If not specified, it is assumed that the pullup voltage is VDD. Therefore, the specified ADC IO channel must be configured so that VDD is used as the reference voltage. pullup-ohm: type: int description: | The pullup resistance in the circuit. pulldown-ohm: type: int description: | The pulldown resistance in the circuit. connected-positive: type: boolean description: | Indicates how the thermistor is connected in series with a pull-up and/or a pull-down resistor. If this flag is NOT specified, the thermistor is assumed to be connected-ground, which usually means a pull-down resistance of zero but complex arrangements are possible.
