Add Support to M5AtomS3

[oxbown]

Please consider to include AtomS3 to the build list, with platformio this could be really easy.

Updates:

board = m5stack-atoms3 is not pressent in platform = espressif32 @ 3.4.0 so need to update the Platform enviroment.
If update to the newest release "6.3.1" hundreds of errors appears.
error: a reinterpret_cast is not a constant expression

need more investing

I compared board definitions of ATOM and ATOM-S3. It strikes me that S3 has no "CAN" connectivity.
Are you sure that S3 is right plattform?

Espressif renames CAN BUS to TWAI so with new boards libraries like "NMEA2000_esp32" not compile.

A possible solution here --> Commented here

I'm trying to test the new twai version but something is not working properly. When I connect my m5atoms3 lite with the can bus unit to the N2K network seems that the atom can not read the nmea2k data.
The "NMEA2000 State" in the "Status" page witches between "[32] BUS_OFF" and "[32] OFFLINE", everything is connected correctly (including 120ohm resistances).
There is only one N2K device on the network (plus M5atoms3), an Airmar P79S deep transducer.

How did you build & install the firmware?
Did this set up ever work before?
How exactly did you connect the device? CanH/L + ground? Are you sure about the wires - sometimes colors are different!
And please enable the debug log via the UI, connect an terminal via USB and send the output (especially from start up).

i cannot confirm the behavior. this works as expected

Well...sorry, CAN works ok... i´d made a mistake wiring the devices... i can confirm that latest main works on ESP32-S3.
