Detailed Description

Unit conversion functions and constants.

Function Documentation

◆ temperatureAddOffset()

static constexpr uint8_t temperatureAddOffset ( int16_t temperature )

inlinestaticconstexpr

Convert an internal temperature value (-40 to 215°C) to a storage value (0-255).

Parameters

temperature in °C, from -40 to 215.

Returns: uint8_t

◆ temperatureRemoveOffset()

static constexpr int16_t temperatureRemoveOffset ( uint8_t temperature )

inlinestaticconstexpr

Convert a storage value (0-255) to an internal temperature value (-40 to 215°C).

Reverse operation of temperatureAddOffset.

Parameters

temperature

Returns: int8_t

Variable Documentation

◆ CALIBRATION_TEMPERATURE_OFFSET

constexpr int16_t CALIBRATION_TEMPERATURE_OFFSET = 40

constexpr

< All temperature measurements are stored offset by 40 degrees. This is so we can use an unsigned byte (0-255) to represent temperature ranges from -40 to 215
