<![CDATA[AtomS3 0.85" OLED unable to wake from buttom]]>Recently tried using the AtomS3 with 0.85" OLED for a CAN-bus project and it seems like a missed opportunity to not have the (only) button under OLED connected to a pin that support waking up the ESP.

Is there an easy workaround for this?

I would also have to find a way to put the isolated CAN bus base to sleep to make this project viable with M5Stack products so I guess odds are I'll have to make my own, but I would be nice if new products were designed with deep sleep and power saving in mind.

https://docs.m5stack.com/en/atom/Atomic CAN Base
to work with the AtomS3, immediately TWAI_ALERT_ERR_PASS, TWAI_ALERT_BUS_ERROR

https://docs.m5stack.com/en/unit/can
works, though.
What CAN library did you use? With what pin definitions?

Thanks in advance!

You can read that button and do whatever your program needs, even transfer the input directly to an output.
