Detailed Description

BaseTemperature adapter for the TMC9660 internal chip temperature sensor.

Reads the TMC9660's built-in chip temperature via the telemetry subsystem and presents it through the standard HardFOC BaseTemperature interface. Includes thread-safe statistics and diagnostics tracking.

Sensor specifications:

• Range: -40°C to +150°C
• Resolution: 0.1°C
• Accuracy: ±2°C typical
• Response time: ~100ms

Note

This inner class is owned by the handler. For host ownership of a BaseTemperature*, use Tmc9660TemperatureWrapper.
