@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.
@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).
usually when you press "burn" in M5Burner there is red button "erase" thats even without M5 module being detected, before com port selection
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
is NTP unit/module available in uiflow 2.0 blocks? can only see RTC in Hardware
Does UIFLOW supports Modbus TCP - i'm trying to read Modbus device (meter) on my network by using M5GO on wifi?
@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.
@mukul_100_ i would recommend to study some of YT VolosR examples of his approach to UI
open M5Burner, if you see comport detected when you connect M5Stick to usb then next step would be to burn CORRECT firmware to it as there are few versions for M5Stick
@nak750 said in Download shows 'Progress' but nothing happens:
Hi all, I am new to UIFlow and M5 Stack, I have done the Firmware flash using the M5Burner. Now using UIFlow, I can connect to the Serial Port, I can see the device sending default messages, then I press on Download, it shows 'Progress' but nothing happens. Can anyone please help?
I have tried the Download button on the right bottom of the UIFlow, this then shows Device Disconnected, but the webpage shows USB connected?
what M5Stack device do you have? some have to be in boot mode to allow programming, some accept new program straight away
@GreekAlex can you see comport being detected when you connecting usb in to it?
@MiguelM looks like rotation isnt right, what is displayed if you just burn easyLoader demo file or latest uiflow2 firmware from M5Burner?
@claraallison you could just drive relay to power IR illuminator when needed, you could do some logic inside M5stack based on light sensor or/and movement sensor to drive relay possibly. by that ir illuminator can be supplied by what kind of voltage it needs and M5stack only closes relay contact to power it up when needed.
@Bzh2ant2 is M5burner detecting any comport while your device is connected to usb?
when you open M5burner and you connect USB to your M5StickC+2 can you see com port number popup in top right corner of M5burner?
if so then download latest firmware for your M5StickC+2, hit erase, then burn
@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.
