Timingproblem DS18B20

[PeterDDPain]

Hello there,

thank you for your nice Lib. Makes working with this sensor very handy!

I experienced a problem but maybe it is not a problem and i do something wrong.

I have a esp32 and the latest librarys from OneWire and DallasTemperature. But it doesent mater wich resolution is set, the conversion time is almost the same. I used the timing example with an arduino uno and with a esp32. I post here the different timings:

TIMING ARDUINO UNO

Test takes about 30 seconds for 4 resolutions RES TIME ACTUAL GAIN 9 94.00 751.10 799.0% 10 188.00 751.00 399.5% 11 375.00 751.00 200.3% 12 750.00 751.10 100.1%

TIMING ESP32

Test takes about 30 seconds for 4 resolutions RES TIME ACTUAL GAIN 9 94.00 496.95 528.7% 10 188.00 496.90 264.3% 11 375.00 496.95 132.5% 12 750.00 496.95 66.3%

Is there an issue with the lib or am I the issue by myself? :D

Thanks in advance Greetings

There is also the option of fake DS18B20's - https://github.com/cpetrich/counterfeit_DS18B20
