Thanks Teastain
I have the expansion module for CORE 2
I am looking for advice on the mode of communication to use to transfer from CORE2 to the ATOM Display, and how to transmit around 20 digital variables?

What is the simplest and fastest communication solution (Modbus, UART, CAN,...) to communicate around 20 variables from a CORE2 to an ATOM DISPLAY? the two controllers will be in the same box at 10cm.
Should the data be sent as a list? do you have any examples in UIFLOW?

Same problem with the CORE2, do you have a solution for this error with M5burner V3 under win10

The update 1.9.7 works well, but impossible to configure the ATOM Display still the error message "Get configurations failed"

impossible to use the ATOM Display without the API Key

@lishengkkk all it takes is a small stroke of the cutter and the track is cut cleanly.
I scraped off the white paint to get to the copper. So if needed a drop of solder and everything works as it did at the start.

@lishengkkk I only use UIFLOW, no need to change the code once the connection is cut

@ajb2k3 J'attends avec impatience la version Française. super boulot, félicitations

With the M5Paper, Uiflow displays Alpha M5Paper and not 1.9.2...
