@cepics It's best not to stack two battery module with different capacity together.

Hi!
Here is an example (Korean but you can using code, Simple Chat Server)

And I will publish this document in English as soon as possible. :D

I had the same problem. But I did decide to rename all my APs and every device connected. 30 minutes later, still can't get a device code, and it seems like it got stuck booting into the "Press next for instructions" screen, so I can't change the wifi if I wanted to :(

@heybin I’m sorry, I don’t understand why when you have it working for the stick and the stack. Looks like it’s time for M5Stack to build a UIFLOW port of the firmware for the camera. If you build it from the sicks firmware then half the work is done for you!

awesome. got it to work now. thanks again!

PS:
The battery drain is not caused by the IP5306 itself, but by all the load is attached to (the 2V power the EA3036 on the main unit and the AMS1117 on the Lora)

@mrtarantl said in Pinout of TFT display:

Thanks :D i am aware of that... I was searching for a pinout of this

The contacts are not damaged, it should be easy to solder it again on the board and it will probably work again...
Of course, if you have minimal soldering skills...

@ajb2k3 yes I did use the cooling module as well.
My thought was that there probably is some electrical interference when using the stepper and the servo module together. My solution in that case will be that i disconnect the mbus from the voltage regulator +wire completely to only power the steppers with the external power supply and do the rest with usb power to the m5Stack, so i am safe :D

A component designator only makes sense if you have the correct schematic.

Have the ezTimeLog example loaded up. It is printing lines at the bottom of the canvas, and shifting previously printed lines up, indeed just like a terminal screen watching serial output. I think I misunderstood the scrolling functionality as the ability to use buttons to go back through the history at the top that had already scrolled off the screen. I see in issue #24 you say "canvas.print creates a buffer in memory that stores every print until it has scrolled off the screen", so that's not the way it works - sorry for my confusion.

Indeed, creating menu items that don't do anything would be a possible solution. I tried that early on, but found that once the menu was drawn (or run), it merely sits and waits for buttons. I have not tried creating a function that does an .addItem, then runs the menu again, and run that function with an .addEvent. I'll give that a try as soon as possible. Is there a limit to the number of menu items, other than memory constraints? If I'm successful getting the "menu" to redraw, I'll let you know, and I guess I'll see what the limits might be!

Thanks so much, @rop, your work is very appreciated!!!

@ajb2k3
Hello，I can not get your code in this post.

You also need to tune the drives way down low as it causes to steppers to overheat

Oh, I see the 150mAh battery

GOOOOOOD!!!
Works fine for me!
tnx very much!

My case (Fire version) does not allow me to reach the internal connector from the outside.

I've ordered a grey "version".

@lukasmaximus said in Button Unit Issue testing help please.:

I have tested the blocks associated with the single button unit and they definitely need some work.
Button press c shaped block only allows for a single press or release and the jigsaw shaped block
when combined with an if condition it throws an error that btn0_wasReleased or wasPressed is not defined.
These issues will be resolved in the next update and hopefully some extra functionality added.

Yeh, I was getting the btn0 is not defined error.

I've just taken several goes to write the firmware (I think my W7 laptop to blame).
It kept getting stuck in bootloader mode and wouldn't leave.
Finially got it to program and reset after pressing the on/off button twice.

Hi, We will put on sale a new product named "Bus" which is aimed for developers to expand I/O.

And here's the difference between with all cores. Maybe help you.

@watson
No, there was no COM-Port. As if it is not plugged or turned wrong around.
But as told, now it is ok. And i am glad it is. I like the M5s very much.

I still think, the capacitor solved it. But of course i am not sure.
