Hanterill

Engineering telemetry on a polling loop.

Hanterill polls and subscribes to data identifiers and plots them like instrumentation software: fixed axes, thin traces, no decoration.

Simulated drive cycle · sample data, not a vehicle reading

Channels

Choose channels above the chart. Battery and drive readings have ready-made groups, and the refresh rate follows what the car's control units can supply.

Reading the chart

Pause the chart to inspect a point. Gaps in the recording stay visible instead of being filled with invented readings. The trace shown here is simulated, not a reading from a car.
