@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 ?

Hi, Had "my" StackChan delivered last friday, nice piece of kit, initially I could not login to app with my M5Stack account then had to try with new account (my son's) and went straight in. Can't wait to play with it ...when my son is at school - it was his late birthday gift from me...

@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

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

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

@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?

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

Hi, just received M5Tab, using what software/libs factory demo is done?

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

@fkarner Tak mam podłączone i odczyt wynosi ciągle zero

this works for me:

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

@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

@deckyon said in First Project - GPS on Core2 w/ UIFlow2.0:

So, I am working on a simple first project using the GPS. I am basing it off the one for the ENVII. I have a Core2 with UIFLow 2.0 Below is the code. It displays the labels, and displays what looks like data from the GPS, but it never changes and is not correct as if it is not finding satellites or even looking for them. Is there something else I need to do in the code to initialize the GPS Unit correctly. I am not a coder, this is literally my first time trying anything like this. I got the Core2 and the GPS to start learning. Yes, I have been outside and waited with clear skies and the Core2 has plenty of battery.

have you tried any of factory examples - easyloader or arduino for gps just to prove that it is working? also your GPS unit is the UART type - blue port correct? Do you have bottom expansion with blue port on your Core2? if no then you need to reconfigure it
your code: gps_0 = GPSUnit((13, 14))
GPS connected to PortA gps_0 = GPSUnit((33, 32))

@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

@MitchBuckanon M5Dial has 2 external ports PortA and PortB
PortA -> G15/G13/V/G
PortB ->G/V/G2/G1

Pins G15/G13/G2/G1 are programmable so can be used (reconfigured) to be SPI pins SCLK, MOSI, MISO and CS - needed to connect - communicate with - external device like Lan Module
