Description

In the last version 2.3.5, parasistic mode doesn't work with DallasTemperature (with simple sketch). I think a delay is missing (the serial console scroll quickly). Values are 85 The 2.3.0 version has not the problem. Works fine. Serial console scroll slowy and the values are good. The DS18x20_Temperature, it's work fine with the two versions (2.3.0, 2.3.5)

Steps To Reproduce Problem

Launch the "simple" sketch (DallasTemperature). OneWire version 2.3.0 of OneWire: OK OneWire version 2.3.5 of OneWire: KO
