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.

Kind regards,

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