I’m trying to use a XIAO SAMD with a waveshare 2.13 epaper, but nothing ist o see on the display.
for the first test I’m using epd2in13_V4
Wiring seems to be OK (if there is no mistake in the table below).
There is no Output to Serial monitor.
I added a LED to see what happens. ON if sketch starts and OFF at the end. That ist working.
And I use the Builtin_LED to see what happens between ON and OFF. It’s blinking.
I guess the sketch is running.

VCC - 5V
