Hello everybody,
i succeeded to get the output from BME280 and MPU6060 sensors
I need to merge them together
Kindly, I need help to Setup prj.conf file
Thanks & Regards
You can put both the BME280 and the MPU6060 dts nodes inside the same I2C node instance. Check how it's done in the board thingy91_nrf9160: https://github.com/nrfconnect/sdk-nrf/blob/v1.7.0/boards/arm/thingy91_nrf9160/thingy91_nrf9160_common.dts#L107-L126
Best regards,
Simon
Rihab said:yeah but how do i put them together in the same project ?
i just put the 2 project in the same file and then i create the dts ?
If you want to merge two projects, you simply merge both of the corresponding files into one file. E.g. merge bme280/prj.conf and mpu6060/prj.conf into bme280_mpu_6060/prj.conf. Do the same with the .c/.h, overlay files, CMakeLists.txt and so on...

thanks Simon
i think you got what i want to do
now i' trying to combine the 3 projects i created and merge them in only one
i posted a ticket about my button issue, and you helped me with it
i'm very thankful for that
i' stuck since days with the global project that I'm trying to merge i have config errors in the overlay
it's not taking in consideration all the sensors
do you have a useful link for merging 2 or more projects into one
it can help me alot
kindly reply me as fast as you can, i'm one day away from the deadline delivery
thank you in advance
I don't think I can give you any other advice from what I stated earlier:

Just do it one step at the time and rebuild the project (pristine) after every addition. If it fails, read the error log, understand the error and try to fix it.
Be aware that some Kconfigs are dependent on others. E.g. if CONFIG_OPTION_1 depends on CONFIG_OTPION_2, you need to add both.
Could you upload the error logs here?
i have plenty of errors that i' not familiar with
Knowing that i'm new for development, i'm a bit lost
i'm seeking hep from you
i will post below my overlay, Main and sample.yaml
