#define BETA_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 R2 in the above circuit diagram
