Did you try to flash with the burner included with UIFlow Desktop IDE software? I had very mixed results using that burner with my StickC.

Things that worked for me.

I turned off my stickC and booted it just as the flashing process is about to happen.

Use the old fashioned way, flashing with esptool. Download the latest firmware from our engineers github page https://github.com/EeeeBin/UIFlow-Firmware/tree/beta and get esptool from espressifs github page https://github.com/espressif/esptool
It will tell you there how to install esptool and pyserial which are necessary for flashing. Once installed, open a terminal and go to the folder of the firmware you downloaded. enter the stick c firmware folder and there will be a flash.sh file, this script will flash the firmware to your device, but you need to make sure it has the correct usb device name written in the script or it will fail. By default it will have written USB_SLABtoUART, but stickc usually has a different named com port.

Give it a go, any issues come back here and ask

I heard one windows 7 user fixed his connectivity issues by installing FTDI driver, here are other forum posts related to this issue, maybe you will find some answers there.

@ajb2k3
Thanks for the info.
Can I use the upper port to get 3.3 Volt?

You should use 0,26 pins : Wire.begin(0,26)

@thrasher I wouldn’t worry to much as I keep forgetting the sequence

@bborncr
in UIFlow - add a label to the screen and then click on the label you just added to get the labels preferences up. there is an option to set it in that panel.
There is also a dedicated block for setting fonts.

@lukasmaximus Ah thanks for that. I think there are some links that need to be updated across the m5stack website if I ended up there then.

Hi @vany5921 I´m trying the way you said to me and I got an issue maybe for the pins I am using. I also tried with the Ucglib and I got a problem "ucg' was not declared in this scope" and I´m serching on the internet and it is a library issue. So I don´t really know how to do it :(

@ajb2k3 not yet, now i have other project on desk.
Simple sensors plus API ueFlow talk via p2p and Remote testing.
So far i was able to launch Ueflow downloaded SW and with small hack i am able to hold com with P2P via m5cloud.

It's simple, fill in the code from the example, hold the magnet to the M5stickC and you will see that the readings will change significantly! The magnet is needed strong enough, because The sensor is far away in the device.

@ajb2k3 Thank you very much for this information.

you could try to install the latest python, and esptool

@peter Sometimes you have to right click to get the translation function and sometime the page needs reloading. I view a lot of Chinese and Japanese pages and have noticed lately that the translator doesn't always appear.

@ajb2k3 Tried a different cable, so I'm assuming stick. Why not edit boot.py. It's micropython, as long as I call the M5 libs during the process, everything should work as intended.

@wikistik It would be nice to have a list of compatible "Safe" addons
As I said before, M5Stack units have internal 3v3 regulators to reduce the 5v down to safe voltage.
I have mentioned this in my UIFLOW book with the circuit diagram of the regulator.

@lukasmaximus very nice! That will be useful! Thanks!
