Hi,
I get what you mean, it makes a lot of sense. The one you get is surly the soldering mistake , because they didn't put enough tin on the soldering pad. We definitely could do something to improve structures deign just like what you come up with, but its not gonna help that much if we have the bad soldering.

The fisheye lens can be focused but most likely the lens is positioned to it's optimal focus prior to shipping.

M5 Wheel of BALA is connected with M5Fire via pogo pin ( gpio21 gpio22 gnd 5v ).

The IIC address of M5 Wheel ( 2-DC-driver module ) is 0x56.

@b1063n said in External Power - What is possible?:

So, did anyone find a solution. I was about to buy it, but then when I look at the documentation for the power supply voltage I cannot find it! Documentation is quite poor I must add.

I do not need battery operated solution, and the USB power is super ugly and inconvenient!

I need to use external 5V power supply connected to pins inside the board in a professional manner (no pcb hacking). Is this not possible? I cannot believe it!!

Yes it is possible as the Stackable modules provide internal power to M5Stack cores. (Sorry been working on my books and documenting units with demos this weekend.)

The documents I have, show that each stackable module has its own voltage regulator that delivers 5 volts to pin 28 of the internal bus (+5V).
If you look at the Proto module you will see that these pins are marked ready for you.

@yellowelise Yes, hareware reset

Thanks, I'll give those a try

@saka MPU9250 接了 GPIO 21, GPIO22 如果 DS3231 接 G21, G22, 之外的引脚的话，可以不冲突。 使用不同的 IICx

I've sent it back to shop and they confirmed it's device problem. And they replace with new one. Now no any problem.

@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
