Macro Definition Documentation

◆ TS_MURATA_NCU15XH103F6SXX_ADC_VOLTAGE_V_MAX_V

Defines for calculating the ADC voltage on the ends of the operating range. The ADC voltage is calculated with the following formula:

V_adc = ( ( V_supply * R_ntc ) / ( R + R_ntc ) )

Depending on the position of the NTC in the voltage resistor (R_1/R_2), different R_ntc values are used for the calculation.

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.

Here is the call graph for this function:

◆ TS_Mur00GetTemperatureFromPolynomial()

int16_t TS_Mur00GetTemperatureFromPolynomial ( uint16_t  adcVoltage_mV)

returns temperature based on measured ADC voltage

Parameters
adcVoltage_mVvoltage in mV
Returns
corresponding temperature in deci °C
