Macro Definition Documentation

◆ TS_EPCOS_B57251V5103J060_POSITION_IN_RESISTOR_DIVIDER_IS_R_1

#define TS_EPCOS_B57251V5103J060_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

Definition at line 89 of file epcos_b57251v5103j060.h.

◆ TS_EPCOS_B57251V5103J060_RESISTOR_DIVIDER_RESISTANCE_R_1_R_2_Ohm

#define TS_EPCOS_B57251V5103J060_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.

◆ TS_EPCOS_B57251V5103J060_RESISTOR_DIVIDER_SUPPLY_VOLTAGE_V

#define TS_EPCOS_B57251V5103J060_RESISTOR_DIVIDER_SUPPLY_VOLTAGE_V   (2.5f)

Resistor divider supply voltage in volt

Function Documentation

◆ TS_Epc00GetTemperatureFromLut()

int16_t TS_Epc00GetTemperatureFromLut ( 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_Epc00GetTemperatureFromPolynomial()

int16_t TS_Epc00GetTemperatureFromPolynomial ( uint16_t  adcVoltage_mV)

returns temperature based on measured ADC voltage

Parameters
