In this video, we'll take our first steps (pun intended) towards creating a custom Zephyr device driver for a stepper motor. The next two videos will continue this journey.

00:00: Video Introduction
02:28: Introducing the Hardware
03:14: Schematic
04:41: Initial Implementation of Clockwise Rotation
12:05: Counter-clockwise Implementation
13:35: Moving Hardware Information to Devicetree Overlay
15:23: Implementing Devicetree Bindings
16:51: Implementing Higher Level API (rotate_degrees)

This is the sixth video in the "ESP32 on Zephyr OS" series, so I recommend watching the previous videos first:    • ESP32 on Zephyr OS
