The closest thing is the blinky example that controls LEDs. Why is that? Zephyr expects you to write your own devicetree bindings. It's not that hard, and it's the topic of today's post.

Today we’re looking at a simple overlay file for the ESP32 architecture and talking about the syntax used to choose input and output pins. […]
