Macro Definition Documentation

◆ TS_MURATA_NCU15XH103F6SXX_POSITION_IN_RESISTOR_DIVIDER_IS_R_1

#define TS_MURATA_NCU15XH103F6SXX_POSITION_IN_RESISTOR_DIVIDER_IS_R_1   (false)

Position of the NTC in the voltage resistor true: NTC is positioned above the voltage tap for the ADC voltage. This equals resistor R_1 in the above circuit diagram

false: NTC is positioned below the voltage tap for the ADC voltage. This equals resistor R_2 in the above circuit diagram

◆ TS_MURATA_NCU15XH103F6SXX_RESISTOR_DIVIDER_RESISTANCE_R_1_R_2_Ohm

#define TS_MURATA_NCU15XH103F6SXX_RESISTOR_DIVIDER_RESISTANCE_R_1_R_2_Ohm   (10000.0f)

Resistance value of the other resistor (not the NTC) in the resistor divider in Ohm.

Function Documentation

◆ TS_Mur00GetTemperatureFromLut()

int16_t TS_Mur00GetTemperatureFromLut ( uint16_t  adcVoltage_mV)

returns temperature based on measured ADC voltage.

Parameters
adcVoltage_mVvoltage in mV
Returns
corresponding temperature in deci °C or INT16_MAX/INT16_MIN if NTC is shorted or got disconnected. The caller of this functions needs to check for these return values to prevent invalid data.
