hf_stm32_temp_convert_fn

using hf_stm32_temp_convert_fn = float(*)(hf_u32_t raw_adc_count, hf_u8_t resolution_bits)

User-supplied function to convert a raw ADC count to Celsius.

For the STM32 internal sensor the typical formula is: T(°C) = ((V_SENSE – V_25) / Avg_Slope) + 25 but calibration constants differ per family (see RM).

For external NTC / PTC / thermocouple channels the user provides their own linearisation function.
