press and hold red button then slide it out

@mnhj have you tried something simple first to start with it ?

@nalom1 this 5v and ground there is to supply sensors/units but voltage levels for gpio are 3.3

@hanktttop said in Cardputer COM Not Working:

@ajb2k3 Yes, I tested the first time this was suggested. In fact, the first cable I was using was just for charging a portable gaming console. Then I tried a few more, inclund cables for smartphones, external drives, etc. And I tested then on their specific devices, everything normal.

No idea why the cheapest one worked on cardputer, though.

I'm glad you have it working now...mark this cable up as Cardputer saver cable

yes Uiflow 2.0 web needs Uiflow 2.0 firmware inside controller.

@mearsuit i see this error from some time but projects are working ok

@frankqc said in How to use M5Unit-PoESP32 ?:

M5Unit-PoESP32

do you have any other controller to work with it?
The way I see it is that ie you have let say M5Core with some I2C units (sensors) connected to it
then add your M5Unit-PoESP32 connected to M5Core too over UART port (blue) to give whole setup access to local network and power ...

docs examples etc

New cable, same error. In fact, I just tested it on Fedora 39 (fresh installed), I still haven't been able to put the device in download mode. Maybe I'm forgetting a drive, which makes the device "recognize" the computer as a charger. Still, I reinstalled them all again, with no result.

I have M5Dial with StampS3 at the back...had to remove sticker to see and feel when "boot" button is pressed and hold before usb is plugged in - its almost hard to sense way different from pressing reset button where you can hear click.
With my Dial when say com13 was unresponsive then going in to boot mode made com12 to be available so in short words diff com for programming and different for boot mode - thats my experience with StampS3 from my M5Dial - i had it few times in some unresponsive mode.

usually when you press "burn" in M5Burner there is red button "erase" thats even without M5 module being detected, before com port selection

@literakl so are you able to display current time and battery level at all...forget about sleep option for now

@Mohir see this link

@LindzB said in Fatal error occurred:

fatal error occurred: Could not open COM3, the port is busy or doesn't exist.
(could not open port 'COM3': PermissionError(13, 'Access is denied.', None, 5))

Please, I need help in correcting this error.

Are you using M5Burner? is com3 detected in it for your device? is there diff software with your com port 3 opened in it in the background? lack of info about your hardware/software setup really

@mearsuit i see this error from some time but projects are working ok

@mentholmoose is it detected in M5Burner - do you see comX popup in the corner when device usb is plugged in? are you also logged in to your account in M5Burner - you will have to bind device in to your account at some point

@GregoryMorgan Welcome

@martincollett said in M5Stack 4IN8OUT connectors:

M5Stack 4IN8OUT

those are not usual ones

you prob need to read touch coordinates and if they are in range x1-x2 and y1-y2 (button area) function can be executed

@geex3 so test it first with official firmware/software to know if it works correctly

@simondid I know its not M5paper s3 but maybe worth a look e-ink with HA
