Thank you Calin!

Hello, Calin,
I allowed myself a tiny mod to your App. Now it can be launched from the SD card under SD-Menu from tobozo. https://github.com/tobozo/M5Stack-SD-Updater.
Modification consists in main.c mod and extra libraries. Just unzip Matroska.zip to project folder and build. Resulting firmware.bin in .pioenvs\m5stack-core-esp32
is compatible with tobozo loader.

@kabron 在 Serious Competitor Appeared 中说：

FACES modules have none documentation at all.

yeah... i must agree with you on this one...

Check the project idf config using make menuconfig option.
In this situations, a debugger will be very helpful.

Gone again and a new lead didn't solve it.

found it - it's a Seeed Studio Wrapper

Ii just recently ordered these stacks and i guess you save me a ton of work.
thanks for taking the efforts of sharing.

@drwino

I'm getting
0.29a switched off.
0.39a running factory test.
Using a USB power meter.

to measure battery you need a test meter
Can't measure this tonight as cant find small allen wrench.

I can power it through my mobile phone charger or a battery pack, just using a tiny USB3 Adapter; and I can power it off my solar panel. I just like the idea of having a web server (or whatever else I made ...) that I can plug into an AC socket.

Can only be mechnical, meaning the connectors don't quite mate without the proto board in-between. Try pushing a little harder?

Hi @ajb2k3,

I gather you are talking about the internal MBUS GPIO pins - that connect the modules together.

The pin pitch - distance between the pins - is 2.54 but the pins are height reduced compared to those found on a standard GPIO header - too SHORT for Dupont connectors to attach.

The MBUS pins are intentionally height reduced in order to minimise the overall height of the M5Stack.

It is possible to source a third party full height 30 pin GPIO header if needed, or you can make one using a GPIO for Arduino or Raspi. You could get a PCB made to go with it, based on the files available on github, see here.

Hi @ajb2k3,

Are you actually using Arduino IDE version 1.6.5 from 2015 - or is that a typo ?

From your comments, I am not sure what issue you have found.

Depending what sketch you are trying to load will dictate what libraries will need to be referenced at the start of the sketch, such as those you list.

If you are having problems loading the examples, perhaps pick one and outline some specific details including error messages.

Hi @lastcaress,

You should be able to flash the standard M5Stack firmware onto the M5GO (you may need to use the "Erase" function on the ESP Flash Downloader Tool first).

If you want to use M5Cloud you will need to load the M5Cloud firmware onto the M5Stack - it is available here.

Not sure if you will be able to use the sensors using the same code - it depends how it is all setup.

Hi @Zathras0,
That seems a weird error to get from running M5Stack's simple Hello sketch which does not include a poweroff function. (?).
Also I don't know the "ResetReason" sketch that you referred to. Where did you find this ?

(1)OK it seems you have the M5Stack library installed in the correct place.

(2) Is the Espressif ESP32 library installed ? Check: C:\Users\█████\Documents\Arduino\Hardware\espressif\esp32\libraries . If you don't have files there go to M5Stack setup guide and install them.

(3) As PépéMax suggested, in the Arduino IDE, check that the M5Stack is selected as the board that you are using with the IDE. On the Arduino menu go to /Tools/Board . The M5Stack should be set here as the board you are using.

@PépéMax

'...some function of the ESP32 does not work yet for the M5Stack library like analogWrite()

Just to clarify, as I understand it, the issue is that not all functions available on Arduino or ESP8266 boards are available at present on ESP32 boards in general - eg: analogWrite();. That is, the problem is not specific to M5Stack boards - it effects all ESP32 boards. Referenced here

@dimi 在 FACES UI Lessons question 中说：

The information in the previous lesson, today is not relevant.

So, these lessons only misinform us. So I ask, what is the use of them?

It is better to rewrite or delete them.

А где схемы и прошивки?

@ajb2k3 在 Project Element E 中说：

Brushless drivers are ok for the Brushless motors but the same board needs to replace a burned out driver in an old bike.

The old bike has a 200W motor run at 36v for a total of 5.55555) amps and the FQA160's are rated at 160amps.

However, I must say that those ESC's do look sweet.

In this case, consider something like this:

Is way cheaper.
