Macro Definition Documentation

◆ TS_EPCOS_B57861S0103F045_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 (R1/R2),
     different R_ntc values are used for the calculation.

Function Documentation

◆ TS_Epc01GetTemperatureFromLut()

int16_t TS_Epc01GetTemperatureFromLut ( 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.
