Macro Definition Documentation

◆ TS_VISHAY_NTCLE317E4103SBA_POSITION_IN_RESISTOR_DIVIDER_IS_R_1

#define TS_VISHAY_NTCLE317E4103SBA_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

Function Documentation

◆ TS_Vis01GetTemperatureFromLut()

int16_t TS_Vis01GetTemperatureFromLut ( 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.
