Is input pin 10 compatible with DS18B20?

Open rmeldo opened this issue 5 years ago • 3 comments

It's probably my fault, but I thought I would ask anyway.

Is it possible to read a DS18B20 using pin 10? I keep getting a -55C reading, whereas I should be getting ~20C.

I am using passive power with a 4k7 ohm pullup.

Thanks Riccardo

I cannot see a reason why this would not be working with PA10 ... Does it work on other pins ?

Is this still an issue ?

I would also think that any pin should work with the DS18B20, since that is OneWire which is typically bit-banged (unless you use some library that uses some other method and has specific requirements).

Lacking response from original poster, I would suggest closing this issue.
