Industrial IO and You- Nonsense Hacks!
summary
Covers developing a Linux Industrial I/O (IIO) subsystem driver for a new sensor and ways to reduce system I/O by using userspace hardware abstraction layers instead of pure userspace drivers. Explains IIO concepts and APIs including channel consumers/definitions, software and hardware triggers (e.g. hrtimer SW triggers), the ring/buffered interface, and how to implement or extend drivers; includes demos of sensors using these IIO features.
