Enabling SPI and TWI drivers on Zephyr

Everything is fine. I was just mixing up the devicetree drivers <zephyr/drivers/i2c.h> with the direct drivers <nrfx_twim.h>. And the fact that most NCS peripheral examples are made with the direct drivers was confusing. Only the examples made for target chip (e.g. bme280 sensor) are made with the devicetree and Zephyr drivers.

Is this happening to only this project, or any other project with the overlay that you create?

Can you exit and restart the VS code and see if it configures correctly?

Once I also had a weird (but kind of same issue) that the configurations of a specific project were applied to new projects, but I got rid of that by reinstalling. That might also help.

Thanks for the example. It did not compile out of the box, because the path to the devicetree file contains folder names on your local drive. But after changing that, i did build. And I was focusing on the build lines regarding the devicetree: (I shortened the project paths for simplicity)

-- Found BOARD.dts: C:/ncs/v2.5.1/zephyr/boards/arm/nrf52840dk_nrf52840/nrf52840dk_nrf52840.dts
-- Found devicetree overlay: C:/.../hello_world_2/nrf52840dk_nrf52840.overlay
-- Found devicetree overlay: nrf52840dk_nrf52840.overlay
-- Generated zephyr.dts: C:/.../hello_world_2/build/zephyr/zephyr.dts
-- Generated devicetree_generated.h: C:/.../hello_world_2/build/zephyr/include/generated/devicetree_generated.h
-- Including generated dts.cmake file: C:/.../hello_world_2/build/zephyr/dts.cmake

And the I compared it with the build output from my project.

-- Found BOARD.dts: C:/ncs/v2.5.1/zephyr/boards/arm/nrf52dk_nrf52832/nrf52dk_nrf52832.dts
-- Generated zephyr.dts: C:/.../display-demo/build_1/zephyr/zephyr.dts
-- Generated devicetree_generated.h: C:/.../display-demo/build_1/zephyr/include/generated/devicetree_generated.h
-- Including generated dts.cmake file: C:/.../display-demo/build_1/zephyr/dts.cmake

Therefore I verified the build configuration, where devicetree overlays can be added. It was missing. I believed that I just forgot it (or did not know anything about it). I added it, and hit the "Build Configuration" Button. BUT: No change. I looked at the build configuration once again, and the reference to the devicetree overlay was empty again.

Byt why . . . ? ? ?

I am using NCS 2.6.1, and I am not getting any issue: can build and flash

Just attaching the whole project (with the build folder as well).
