Have you spoken to anyone on the Micropython.org website about this? UIFlow and s built on Micropython , not the creator of Micropython

Burner is for updating the firmware that comes pre installed. I can’t test as I am still waiting for my station to be dispatched

@rotor This is quite simple on the Core: With the "Graphic" blocks it is easy to create graphical pages with "labels". Unfortunately, this is not so easy on the Core2 and functions are missing. You do not use labels, but the following 3 blocks: [Lcd.clear]; [Font:...]; [Lcd.print "Label1" x: 0 y: 0 Color...]; [Lcd.print "..." x: 0 y: 20 Color...]; etc. You can first design them graphically by dragging labels onto the screen to determine the position, to then copy the screen with the graphic blocks, test whether all text appears on top of each other, and then edit the dragged labels. remove. Use the "Functions" ("dosomething") blocks to create a page (Page1, Page2, etc). For example, by making "Setup" followed by a block "Page3", only page 3 will be visible, without using labels and you still have all the flexibility. I hope that's how I answered your question. This is how I create multiple pages.

@felmue thank you. I've installed VS Code, and installed the PlatformIO IDE into it. Under Devices, it can see the one corresponding to the M5paper. Under Boards, it offers many of the M5 APIs, but M5paper isn't in the list. I can open the "M5Paper_FactoryTest" project; it has "board" set to "m5stack-fire". After a few false starts, it builds and installs on the device, so that's all good. Is there anything I can/should do to set the board correctly? Does it matter?

@chriszang and another update. So I am happily working on my CAN receiver sketch and just noticed that I forgot to press the button that grounds INT-output of the mc2515 but the upload still worked. Gave it another try (w/o pressing the button) and it's still working - weird. Then I swapped this COMMU module for my 2nd COMMU Module and here the upload doesn't work. My explanation is that the grounding of the mcp2515 INT-output basically created a short circuit in the transistor that controls this pin and eventually burned it out. Not a big problem for me as a) I am not using interrupts in my sketch b) I have a 2nd COMMU unit I just wanted to warn you guys that grounding the INT output has unintended consequences.

Hello @RolfF It's a design mistake. It is a basic mistake to add 5V to 3.3V system. 5V enters the RF circuit, causing deterioration or damage. There are many cases where ATOM has already broken. : M5Stack Community Short Wifi effective range and IO0=3.9V issue with Lite and Matrix : About a year ago https://forum.m5stack.com/topic/3048/short-wifi-effective-range-and-io0-3-9v-issue-with-lite-and-matrix : M5Stack Community New CH552 firmware for Short-Wifi-Issue of M5Atom/Stick/TimerCAM/etc. : About 9 months ago https://forum.m5stack.com/topic/3768/new-ch552-firmware-for-short-wifi-issue-of-m5atom-stick-timercam-etc : Bugs and measures for M5Stack ATOM : 2021.10.10 https://macsbug.wordpress.com/2021/10/10/bugs-and-measures-for-m5stack-atom/ : Other measures : Low the voltage of GPIO_0. digitalWite(GPIO_0,LOW);

@ajb2k3 I’m afraid but I’m not the author of that post. But, I agree that it’s a well written one. Regarding device shadow, this is what I meant: Interact with device shadows

Yes the baud rate is correct. The characters are not random. They appear to be a CRC error and it is being sent in hex rather than ASCII. Anyway, I found that if I loaded the ESP32 generic binary file then it works. At least I can get to a Micropython REPL prompt. Of course, this version is probably going to me missing the libraries that I will need. I guess I will have to build my own binary version.

I think I probably have a defective unit. I have tried with only a single tab open, latest version of Google Chrome, tried it incognito mode also just to be sure some extension wasn't getting in the way. Despite all efforts it never connects to UIFlow. I know it's on the network because my router is showing it connected and sending/receiving some packets. I will probably stick with devices that have USB-C on them, this is way too much hassle and I don't want to have to rig up a programmer just to toy around with a prototyping device. Oh well, at least I'm only out $5.

Hello @KjaerN the 8Servos HAT examples seem to be here. The M5StickCPlus ino file is here. And the file you mentioned is here. Thanks Felix

Hallo @cheffeundwackl versuche es einmal mit der neusten UIFlow firmware (v1.10.3) fuer den M5Stack Fire. Das M5Burner tool (v3) ist hier. Nach Abschluss des Burn Prozesses sollte der M5Stack Fire automatisch neu starten und sich mit dem UIFlow Backend verbinden. Manchmal braucht das ein paar Sekunden. Einfach geduldig warten. Wenn alles richtig ist, ist keine manuelle Aktion auf dem M5Stack Fire vonnoeten. Dann verwende https://flow.m5stack.com (sollte auch v1.10.3 anzeigen oben links). Falls nicht, Browser Fenster neu laden. Danke Felix P.S. ich habe das YT Video nicht geschaut, nehme aber an, dass es veraltet ist.
