@amdiaz1065391 do you have M5Burner installed? Is your M5StickC+ comport being detected when connecting to usb?

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.

An M5Burner DBus error may occur when publishing a BIN file due to permission issues, missing dependencies, or port conflicts. Ensure there is no other application using the same serial port and run M5Burner as an administrator, restart the DBus service, and ensure M5Burner is running as an administrator. Reinstall M5Burner, update dependencies and ensure that the USB cable or port is not faulty if the issue persists.

You mean Emulator?
No there is not.

@robski Thanks, I figured it out.

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.

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

the web terminal in UiFlow2 dosen't work for you?

To remove labels and touch buttons, access the interface design or software settings. Locate the labels and buttons section, and delete or disable them. Save changes. Refer to user manuals or guides for specific instructions tailored to your device or platform.

@hillsh_vi The problem is that UIFlow2 was designed for the newer processors consisting primary of the S3 and C3 groups because of a fundamental change to the way Micropython operates on them including the boot loader.
You may have noticed that the older gen devices could be programmed without actually touching the cores where as the new gen have to be put into boot loader mode for firmware writing.

@RBOUMAN58
What version of UiFlow firmware do you have on StickC? As far as I know, the latest version of the firmware sometimes buggy, and the problem of not being able to scan I2C devices has occurred before. Maybe rollback to the old version will help.
