Hello,

Is it possible to connect two M5Atom with a cable by UART - without any additional equipment?
"White" socket used to connect sensors?
Possibly with an interleaved cable?
And using interrupts?

Kind regards,
Kajetan

OK, I think the solution is CAN communication.
The question is has anyone tested this protocol directly unit to unit,
without any hardware?

Pozdr.,

Hello,
I want to use three AtomS3 as buttons with variable description and functionality.
I don't know how to combine this as simply as possible with the fourth module - a "regular" Atom...

Reasons "why so as it":

• the settings of buttons 1-3 are related - e.g.: what appears on button "2" when pressed depends on what is on button "1"

• the main processor performs the task of processing I/O data over the UART, there is no time
  for other activities - for this reason, it must be informed by the buttons 1-3 about changes in their states - in a possibly low-engagement way

Can anyone give me a hint?
Może z użyciem któregoś z HUB (PA,PB)?
Wireless communication is definitely out of the question, the pause to receive any
message is too long.

M5 Stack is a musician's dream device - small, inexpensive, with a screen. Recording, routing, looping, etc.
You could really use a basic library like for a mouse. Just connect, receive, send.

For Core, Core 2 and other

Ok, Solved.
On cleared Arduino IDE, I install no M5Stack library, but "Unified M5Stack".
And ONLY M5Stack boards.
And other my modules ESP32 - WROOM, MH ET mini kit, Wemos D1 I can
programing as "M5Stack ESP32" and its work without any other ESP32
boards and libraries.

Hi.

I cannot install "M5Stack by M5Stack" library.
Board install ok. I see this library, click "install" and... nothing. :-(
Some message line flash only, and nothing else.

I have some experience with Arduino code.
I was programming Arduino UNO, MEGA, also ESP8266 and now ESP32.

I thought it was maybe because of the "garbage" of installed libraries and motherboards.
I uninstalled the Arduino IDE and only installed the basic Arduino and ESP32 espressif libraries.

Unfortunately - I still can't install the main M5Stack library.

Can you help me, please?

Kajetan
