@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 ?
usually when you press "burn" in M5Burner there is red button "erase" thats even without M5 module being detected, before com port selection
@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))
Does UIFLOW supports Modbus TCP - i'm trying to read Modbus device (meter) on my network by using M5GO on wifi?
is NTP unit/module available in uiflow 2.0 blocks? can only see RTC in Hardware
@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.
added photo explains it,
you have no Core2 bottom extension with uart blue portC on it.
you are connecting UART type gps unit (blue port) in to Core2 default I2C port - which can and needs to be reconfigured to accept UART type of communication
@gdbongle said in Writing serial output from sensor to USB stick connected by M5Stick's onboard USB-C port:
I'm trying to get data from a sensor connected to my M5Stick and put it in CSV format to be written to a USB stick for later processing (including timestamps) but I'm not sure where to begin, nor have I found anything of relevance on the forums/docs. Is there somewhere I can begin?
writing in to SD card would be one to start from I think
@ivosak when you left it connected to charger was on/off button in ON position?
@mb you can use hide/show/set based on condition for items on different screens,
I would recommend "VolosR" github/YT for UI design approach but this is arduino mostly, also there is block to run your code in blockly
@mb button, timer etc needs to be added in left hand menu below controller image "software/hardware" in manner you would add module or unit
@mb is device showing as connected still after first "run"? usually should be but if you use upload then wifi block should be included in the code so unit is connected to network, can you try same with uiflow2?
@mukul_100_ what software you planning to use?
see uiflow2 init example
@ivanurwin get yourself M5Burner, log in to it with same credentials as for uiflow2, then find newest firmware for your device to burn it in to it via m5Burner
@PhilB79 said in M5CoreS3: "ERROR Device type unknown" when trying to connect both CoreS3 and CoreS3 SE to Server.:
@teastain
UIflow 2 / Select device / RED dot next to the CoreS3 graphic. Same applies to CoreS3
silly question but you are logged in to Uiflow2 with same login credentials as in M5Burner (bind)
@PhilB79 so after such process is your device showing connected to uiflow cloud? is it showing your email address (all should be visible on device startup page)
see my core2 example
