@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.
@mnhj have you tried something simple first to start with it ?
@bdtprez general rule is to keep controller firmware same as web uiflow version, so current web uiflow 2.0 is 2.0.1 and such firmware is available via M5Burner, Uiflow 2.0 has build in firmware manager too. (botom left hand side).
@Cognitive5525 said in AIN4-20mA Unit to Arduino Nano Every:
he doesn't have M5Stack controller, only M5Stack sensor trying to read back to Arduino NANO so not esp32 board.
usually when you press "burn" in M5Burner there is red button "erase" thats even without M5 module being detected, before com port selection
Inspired by VolosR I've started to play with SLS a bit, rotating image based on M5Dial encoder, touch buttons, arc/slider, rotating fan image,
is NTP unit/module available in uiflow 2.0 blocks? can only see RTC in Hardware
just open M5Burner, erase it and burn correct firmware to your Stick
@obstbauer this is uiflow example with raw value and float too
Does UIFLOW supports Modbus TCP - i'm trying to read Modbus device (meter) on my network by using M5GO on wifi?
@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
@GreekAlex can you see comport being detected when you connecting usb in to it?
@obstbauer TBH if you are using M5Stack modules/units with not M5Stack controllers maybe its worth to have at least one M5Controller (atom?stick? )to be able to check module functionality
@chr1g1 said in MQTT and AWS IoT Support in UiFlow 2.0:
how? You produce python code or use Blockly? At least in Blockly, I don't find a block. I'm trying to use this for a workshop with people who are not fluent in coding -> Blockly.
with Uiflow2 on your left hand side window under unit you should have some config options software/hardware/ modules/units - MQTT isn't added to blocks by default - you need to add functionality you interested to use.
I'm using Hive MQTT and had to use "execute code" to have it working on uiflow2 but not tried on latest version
@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?
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
