@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.

@spectrad have you tried with the M5Stack example here?

he doesn't have M5Stack controller, only M5Stack sensor trying to read back to Arduino NANO so not esp32 board.

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

@marryjoseph22 what M5Stack hardware do you have to play with?

@marryjoseph22 if you want to try Arduino way..i can recommend YT and VolosR approach to M5Stack devices, his UI design is top notch

for beginners uiflow blockly is good start and it can switch easly to micropython in same window

@Marcy72317 could it be in sleep mode?
can you properly switch it off and on then try easyloader?

@Marcy72317 is there any messages on com port monitor in M5Burner you see on this device?

@Marcy72317 easyloader demo from m5 stack docs page for m5stickC +2

@Marcy72317 have you tried easyloader from m5stickC+2 docs page?

@himlol is comport detected in M5Burner?
do "erase all" option then pick up correct firmware M5StickC, M5StickC+, M5StickC+2

@GusBel use M5Burner and load fresh firmware

@flyingjeepman on/off button on? is M5Burner detecting com port when usb is connected?

@l-roca what happens if you do intensity conversion outside set brightness block then use this variable for set brightness to .... block

other words does set brightness to 25, 50, 75 works fine with fixed values in it?
