IIO (Industrial I/O) is a new kernel subsystem to allow easy userspace interaction with data capture devices (ADCs, DACs, accelerometers, light sensors, etc), while maintaining a high level of performance. Based on a recent driver contribution using this subsystem, we will detail how to build a simple driver using this subsystem and explore how to use advanced features like triggered captures or buffering. We will also explore IIO user space API and how to use it.
