The M5Burner DBus error when publishing a BIN file usually indicates a permissions or communication issue between the app and system services. To fix it, try running M5Burner as administrator (or with sudo on Linux), ensure DBus is properly installed, and check USB device access permissions on your system.

@felmue I was struggling to figure out why my FIRE was restarting each time I tried to use the UART port... Using Port B worked though.

Thanks for the suggestion!

@I_am_Exiled When I get situations lie that I just use M5 Burner to erase and start over

@shiva said in Problem with button input during loop. (interupt loop):

Hello,

I have developed a productivity timer application and am encountering two issues related to interrupting a loop that includes a sleep operation.

Interrupt Timing: Currently, to interrupt the loop using a button press, the button must be triggered at the precise moment the event occurs within the loop. This makes it very difficult to reliably interrupt the loop as intended.
Label Update After Interruption: When the loop is successfully paused, a display label (label 0) still updates once more with a lower value before halting, which is unintended.
Could you please advise how I might improve the code to:

Allow the loop to be interrupted at any time, rather than requiring precise timing, and
Prevent the label from updating after the interruption is triggered?
Thank you in advance for your assistance.

Thank you, this is what I am looking for. Do you have a link to the documentation for Timer? I want to create a countdown timer.

@nabstar Did you ever find a solution for this? I’m having a similar problem

Hi Liquidbeam,

I know it has been a long time since you posted this, and I am curious if you ever got it to work. While I have worked with M5Stack (Blockly) for years. I know I can help you with the other aspects of your desired application and am more than willing to assist. This however is my first experience with BLE device scanning.

I copied your code into my CoreS3 with UIFLOW2 V2.2.4, and I can't even replicate what you have done.

I would very much appreciate an update on your experience.

Thank you

try reflash factory firmware
https://docs.m5stack.com/zh_CN/guide/restore_factory/m5stickc_plus

Update your system and install the latest version of UIFlow or M5Burner if they are not running on Windows 10. Ensure that the CP210x USB to UART drivers have been installed. Ensure that the software is run as an Administrator and that conflicting applications using the COM port are closed. Disable your antivirus/firewall temporarily and reinstall the software if necessary. As a result of these steps, connectivity and execution issues can be resolved, ensuring that M5Stack tools operate smoothly.

@krumme2990
You mean Emulator?
No there is not.

@robski Thanks, I figured it out.

@felmue
Hello, I'm going to tell you everything I know and have tried so far.
I'm experiencing an issue with my M5 Hard devices. A few months ago, I purchased a couple of M5 Hard units for an MQTT data transmission project. I developed it in UIFlow 2, and everything worked perfectly.

Recently, I bought more M5 Hard devices to expand the project, but now I’m facing a problem: when I install the firmware and try to connect them to WiFi, they won’t connect. I have tried the following without success:

Reinstalling the USB drivers on my computer.
Resetting the device to factory settings.
Reinstalling the firmware.
Trying different WiFi networks.
Temporarily disabling the firewall and antivirus.
Using different firmware versions.
Checking the router configuration and connection parameters.
Despite all these attempts, I still cannot connect them to WiFi. I’m getting the following error:

arduino
Copiar
Editar
E (328401) wifi: sta is connecting, return error
Traceback (most recent call last):
File "<stdin>", line 19, in <module>
File "<stdin>", line 12, in setup
OSError: Wifi Internal Error
Additionally, I’m also getting this error:

nginx
Copiar
Editar
E (328338) i2c: i2c driver install error
I don’t believe this is a network issue (firewall, antivirus, etc.) because, as I mentioned earlier, I have successfully programmed and connected other devices without any issues.

I would really appreciate any suggestions or help.

My Bad... I like to clear some mistake of my post.

Excuse for my bad english. What I'm saying is when I use python code like "wifi.connect(SSID, PW)". It will fail , unless reflash configurate setting with M5Burner to the same SSID and Password setting as code.

vlw font work perfectly when I change the code from "Buf=M5.Lcd.newCanvas(130,50,1,True)" to "Buf=M5.Lcd.newCanvas(130,50,16,True)". I think this might support 16bit sprite only.

That only happen when I use the second UART in M5StickC (although this could be done in UIFLOW1.0).

@laneishere1655 @Jdo300
UiFlow have no and will no support for microphone. Please transfer to UiFlow2

Here is how I solved this:

@ViperNZ Take it back to the basics of just a label, test and then add each block untill the error happens and then post the error message from the console.

@ajb2k3 That all makes sense to me.

Sorry for the confusion, I'm trying to use either the mechanical limit switch OR the ir photogate as a limit switch. Not trying to use both at the same time. But I was unable to use either module using the corresponding UIFlow module integration. I'll post an example next week which hasn't worked for me so far.

Yea, I originally had it in port A but moved it over after confirming there wasn't a negative impact as it's a bit cleaner with both plugs on the same side of the device. If you said there was an electrical difference that could be causing the non-zero reset bug I could try port A again. Any ideas there? Should I be using a different reset / get function? How can I debug this issue better?

Seems pretty clear cut when I'm setting the rotary_value to 0 but when I get the rotary value, it's not 0. It resets to the initial value, which is often not 0. Today I recall three reboots which all had different reset values, roughly 636, -1035, -1.

-1 was close enough and worked for me, but when I got the other values I just reset the board and basically got it to choose a new "0" value.

@ajb2k3 Actually, “concat” is a widely recognized and valid term in programming that refers to combining two or more strings. There’s no need to be condescending to a fellow programmer by telling them to “use his language.” He's used English in understandable manner.

Are you able to share your .m5f2 file to there?
