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_Vis00GetTemperatureFromLut()

int16_t TS_Vis00GetTemperatureFromLut ( uint16_t adcVoltage_mV )

returns temperature based on measured ADC voltage.

Parameters

adcVoltage_mV voltage 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.
