point_one::fusion_engine::messages::WheelTickInput Struct Reference

Detailed Description

Differential wheel encoder tick input (MessageType::WHEEL_TICK_INPUT, version 1.0).

This message is an input to the device, used to convey the wheel encoder tick counts for one or more wheels. The number and type of wheels expected, and the interpretation of the tick count values, varies by vehicle.

To use wheel encoder data, you must first configure the device by issuing a SetConfigMessage message containing a WheelConfig payload describing the vehicle sensor configuration (tick counts signed/unsigned, etc.).

Some platforms may have an additional signal used to indicate direction of motion, have direction or gear information available from a vehicle CAN bus, etc. If direction/gear information is available, it may be provided in the gear field.

See also RawWheelTickOutput for measurement output.
