Hi Paul, correct.

Just rename the old OneWire_direct_gpio.h file in the Arduino\libraries\OneWire\util directory to, for example OneWire_direct_gpio.h.ori , just in case.

Copy the new file with the same name from https://github.com/devastar/esp32c6-zigbee-ds18b20-temperature into your Arduino ...

Thank you, I found the solution of the problem,
which can be found in the file OneWire_direct_gpio.h at https://github.com/devastar/esp32c6-zigbee-ds18b20-temperature
OneWire has the problematic file in library directory at C:\Users\user\Documents\Arduino\libraries\OneWire\util on a windows10 ...
