I have the problem that the DS18B20 sensors occasionally display -127 at runtime. I don’t poll the sensors cyclically.
I call the sensors in a FOR loop via “getTempC” + address. Even with a delay of 200ms after each call.
Based on the BIT resolution of 10Bit, I also note the processing time that is needed for this sensor.
In other words, with 3x sensors I even wait three times the processing time from the sensor before the values are called up again from the DS18B20.
What does it mean that these incorrect values occur at runtime. ?
