Uno Wifi Rev 2

Hello westfw,
I tried your patched version of your onewire library and unfortunately it still gives exactly the same results. The board cannot communicate with the sensor.

I removed my earlier onewire folder from the documents/Arduino/library folder and added your modified library so I know I was using yours.

Thanks for trying to help I really appreciate it.

Hi all,

I'm having also the same issue with DB18S. The board is not able to read the sensor.

Everything works fine with my old Mega 2560.

Any ideas for remedy?

Hey,
I've been able to test my patch for SerialFlash on OneWire with a real sensor this afternoon.
Paul has been very kind and already merged it in master, so you can try it directly from that repo.

For reference, the patch is here Add support for ATMega4809 by facchinm · Pull Request #66 · PaulStoffregen/OneWire · GitHub

Hello, thanks for the update. I'm going to give this a try as soon as I'm near my hardware.

Hello,

I have the same problem.
It says that my temperature is -127.

Have anyone solved this problem?

Hello -
The updated onewire library at GitHub - PaulStoffregen/OneWire: Library for Dallas/Maxim 1-Wire Chips, referenced by facchinm above, solved the problem for me.

Hi, thank you for the new librairy !!!

It also works perfectly for me :slight_smile:

Hi,

Yes it works fine now. Great job!
Thanks

Hi,

I encountered the same issue using a temperature sensor DS18B20 with an Uno WiFi Rev 2. It is the OneWire librairy that is defficient on this board. To solve this issue you can try to replace it with this other library :

It seems to work fine with me.
