Lightning Talk: Introducing the New Zephyr Stepper Driver API
summary
Zephyr adds a stepper driver API (landed after a six‑month RFC with about 300 comments) that exposes concrete functions like set/get microstep resolution and set microstep interval, plus motion primitives move_by and move_to, stall detection, a tested shell and generic sample, and a common module using the timing‑source API to reduce boilerplate. Drivers range from GPIO edge‑bridge to integrated motion‑controller parts; current gap is a clean API for moving from point A to point B with a specified ramp.
