Dial

Human-facing detented dial input module for LibXR/XRobot projects.

Dial consumes two LibXR::GPIO phase inputs and publishes discrete clockwise / counter-clockwise events through LibXR::Event. GPIO callbacks sample the Gray code phase changes, while OnMonitor() aggregates them into detent events. Event payloads are stored in an internal queue and can be read with GetEventResult().

Typical aliases:

• dial for the logical event source
• dial_a for phase A
• dial_b for phase B

The module intentionally models a hand-operated dial, not a motor feedback encoder. Push-button handling should stay in a button module such as BitsButtonXR.
