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

press and hold red button then slide it out

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

@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

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

yes Uiflow 2.0 web needs Uiflow 2.0 firmware inside controller.

@markram14

Does UIFLOW supports Modbus TCP - i'm trying to read Modbus device (meter) on my network by using M5GO on wifi?

does your stick loads ok with latest M5Burner firmware? Is user demo from M5Burner works? I can confirm that arduino M5stickCplus2 examples do work as had them in recently. Display, IR, Rtc, Battery, IMU, I've used Arduino 2.3.2, be sure you pick M5Stick Plus2

in simple terms you can't mix diff types(colours) of connectors on same device port,

is NTP unit/module available in uiflow 2.0 blocks? can only see RTC in Hardware

uiflow2 alpha 29 has rfid in it now

just connect voltage to sensor and measure what voltage it is giving out between output pin and ground. for 0 kPa your raw Analog value should be around 1300 i think

@dedsecaffiliate said in How do I charge the Cardputer?:

Well, I left it plugged in for 5 hours, and it's still showing as 75% charged. Anyone else have any ideas?

is it plugged in to "phone charger" or laptop/pc usb port?

@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

@Fernando-Cardoso said in Erase UIFlow 2 from M5Dial:

Hi, i need help.
I want to erase the installed UIFlow 2 from mi M5 Dial. When i open the M5 Burner and try to configure or to Burn, select the COM5 Port and can´t connect to M5Dial.
After try to connect it appears the error message:
A fatal error occurred: Failed to connect to Espressif device: No serial data received.
For troubleshooting steps visit: https://docs.espressif.com/projects/esptool/en/latest/troubleshooting.html
I press and hold the Button before connect M5 Dial to USB Port, try to burn from M5 Burner and the result is the same. it does not automatically connect to the COM5 port.

So, how can i erase the installed UIFlow2 from my M5 Dial?

Thank you.

turn M5Dial off, disconnect usb, press and hold boot button at the back while connecting usb, release boot button, now you should see different com port detected an it should be accessible to erase/burn

@zhoubinx M5 gpio/ grove are 3.3v so if your device side is 3.3 then all good, be sure that tx goes to rx and rx to tx, same baudrate and parity ....

@oldrichsveda

by looking on the CORE2 table you can see that selection of gpio is :
PPS enabled dip is for G0
TXD enabled dip is for G14
RXD enabled dip is for G13

so to connect PPS/TXD/RXD you need G0/G14/G13

@Kris said in AIN 4-20mA Is this correct?:

@fkarner Tak mam podłączone i odczyt wynosi ciągle zero

this works for me:
