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.

@spectrad have you tried with the M5Stack example here?

he doesn't have M5Stack controller, only M5Stack sensor trying to read back to Arduino NANO so not esp32 board.

@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

@hanktttop said in Cardputer COM Not Working:

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

@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

@geex3 is your rfid 2 works ok with uiflow2 or arduinoon same devices?

I2C on Tab5 as example used with ENV3 sensor

i2c0 = I2C(0, scl=Pin(54), sda=Pin(53), freq=100000)
env3 = ENVUnit(i2c=i2c0, type=3)

@konacurrents any mac related drivers missing by chance?

so your setup is:
Mac --- usb A to C cables --- M5Atom

does Atom works on diff machine? I mean non Mac

have you tried to load EasyLoader example from M5Stak product page?

have you tried to use M5Burner and "erase" option first? have you tried to load any simple Arduino code? or any available EasyLoader project from M5 product page?
