DS18B20 temp sensor and Crowpanel 7"

Drak

February 24 in Products & Technology

Hi,
I connected my sensor on IO38 on my gpio_D connector and I have error -127C on my display.
I downloaded onewire and dallastemperature libraries.
I #define ONE_WIRE_BUS 38
Is there an issue with sensor and this board? Is it the the same issue I can read here with the 5"?
Thanks for your help.
