for the M5Dial (keep device on once awake and on battery). It seems odd I've had to invent it, based on detail in the documentation.

@scoobysnax Wondering if you got any further with this?

I'm also struggling to figure out how to get the M5Stack Dial working with a small Lipo battery. I just want to easily turn it on and off and start the program I made in UI Flow 2 and downloaded to the device. That seems VERY HARD, so far?

As you say, if I connect the battery, then connect USB-C power, the app boots correctly into my app (after a few slightly annoying seconds). Then I can disconnect USB-C power and the app stays working. That's... encouraging?

Without the USB-C cable, I can turn the device ON with long-press of the main fascia button. That's indicated here:

I can turn it OFF with the reset button on the back.

However, "ON" with battery means "load the boot loader thing" rather than "run my app". It shows Wifi settings, "helloworld.py" (which is not my UI Flow program) - then crashes after a few seconds. I managed to set "Boot screen: OFF". So now, instead, when I hold the "Wake" button (main fascia button), it says "Success: 100%" (black on white) turns off the screen, and does nothing else. I can repeat this by pressing Reset then the main button again.

My UI Flow program has "Boot option set to: Run main.py directly" in the Setup part.

The documentation says:

"Wake up can be initiated by pressing the "Wake" button or by an IRQ signal triggered
periodically by the RTC. After triggering the wake-up signal, >> set the HOLD (GPIO46)
pin to a high level (1) during program initialization to maintain the power supply.
Otherwise, the device will enter the sleep state again <<
When there is no USB external power supply, press the RST key to power off. 
Alternatively, when there is no USB external power supply, set HOLD (GPIO46)
to 0 during program operation to achieve power off."

I'm confused by that. Do I need to figure out how to set GPIO46 to high from within UIFlow?

I can confirm the battery connector is JST GH 2 pin 1.25mm: I bought these and they fit perfectly:

Best wishes and hoping someone can help! 🎄

@gordsh That's great, thank you! Is the .F3D file available?

@gordsh I'd be interested in the .f3d file if you ever made one? Unable to find a good, editable model, and wish to make some enclosures or possibly replace some plastic parts with my own.
