Node Ds18b20 error

I have a board ttgo esp32 oled lora v2.0.

the board assigned in Arduino board => HELTEC WIFI LORA 32

I get execute code following:

That code compiles OK here. Arduino IDE 1.8.5.

BoRRoZ · September 14, 2019, 7:13am

ok but it could be that he has some library’s more then one time (see red marker) and confusing his compiler

BoRRoZ · September 14, 2019, 8:29am

please keep it in one topic

mangulo · September 14, 2019, 9:12am

I try examples dallastemperature but I get same error. I have some wire wrong sure. Thanks

BoRRoZ · September 14, 2019, 10:08am

you have double libraries… (se encontraron VARIAS bibliotecas)

make sure there is only one temperature library

update - user continues questions here
