Hi , i have been trying to implement the DS18B20 sample of zephyr taken from GitHub 

I am having a lot of trouble in building the code , it comes up with very different errors each time with the same error message

-- Configuring incomplete, errors occurred!
FATAL ERROR: command exited with status 1: 'c:\ncs\toolchains\v2.0.2\opt\bin\cmake.EXE' '-DWEST_PYTHON=c:\ncs\toolchains\v2.0.2\opt\bin\python.exe' '-Bc:\ncs\v2.0.2\zephyr\samples\sensor\ds18b20\build' '-Sc:\ncs\v2.0.2\zephyr\samples\sensor\ds18b20' -GNinja

Hi Manas,

Can you link to the sample you are using?

Hi, I got it running now ! I downgraded the NCS to 2.0.0 from 2.0.2 and made these changes 

https://github.com/zephyrproject-rtos/zephyr/pull/37663/files/6434a3acc77bf843b9b3f3eeccc9870b38245014?diff=split&w=0

But 

We are using UART here I want to assign one GPIO open drain output and use only one pin .
