@ firehopper,
The button you have to press on M5Stick C is this one, see picture !

Hello to everyone here.
My name is Reiner, I live and work in Germany. I work as an assembler for a company that manufactures hall cranes. I think the M5Stack is great, not like the Arduino loose circuit board and so on, but the m5Stack and the sensors all compact and well thought out packed in housings.
Unfortunately I don't always have so much time and I would be happy if sometime a manual and also UIFlow would appear translated into German.
I have a little knowledge of Arduino, but I am not the great programmer.
Since I also have other hobbies like 3D printing with the Anycubic Photon,i3 Mega S and the Chiron and milling with a portal milling machine for model making (Stepcraft-2/D.420).

I'm just fascinated by writing, programming, drawing and when it's done the printer or the milling machine or the M5Stack does it.

And the possibilities are almost unlimited because there are so many sensors, I'm still at the beginning and have to understand the M5Stack, unfortunately there are only books about the ESP32, but maybe it will change when there are more people who use it.

Maybe someone here has a tip how and where I can learn the M5Stack and programming , would then like to program with Arduino or UIFlow !!

@ajb2k3 , @lukasmaximus ,
thank you for the Short answer!!

Now I have understood what the ISP program adapter is good for

Thx! Reiner

@liemph,

here are some more interesting pages about the RCX.
Maybe very interesting for you if you still have so many RCX parts.

P.S. I'm waiting for two of the X-Base units, they're already on their way to my place

@shotokutech said in M5StickC restore factory demo firmware:

Good day.
I have spent a little while searching the forums before posting this question. Can you please advise how I can restore the factory demo firmware on the M5StickC after I flash UIFlow firmware and load other programs. I hate to depart from the starting point, without knowing how to get back. Thanks in advance.

Hello ,
go to the documentation page of M5Stack to M5StickC (https://docs.m5stack.com/#/en/core/m5stickc)
go here to EXAMPLE there load the file (M5StickC facory test code) this you write with the Arduino software into the M5StickC
and you have the M5StickC back in its original state with factory demo firmware.

@ekalfwonS ,

this is only possible inUIFlow not in the Arduino software, in UIFlow you see Project in the upper left corner, on the right side you can assign a name for your program. Then go to the far right and select Download by clicking on the last icon. This will save your program as you named it on the M5Stack Fire.

Hallo liebe M5Stack Fangemeinde.
Habe folgendes Problem, Starte UIFlow Version 1.5.1 mit dem USB Kabel ist der M5 Stack Fire mit dem System verbunden. Nun verbinde ich die beiden mitteinander was mir auf dem Bildschirm mit dem grünen USB Zeichen als verbunden angezeigt wird (siehe Bild). Will ich nun z.b. eine Demo überspielen, so schaltet sich unverzüglich der M5 Stack aus und meldet sich anschließend wieder mit dem vorhandenen Bild. Stimmt da noch was nicht !?
Betriebssystem ist Windows 10

Gruß Skink!

When will the Desktop UIFlow version 1.6.2 be released !

@curlybrace said in LEGO+ and PowerFunctions:

Hello all,
I would like to connect (old) Lego PowerFunctions motors to the LEGO+ module. There are a few things I need to solve for this. But if anyone has already done so, perhaps I can save some time. I will write up a detailed step-by-step once I get it to work.

The PowerFunctions motors are 9V. I see that the LEGO+ module can take external power input (the yellow XT30 connector) with a nice wide range of voltages, but I also see that the pins on the ports are labeled "5V" (https://docs.m5stack.com/#/en/module/lego_plus). Does anyone know whether the input power Vcc is passed directly to the motor connectors? I also read that the voltage on this external input is passed directly (i.e., unregulated) on to the M5Core itself; is it safe to put 9V on this input?

The module came with a connector cable to an EV3 "telephone type" connector. I have found descriptions of the LPF2 connectors, so I can just buy connector cables from Lego themselves (they're only a few euros each) and cut them up to make compatible connectors. I found "compatibility cables" online, but they are not the correct PowerFunctions type.

Did anyone here try this before? I found a YouTube video of someone who connected a PowerFunctions motor to an M5Stack, but it was just 30 seconds of a motor spinning and no details about the connection itself...
Cheers,
Sander

Hi, Sander,
that wasn't one of those videos by any chance !?

Link1: https://www.youtube.com/watch?v=W1jNzYjn_bc

Link2:https://www.youtube.com/watch?v=xm5Hdaia7po

These two videos are from me !

But I used the BASE X module (https://docs.m5stack.com/#/en/base/basex), there you can connect all Lego motors from Lego EV3, NXT, Power Motors L, XL and what other Lego motors are available !

On the subject of connection I will add more interesting pages:

Link5:https://freggelweb.de/technic-powerFunctions.html (Go all the way down to the end of the page there you see adapters, but don't know if the adapter cables are still available )

That's good news for once, the prices also look acceptable. I'm going to go check it out. Only at the moment almost everything is sold out, it's certainly also due to the Corona virus. I hope they get this under control and you can order again.

Fingers crossed for everyone over there!

Greetings skink

have now checked it with the second M5Paper but this can also log on to the WLAN and also syncronize. But just the first time, then I am also with this an active connection on the M5Paper displayed but in the WLAN of the router but he is grayed out (so no longer connected) and a second syncronisieren fails!

Have this morning the M5Paper connected to the WLan, which is displayed to me on my router and on the M5Paper.
But if I then go to "Sync Time" writes me the M5Paper WLAN not connected !?

Is there perhaps a bug in the software?

After I have reloaded the factory test software with the M5 Burner, logged into the network, set the time zone and then perform the function Sync Time works, but then I see how the M5Paper disappears again from the WLAN on my router and at another attempt with the function Sync Time the function no longer works!

It would be nice if I had it too. Unfortunately I can't find a supplier in Germany who delivers it.

Thanks for the Info, i have Ordered at Aliexpress!!

Hi Felix,
yes I noticed and ordered 2 directly!

Hello M5Stack Freaks,
Do any of you already have one of the new sensor Ampmeter Unit (ADS1115) or Voltmeter Unit (ADS1115) !
greeting skink

@felmue

You write (One thing that is not clear to me is whether the 18650C HAT can charge its battery on its own, e.g. w/o M5StickC installed. Does it have its own charging IC?)

The 18650C HAT is charged exclusively via the USB port, no M5StickC is required! The USB port is only for charging, otherwise the USB interface has no function!

Greeting skink

@flatline69 ,

I just tested your setup, I have several M5StickC with blue 5V sticker and also two 18650C HAT.
I built the M5StickC with blue 5V sticker two pieces and the two 18650C HAT together and also screwed them together. But the M5StickC don't get warm!

Either, as @felmue writes, it is because of the charge current if it is not set to 100mA.
Otherwise it would be interesting which version of the 18650C HAT you have, because there are probably 2 versions of it. Unfortunately there is no version imprint in my version, but according to the documentation there should be no difference except for the additional mounting option.

So I guess in the end:

1. the charge current in the M5StickC is higher than the 100mA.
2. because you got an (Error 22) message that the internal battery is defective (deep discharge)
3. the M5StickC is defective (internal battery defective)
4. the 18650C HAT is defective, loose or defective components on the board lead to your result!

Good luck skink

@m5stack

Mh there are Barometric Pressure Unit (BMP280) & 6-Axis IMU Unit (MPU6886) supported, but what about the other units !

TVCO/eCO2 Gas Sensor Unit (SGP30)
Hall Effect Unit (A3144E Hall Sensor)
Voltmeter Unit (ADS1115)
Ammeter Unit (ADS 1115)

When are these units transferred to the UIFlow software !

Hello Felix,

Thank you, I have tested your program and it works perfectly. Thank you very much for that !
