Detection problem of a DS1820 on a NUCLEO-L073RZ
Hello. I'm having problems with a DS18B20 sensor. I'm using it on a NUCLEO-L073RZ, but everytime it's connected i get on debug : "Found 0 device Pinmap error: wrong port number" but if I disconnected the sensor, the program find one device that return "-0.6°C", and if I connect the sensor then, it return "-1000.0°C". That happened with the DS1820 library on the ds1820_HelloWorld program. I've tried several libraries and programs, but the result is almost the same, it doesn´t work. Do you know what can be causing it, and way to solve it? Thank you

That library is the same you already used, but now updated to work around the bugs and limitations of the STM mbed implementation. Hopefully in the future I can remove those workarounds again, but it should work now.
